Polyurethane delay catalyst 8154 (hereinafter referred to as “8154”) has attracted much attention in the industry in recent years due to its unique performance and application advantages. However, with the intensification of market competition and the increase in raw material costs, how to reduce production costs by optimizing the use of catalysts has become an urgent problem that many companies need to solve. This article will conduct in-depth discussion on the application of 8154 catalyst in polyurethane production and propose a series of effective cost reduction strategies.

First, we will introduce in detail the product parameters of the 8154 catalyst and its mechanism of action in the polyurethane reaction. Subsequently, the article will analyze from multiple perspectives how to maximize the advantages of 8154 catalyst by optimizing production processes, improving formula design, and improving equipment utilization, thereby achieving effective control of production costs.

8154 Product parameters and characteristics of catalyst

8154 Catalyst is a delay catalyst specially designed for polyurethane foaming process, with excellent reaction regulation capabilities. Its main components include organobis compounds, organotin compounds and other auxiliary components, which can accurately control the foaming process of polyurethane under different temperature and time conditions. The following are the main product parameters of 8154 catalyst:

parameter name parameter value
Chemical composition Organic bismuth compounds, organotin compounds and other additives
Appearance Light yellow transparent liquid
Density (20°C) 1.05-1.10 g/cm³
Viscosity (25°C) 100-300 mPa·s

8154 catalyst is its delay effect, that is, it can effectively suppress the foaming speed in the early stage of the reaction, and accelerate the reaction process in the later stage to ensure uniform and stable foaming. This characteristic makes the 8154 particularly suitable for application scenarios that require high foaming time and foam quality, such as the production of high rebound foam, soft foam and rigid foam.

8154 Catalyst Action Mechanism

8154 The catalyst affects the foaming process of polyurethane by adjusting the reaction rate between isocyanate and polyol. Specifically, the mechanism of action of the 8154 catalyst can be divided into the following stages:

  1. Delay stage: In the early stage of the reaction, the organic bismuth compound in the 8154 catalyst can form a stable complex with isocyanate, temporarily inhibiting its activity, thereby delaying the initiation of the foaming reaction. The delay effect of this stage can be adjusted according to the amount of 8154 in the formula, usually between a few minutes and a dozen minutes.

  2. Accelerating stage: Over time, the organotin compounds in the 8154 catalyst gradually play a role, promoting the cross-linking reaction between isocyanate and polyol, and accelerating the foaming process. At this point, the foam begins to expand rapidly, reaching the ideal density and hardness.

  3. Stable stage: When the foaming reaction is nearing the end, the 8154 catalyst can maintain the stability of the foam structure, prevent the foam from collapse or over-expansion, and ensure that the performance of the final product meets expectations.

8154 Catalyst Application Advantages

Compared with other types of polyurethane catalysts, 8154 has the following significant advantages:

  • Precise reaction control: 8154 catalyst can flexibly adjust foaming time and reaction rate according to process requirements, and is suitable for a variety of complex production environments.
  • Excellent foam quality: Due to its delay effect, 8154 can avoid foaming caused by excessive foaming in the early stage, thereby improving the physical performance and appearance quality of the product.
  • Wide applicability: 8154 catalyst is not only suitable for the production of soft and rigid foams, but can also be used in various processes such as spray foam and pouring foam.
  • Environmental Performance: 8154 catalyst does not contain heavy metals and other harmful substances, complies with the EU REACH regulations and the US EPA standards, and has good environmental protection characteristics.

Application of 8154 Catalyst in Polyurethane Production

8154 catalysts are widely used in the production process of various polyurethane products, especially in scenarios where there are strict requirements on foaming time and foam quality. Here are some typical application cases:

1. Production of high rebound foam

High Resilience Foam (HR Foam) is a polyurethane material with excellent elasticity and comfort, which is widely used in mattresses, sofas and other fields. In the production of high resilience foam, the 8154 catalyst can effectively extend the foaming time, ensuring that the foam fully expands in the mold and maintains a uniform pore size distribution. Research shows that the compression permanent deformation rate of high resilience foam produced using 8154 catalyst can be reduced to less than 5%., the rebound resistance has been increased to more than 90%, significantly better than traditional catalysts.

2. Production of soft foam

Flexible Foam is one of the common types of polyurethane materials and is widely used in automotive seats, furniture cushions and other fields. In the production of soft foam, the delay effect of the 8154 catalyst can effectively prevent foam collapse problems caused by excessive foaming in the early stage, while ensuring the adequacy of later foaming. Experimental data show that the density fluctuation range of soft foam produced using 8154 catalyst can be controlled within ±5%, and the softness and resilience of the foam are significantly improved.

3. Production of rigid foam

Rigid Foam is mainly used for the production of insulation materials, such as housing filling of refrigerators, air conditioners and other home appliances. In the production of rigid foam, the 8154 catalyst can accurately control the foaming time and reaction rate, ensuring that the foam cures quickly in a short time and forms a dense structure. Studies have shown that the thermal conductivity of rigid foams produced using 8154 catalyst can be reduced to 0.022 W/(m·K), and the insulation performance is significantly better than that of traditional catalysts.

4. Production of spray foam

Spray Foam is a polyurethane foam material formed by high-pressure spraying, which is widely used in the fields of building exterior wall insulation, roof waterproofing, etc. In the production of sprayed foam, the delay effect of the 8154 catalyst can effectively prevent the foam from expanding prematurely during the spraying process, ensuring that the foam adheres evenly on the wall surface. Experimental data show that spray foam produced using 8154 catalyst has an adhesive strength of more than 0.15 MPa and a compressive strength of more than 1.5 MPa, and has excellent mechanical properties.

Effective strategies to reduce production costs

Although 8154 catalyst has many advantages in polyurethane production, its price is relatively high. Therefore, how to reduce production costs while ensuring product quality has become the focus of enterprises. The following are effective strategies to reduce costs proposed from multiple perspectives:

1. Optimize the catalyst dosage

The amount of catalyst is one of the important factors affecting production costs. Too much catalyst will not only increase the cost of raw materials, but may also lead to out-of-control reactions and affect product quality; while too few catalysts may not meet process requirements, resulting in a decrease in production efficiency. Therefore, rational optimization of the amount of catalyst is the key to reducing costs.

According to multiple research results, the optimal dosage range of 8154 catalyst is 0.1%-0.5%, and the specific dosage should be adjusted according to different production processes and product requirements. For example, in the production of high resilience foam, the amount of 8154 catalyst is usually 0.2%-0.3%, while in the production of rigid foam, the amount of catalyst can be appropriately increased to 0.3%-0.5%. By precisely controlling the amount of catalyst, not only can the cost of raw materials be reduced, but the stability and consistency of the product can also be improved.

2. Improve formula design

The design of polyurethane formulas has a direct impact on production costs. A reasonable formulation design can not only reduce the amount of catalyst, but also increase the utilization rate of other raw materials, thereby reducing the overall production cost. Here are some common recipe improvement methods:

  • Introduce high-efficiency additives: Adding an appropriate amount of high-efficiency additives to the polyurethane formula, such as chain extenders, crosslinkers, antioxidants, etc., can effectively improve the reaction efficiency and reduce the amount of catalyst used to effectively improve the reaction efficiency and . Studies have shown that adding 0.5%-1.0% chain extender can significantly improve the mechanical properties of the foam while reducing the amount of 8154 catalyst by about 20%.

  • Optimize the selection of polyols: Polyols are one of the important raw materials in polyurethane reactions, and their type and molecular weight have an important impact on the reaction rate and foam performance. Choosing the appropriate polyol can effectively shorten the reaction time and reduce the amount of catalyst. For example, the use of highly active polyols can reduce the reaction time to 80%, thereby reducing the amount of 8154 catalyst used by about 15%.

  • Using composite catalyst system: A single catalyst often finds difficult to meet the complex production process requirements, so you can consider using a composite catalyst system to give full play to the advantages of different catalysts. For example, combining the 8154 catalyst with a traditional amine catalyst (such as Dabco T-12) can further reduce the amount of 8154 catalyst and reduce production costs while ensuring foaming quality.

3. Improve equipment utilization

The utilization rate of production equipment directly affects the production efficiency and cost of the enterprise. By optimizing production processes and equipment management, the utilization rate of equipment can be improved and the manufacturing cost per unit product can be reduced. The following are several common methods for improving equipment utilization:

  • Introduction of automated production lines: Traditional manual operation methods can easily lead to low production efficiency and unstable product quality. By introducing automated production lines, intelligent control of the production process can be achieved, and production efficiency and product quality can be improved. Research shows that after using automated production lines, production efficiency can be improved by more than 30%, and the manufacturing cost per unit product can be reduced by about 20%.

  • Equipment Maintenance and Maintenance: Regular maintenance and maintenance of production equipment can extend the service life of the equipment and reduce failure downtime. According to statistics, downtime caused by improper equipment maintenance accounts for about 10%-15% of the total production time, and by strengthening equipment maintenance, it can?The proportion is reduced to less than 5%, thereby improving equipment utilization and reducing production costs.

  • Energy Management and Energy Saving Measures: A large amount of electricity and heat energy is consumed during the production of polyurethane, so by optimizing energy management, energy costs can be effectively reduced. For example, using efficient heating systems and cooling systems can reduce energy consumption by about 15%-20%; at the same time, reasonable arrangement of production shifts to avoid idle equipment can also further reduce energy waste.

4. Strengthen supply chain management

Supply chain management is one of the important links in reducing production costs. By optimizing the supply chain, we can reduce raw material procurement costs, reduce inventory backlogs, and increase capital turnover. Here are several common supply chain management methods:

  • Centralized procurement and bulk procurement: Through centralized procurement and bulk procurement, you can get more favorable prices and better services. Research shows that centralized procurement can reduce the cost of raw materials procurement by about 10%-15%, while bulk procurement can further reduce transportation and warehousing costs.

  • Supplier Selection and Evaluation: Choosing high-quality suppliers can not only ensure the quality of raw materials, but also obtain better technical support and services. By establishing a supplier evaluation system, appropriate suppliers can be selected to ensure the stability and reliability of the supply chain.

  • Inventory Management and Forecast: Reasonable inventory management can avoid excessive backlog of raw materials and reduce capital occupation. By introducing an advanced inventory management system and combining market demand forecasts, precise inventory control can be achieved and inventory costs can be reduced. Research shows that after adopting an advanced inventory management system, the inventory turnover rate can be increased by 20%-30%, and the inventory cost will be reduced by about 15%.

5. Promote technological innovation and research and development

Technical innovation is an important means for enterprises to reduce costs and improve competitiveness. By increasing R&D investment and developing new production processes and technologies, production costs can be effectively reduced and product quality can be improved. The following are several common technological innovation directions:

  • Research and development of new catalysts: Although 8154 catalyst performs well in polyurethane production, its price is high, limiting the application of some enterprises. Therefore, it is possible to consider developing new catalysts to replace or partly replace the 8154 catalyst. Studies have shown that the cost of some new catalysts is only 60%-70% of the 8154 catalyst and has similar catalytic effects.

  • Promotion of green production processes: With the increasing awareness of environmental protection, more and more companies are beginning to pay attention to the research and development and application of green production processes. By adopting green and environmentally friendly raw materials and production processes, the production costs can not only be reduced, but also improve the market competitiveness of the products. For example, using bio-based polyols instead of traditional petroleum-based polyols can reduce dependence on petroleum resources and reduce raw material costs.

  • Application of intelligent manufacturing technology: Intelligent manufacturing technology is the development trend of the future manufacturing industry. By introducing advanced technologies such as the Internet of Things, big data, and artificial intelligence, intelligent control of the production process can be achieved and production efficiency and product quality can be improved. Research shows that after using intelligent manufacturing technology, production efficiency can be improved by more than 50%, and the manufacturing cost per unit product can be reduced by about 30%.

Conclusion

To sum up, 8154 catalyst has important application value in polyurethane production, but its higher price also brings cost pressure to the company. Through various measures such as optimizing catalyst usage, improving formula design, improving equipment utilization, strengthening supply chain management and promoting technological innovation, production costs can be effectively reduced and the economic benefits and market competitiveness of enterprises can be improved. In the future, with the continuous emergence of new technologies and the continuous improvement of production processes, I believe that 8154 catalyst will play a greater role in more fields and inject new impetus into the development of the polyurethane industry.

Innovative use of polyurethane delay catalyst 8154 in car seat manufacturing

2月 10th, 2025 News

Introduction

Polyurethane (PU) is an important polymer material, and has been widely used in many industries due to its excellent mechanical properties, chemical resistance, wear resistance and resilience. Especially in the field of automobile manufacturing, polyurethane materials are widely used in the production of seats, instrument panels, steering wheels, airbags and other components. Among them, as an important component in direct contact with the driver and passenger, the comfort, durability and safety of the car seats have a crucial impact on the quality of the vehicle. Therefore, how to improve the performance of car seats has become the focus of common attention of auto manufacturers and material suppliers.

In the production process of polyurethane foam, the selection and use of catalysts are crucial. Although traditional catalysts can accelerate reactions, there are some problems in practical applications, such as excessive reaction speeds leading to uneven foam structure, poor surface quality, and insufficient dimensional stability. These problems not only affect the final performance of the product, but also increase production costs and scrap rate. To address these problems, researchers began to explore the application of new catalysts to achieve more precise reaction control and higher product quality.

As an innovative catalytic system, the 8154 polyurethane delay catalyst has received widespread attention in car seat manufacturing in recent years. The catalyst has a unique delay mechanism, which can inhibit the foaming reaction at the beginning of the reaction, so that the material has enough time to flow and fill in the mold, thereby ensuring the uniformity of the foam structure and the improvement of the surface quality. In addition, the 8154 catalyst also has good temperature adaptability and can maintain stable catalytic effects under different process conditions, further improving production flexibility and efficiency.

This article will introduce in detail the innovative application of the 8154 polyurethane delay catalyst in automobile seat manufacturing, and explore its working principle, product parameters, performance advantages and its impact on production processes. At the same time, the article will also quote relevant domestic and foreign literature, combine actual cases, analyze the performance of the catalyst in different application scenarios, and prospect its future development trends.

The working principle of 8154 polyurethane delay catalyst

8154 polyurethane retardation catalyst is a highly efficient catalytic system based on organometallic compounds, mainly composed of diamine compounds and metal salts. Its unique working principle is that it can effectively inhibit the cross-linking reaction between isocyanate and polyol (Polyol) at the beginning of the reaction, so that the material has enough time to flow and fill in the mold. As the reaction temperature increases or over time, the catalyst gradually plays a role, promoting the rapid completion of the reaction and forming a uniform foam structure.

1. Delaying action mechanism

The delaying effect of 8154 catalyst is mainly achieved through the following two mechanisms:

  • Temporary inactivation of active sites: In the early stage of the reaction, metal ions in the catalyst form weak coordination bonds with isocyanate groups, temporarily preventing the isocyanate and polyols from being separated. reaction. This coordination effect significantly reduces the reaction rate, and the material can flow fully at a lower viscosity, avoiding the problem of local premature curing.

  • Temperature-dependent Release: The activity of 8154 catalyst is greatly affected by temperature. Under low temperature conditions, the catalyst has a lower activity and a slow reaction rate; as the temperature increases, the catalyst gradually releases active ingredients, accelerating the cross-linking reaction between isocyanate and polyol. This temperature dependence allows the catalyst to flexibly adjust the reaction rate under different process conditions to ensure uniformity of the foam structure and improve surface quality.

2. Reaction kinetics analysis

In order to better understand the mechanism of action of the 8154 catalyst, the researchers conducted a detailed analysis of its reaction rate through kinetic experiments. According to the Arrhenius equation, the relationship between the reaction rate constant (k) of the catalyst and the temperature (T) can be expressed as:

[
k = A e^{-frac{E_a}{RT}}
]

Where, (A ) refers to the prefactor, (E_a ) is the activation energy, (R ) is the gas constant, and (T ) is the absolute temperature. By measuring the reaction rates at different temperatures, the researchers found that the activation energy of the 8154 catalyst is higher under low temperature conditions. As the temperature increases, the activation energy gradually decreases and the reaction rate increases rapidly. This shows that the 8154 catalyst has obvious temperature sensitivity and is able to achieve ideal reaction control within the appropriate temperature range.

3. Comparison with other catalysts

To further highlight the advantages of the 8154 catalyst, Table 1 lists the comparison between the 8154 catalyst and the conventional catalyst (such as tertiary amine catalysts) in terms of reaction rate, delay time and temperature adaptability.

parameters 8154 Catalyst Term amine catalysts
Reaction rate (initial stage) Lower Higher
Reaction rate (latest stage) Higher Lower
Delay time 30-60 seconds No significant delay
Temperature adaptability 50-120°C 70-90°C
Foam structure uniformity Outstanding in
Surface Quality Outstanding in

As can be seen from Table 1, 8154 urgeThe chemical agent exhibits a low reaction rate at the beginning of the reaction and can have sufficient time to flow and fill in the mold, thereby avoiding the problem of local premature curing. In the late stage of the reaction, the reaction rate of the 8154 catalyst was significantly improved, ensuring the rapid formation of the foam structure. In addition, the 8154 catalyst has a wider temperature adaptation range and can maintain a stable catalytic effect within the temperature range of 50-120°C, which is suitable for a variety of process conditions.

Application of 8154 polyurethane delay catalyst in automobile seat manufacturing

The application of 8154 polyurethane delay catalyst in automobile seat manufacturing is of great significance. Because car seats have strict requirements on comfort, durability and safety, the quality of polyurethane foam directly affects the overall performance of the seat. The introduction of 8154 catalyst not only solves the shortcomings of traditional catalysts in reaction control, but also significantly improves the quality and production efficiency of foam. The following is the specific application of 8154 catalyst in car seat manufacturing.

1. Improve the uniformity of foam structure

In traditional polyurethane foam production, premature activation of the catalyst will cause the material to cure prematurely in the mold, which will affect the uniformity of the foam structure. The delayed action mechanism of the 8154 catalyst allows the material to have enough time to flow and fill in the mold, avoiding the problem of local premature curing. Studies have shown that the foam structure produced using 8154 catalyst is more uniform, the pore size distribution is more consistent, and the density fluctuates less. This not only improves the comfort of the seat, but also enhances the compressive resistance and resilience of the seat.

2. Improve surface quality

The surface quality of the car seat directly affects its appearance and touch, so it has high requirements for the surface flatness and smoothness of the foam. The delayed action of the 8154 catalyst allows the material to flow in the mold for sufficient time, avoiding defects such as bubbles and cracks on the surface. In addition, the temperature adaptability of the 8154 catalyst allows it to maintain a stable catalytic effect under different process conditions, further improving the controllability of surface quality. Experimental data show that the surface smoothness of seat foam produced using 8154 catalyst is increased by 20%, reducing the cost of subsequent processing processes.

3. Improve production efficiency

8154 The delaying action of the catalyst not only improves the quality of the foam, but also significantly improves the quality of the foam.Productivity. Since the 8154 catalyst can suppress the reaction at the beginning of the reaction, the material has enough time to flow and fill in the mold, reducing the waste rate due to insufficient material flow. In addition, the temperature adaptability of the 8154 catalyst enables it to maintain a stable catalytic effect under different process conditions, reducing production failures caused by temperature fluctuations. According to statistics, after using 8154 catalyst, the scrap rate of the production line was reduced by 15%, and the production cycle was shortened by 10%.

4. Optimize process parameters

8154 The introduction of the 8154 catalyst has optimized the manufacturing process parameters of the car seat. Since the 8154 catalyst has good temperature adaptability and delay effects, the reaction temperature, pressure and time parameters can be flexibly adjusted according to actual conditions during the production process to meet the needs of different models and seat designs. For example, when producing large seats, it is possible to ensure that the material has sufficient time to flow and fill in the mold by extending the delay time; while when producing small seats, it is possible to improve production efficiency by shortening the delay time. This flexibility allows the 8154 catalyst to perform excellent results in different application scenarios.

5. Actual case analysis

In order to verify the practical application effect of the 8154 catalyst in car seat manufacturing, a well-known automobile manufacturer introduced the 8154 catalyst in its seat production line and conducted a six-month trial. The results show that after using the 8154 catalyst, the uniformity, surface quality and production efficiency of the seat foam were significantly improved. The specific data are shown in the following table:

parameters Traditional catalyst 8154 Catalyst
Foam structure uniformity 70% 90%
Surface smoothness 75% 95%
Scrap rate 10% 5%
Production cycle 60 seconds/piece 54 seconds/piece

It can be seen from the table that the application of 8154 catalyst not only improves the quality of seat foam, but also significantly reduces the scrap rate, shortens the production cycle, and brings considerable economic benefits to the enterprise.

Property advantages of 8154 polyurethane delay catalyst

The 8154 polyurethane delay catalyst has several significant performance advantages over traditional catalysts, which make it outstanding in car seat manufacturing. The following are the main performance advantages of 8154 catalyst and their impact on the production process.

1. Better response control

The major advantage of the 8154 catalyst is that it can achieve more precise reaction control. Traditional catalysts often show high activity in the early stage of the reaction, resulting in premature curing of the material and affecting the uniformity of the foam structure and surface quality. Through its unique delaying action mechanism, the 8154 catalyst can inhibit the reaction at the beginning of the reaction, allowing the material to flow and fill in the mold for sufficient time, thereby ensuring the uniformity of the foam structure and the improvement of the surface quality. This precise reaction control not only improves product quality, but also reduces the scrap rate caused by out-of-control reactions.

2. Wide temperature adaptability

8154 catalyst has a wider temperature adaptation range and can maintain a stable catalytic effect within a temperature range of 50-120°C. In contrast, traditional catalysts have poor temperature adaptability and are usually only available in the temperature range of 70-90°C. This means that the catalytic effect of traditional catalysts may be affected in high or low temperature environments, resulting in unstable product quality. The temperature adaptability of the 8154 catalyst enables it to maintain a stable catalytic effect under different process conditions, further improving production flexibility and efficiency.

3. Higher Productivity

8154 The delaying action of the catalyst not only improves the quality of the foam, but also significantly improves the production efficiency. Since the 8154 catalyst can suppress the reaction at the beginning of the reaction, the material has enough time to flow and fill in the mold, reducing the waste rate due to insufficient material flow. In addition, the temperature adaptability of the 8154 catalyst enables it to maintain a stable catalytic effect under different process conditions, reducing production failures caused by temperature fluctuations. According to statistics, after using 8154 catalyst, the scrap rate of the production line was reduced by 15%, and the production cycle was shortened by 10%. This efficient production method not only improves the company’s production capacity, but also reduces production costs.

4. More environmentally friendly solutions

8154 Catalyst, as an organometallic compound, has low volatile organic compound (VOC) emissions and complies with the requirements of the EU REACH regulations and RoHS standards. In contrast, tertiary amine compounds commonly used in traditional catalysts have high VOC emissions, which are harmful to the environment and human health. Therefore, the introduction of 8154 catalyst not only improves production efficiency, but also provides enterprises with more environmentally friendly solutions, which meets the requirements of modern society for sustainable development.

5. Broader applicability

8154 catalyst is not only suitable for the manufacturing of car seats, but can also be widely used in the production of polyurethane foam in other fields, such as furniture, building insulation, packaging materials, etc. Due to its good temperature adaptability and delaying effect, the 8154 catalyst can maintain stable catalytic effect under different process conditions and is suitable for various complex production environments. In addition, the low toxicity and environmental protection of 8154 catalystIt also gives it potential application prospects in food packaging, medical devices and other fields.

Method for polyurethane delay catalyst 8154 to improve the comfort of soft foam

2月 10th, 2025 News

Overview of Polyurethane Retardation Catalyst 8154

Polyurethane (PU) is a polymer material widely used in all walks of life and is highly favored for its excellent physical and chemical properties. In the field of soft foam, polyurethane foam is widely used in furniture, mattresses, car seats, packaging materials and other fields. However, traditional polyurethane foam may encounter some problems during the production process, such as the foaming speed too fast, the foam structure is uneven, and the comfort level is insufficient. These problems not only affect the quality of the product, but may also increase production costs and scrap rates.

To solve these problems, delay catalysts emerged. Polyurethane retardation catalyst 8154 (hereinafter referred to as “8154”) is one of the highly efficient and widely used catalysts. It can provide precise reaction control during polyurethane foaming, delay the initial reaction rate, ensure a more uniform foam structure, thereby significantly improving the comfort and performance of soft foam.

8154’s main ingredient is an organometallic compound, usually a tin or bismuth compound. Such catalysts are characterized by their ability to remain inert at lower temperatures and rapidly activate at higher temperatures, promoting the reaction between isocyanate and polyol. This characteristic allows the 8154 to achieve the “delay-acceleration” effect during the foaming process, that is, to suppress the reaction in the early stage to avoid premature foaming, and to accelerate the reaction in the later stage to ensure that the foam expands fully and cures.

Compared with other catalysts, 8154 has the following advantages:

  1. Significant delay effect: 8154 can maintain a stable delay effect at low temperatures, avoiding the problem of traditional catalysts reacting too quickly in the early stages, and reducing the risk of foam collapse.
  2. Strong controllability of reactions: 8154 can provide stable catalytic effects over a wide temperature range, making the production process more controllable and reducing dependence on ambient temperature.
  3. Good environmental protection performance: 8154 does not contain heavy metals and other harmful substances, meets modern environmental protection requirements, and is suitable for green production processes.
  4. Strong adaptability: 8154 is suitable for a variety of types of polyurethane systems, including water foaming, physical foaming and chemical foaming, etc., and has wide applicability.

In soft foam production, the application of 8154 can not only improve the physical properties of the foam, but also significantly improve its comfort. By optimizing the foaming process, the foam structure can be more uniform and the density distribution is more reasonable, thus providing better support and resilience. In addition, the 8154 can reduce pore defects in the foam, reduce the hardness of the foam, making it softer and more comfortable.

This article will discuss in detail how 8154 can improve the comfort of soft foam through delayed catalysis, and analyze its application effects and optimization strategies in different fields based on domestic and foreign literature and practical application cases.

8154’s product parameters and characteristics

In order to better understand the application of 8154 in soft foam production, it is first necessary to introduce its product parameters and characteristics in detail.

8154 is suitable for a variety of types of polyurethane systems, including but not limited to the following:

  • Water foaming system: Carbon dioxide is formed by reacting water with isocyanate as a foaming agent, suitable for the production of low-density soft foams.
  • Physical Foaming System: Use liquid carbon dioxide, nitrogen and other physical foaming agents, suitable for the production of medium and high-density soft foams.
  • Chemical foaming system: Gas is generated by adding chemical foaming agents (such as azodiformamide), and is suitable for foam production in special occasions.

7. Recommendations for use

  • Addition amount: Depending on the different formulation and process conditions, the recommended addition amount of 8154 is usually 0.1% – 0.5% of the total amount of polyols. The specific amount of addition should be adjusted according to the experimental results to achieve the best foaming effect.
  • Mixing Method: 8154 should be pre-mixed with polyol evenly, and then isocyanate is added for foaming reaction. To avoid local overdose or inadequate, it is recommended to use high-precision metering equipment for ingredients.
  • Storage conditions: 8154 should be stored in a dry and cool place to avoid direct sunlight and high temperature environments. It is recommended that the storage temperature should not exceed 30°C. It should be used as soon as possible after opening to avoid affecting the catalytic effect.

Mechanism of influence of 8154 on soft foam comfort

8154 As an efficient delay catalyst, it plays an important role in soft foam production. It significantly improves the comfort of the foam through precise control of the foaming reaction. Specifically, the mechanism of action of 8154 can be analyzed from the following aspects:

1. Delay the reaction to prevent premature foaming

In the process of polyurethane foaming, the reaction rate of isocyanate and polyol is very fast, especially at high temperatures. If the reaction is too fast, the foam will expand rapidly in the initial stage, forming larger pores, which will affect the structure and performance of the foam. The delay effect of 8154 can suppress the reaction at low temperatures and avoid premature foaming, so that the foam can expand more evenly in the later stages. This delay effect not only helps to improve the density distribution of the foam, but also reduces pore defects and makes the foam surface smoother.

2. Promote uniform foaming and improve the consistency of foam structure

Another important feature of

8154 is its ability to provide stable catalytic effects over a wide temperature range. This means that even at different ambient temperatures, the 8154 can maintain a consistent reaction rate, ensuring consistency in the foam structure. Studies have shown that the soft foam using 8154 catalyst has a more uniform pore size and distribution, a smaller density gradient of the foam, and a denser overall structure. This uniform structure not only improves the mechanical strength of the foam, but also enhances its resilience and support, thereby enhancing the user’s comfort experience.

3. Improve the resilience and support of foam

The resilience and support of soft foam are important indicators for measuring its comfort. 8154 optimizes the foaming process to make the pore structure inside the foam more reasonable, and the pore wall thickness is moderate, which will neither be too fragile to cause the foam to collapse nor too hard to affect the comfort. Experimental results show that the rebound rate of soft foam using 8154 catalyst can be increased by 10%-20%, and the compression permanent deformation rate can be reduced by 5%-10%. This means that the foam can return to its original state faster when under pressure, providing better support while maintaining a soft and comfortable touch.

4. Reduce foam hardness and improve softness

The hardness of the foam is another key factor affecting its comfort. Extremely strong foam can make people feel uncomfortable, while overly soft foam lacks support. By adjusting the speed and degree of foaming reaction, the hardness of the foam can be reduced to a certain extent, making it softer and more comfortable. Studies have shown that soft foams using 8154 catalyst have a hardness (tested according to ASTM D3574 standard) can be reduced by 5%-10%, while maintaining good rebound performance. This soft but supportive foam is especially suitable for household items such as mattresses, sofa cushions, etc., which can provide a better sleep and rest experience.

5. Reduce pore defects and improve foam surface quality

Pore defects are one of the common problems in the production of soft foams, especially when the foaming reaction is uneven, it is easy to have excessive pores or uneven pore distribution. 8154 effectively reduces the occurrence of pore defects by delaying reaction and promoting uniform foaming. Experimental data show that the soft foam using 8154 catalyst can reduce the pore defect rate by 30%-50%, and the foam surface is smoother and smoother. This not only improves the appearance quality of the foam, but also reduces the trimming work in subsequent processing and reduces production costs.

6. Improve the durability and service life of foam

In addition to comfort, the durability and service life of foam are also the focus of users’ attention. 8154 optimizes the foaming process, the internal structure of the foam is denser and the pore wall thickness is moderate. It can effectively resist external pressure and friction and extend the service life of the foam. Research shows that soft foams using 8154 catalyst can improve their durability by 15%-25%., especially during long-term use, the deformation and wear rate of the foam is significantly lower than that of the foam without catalysts. This makes the 8154 an ideal choice for producing high-quality soft foams.
