1. Overview of low-density sponge catalyst SMP

1.1 Definition and Classification

The low-density sponge catalyst SMP is a porous material with a microporous structure, usually composed of a polymer matrix and evenly distributed tiny bubbles. According to its preparation method and application field, SMP can be divided into the following categories:

  • Physical foaming SMP: A microporous structure is formed in the polymer matrix through physical foaming agents (such as carbon dioxide, nitrogen, etc.).
  • Chemical foamed SMP: generates gas through chemical reactions, which expands the polymer matrix to form micropores.
  • Supercritical fluid foamed SMP: Use supercritical fluids (such as supercritical carbon dioxide) as foaming agent to prepare materials with uniform microporous structure.
1.2 Preparation process

The preparation process of SMP mainly includes the following steps:

  1. Raw material selection: Select suitable polymer matrix materials, such as polyurethane (PU), polyethylene (PE), polypropylene (PP), etc.
  2. Foaming agent addition: Select a suitable foaming agent, such as a physical foaming agent or a chemical foaming agent, according to the desired micropore structure.
  3. Foaming process: The foaming agent is decomposed or expanded in the polymer matrix by heating, pressurization, etc. to form a microporous structure.

2. Innovative application of SMP in automotive interior parts manufacturing

2.1 Reduce weight and improve fuel efficiency

Auto lightweighting is one of the important development trends of the modern automobile industry. As a low-density material, SMP can significantly reduce the weight of parts while ensuring sufficient strength. Research shows that using SMP instead of traditional high-density materials can reduce the weight of automotive interior parts by more than 30% (Wang et al., 2021). This not only helps reduce the quality of the vehicle, but also effectively improves fuel efficiency and reducesExhaust emissions.

2.2 Improve comfort and safety

SMP’s microporous structure gives it excellent sound absorption and shock absorption performance, can effectively absorb noise in the car and improve driving comfort. In addition, SMP also has good buffering performance, which can effectively absorb impact energy in case of collisions and protect passenger safety. Experimental data show that the sound absorption coefficient of SMP materials can reach more than 0.8, which is much higher than that of traditional materials (Li et al., 2020). Therefore, the application of SMP in interior parts such as car seats, door panels, ceilings, etc. can not only improve the driving experience, but also enhance the safety performance of the vehicle.

2.3 Improve thermal management and energy saving effects

SMP’s low thermal conductivity makes it an ideal thermal insulation material. In automotive interior parts, SMP can effectively prevent heat transfer, keep the interior temperature stable, and reduce the energy consumption of the air conditioning system. Research shows that the temperature fluctuations in the vehicle using SMP materials are small and the operating frequency of the air conditioning system is reduced, thus achieving energy saving effects (Chen et al., 2019). In addition, SMP also has good high temperature resistance, can maintain stable physical and chemical properties in extreme environments, and extends the service life of the interior parts.

2.4 Improve environmental performance

As environmental regulations become increasingly strict, automakers are paying more and more attention to the recyclability and environmental protection of materials. The matrix of SMP materials is usually a recyclable polymer, and the foaming agent (such as carbon dioxide) used during its preparation is itself an environmentally friendly gas. Compared with traditional organic foaming agents, the production process of SMP is more environmentally friendly and reduces environmental pollution. In addition, SMP materials can further improve their environmental performance by adding bio-based materials or degradable materials (Zhang et al., 2022).

2.5 Enhanced design flexibility

The microporous structure of SMP materials makes it have good flexibility and plasticity, and can be easily processed into various complex shapes. This provides more creative space for automotive designers, making the interior parts design more diverse and personalized. For example, SMP can be used to manufacture instrument panels, handrails and other components with complex curved surfaces, which not only meets functional needs but also enhances visual aesthetics. In addition, the surface of SMP material can be decorated by spraying, printing, etc., further enriching the appearance effect of the interior parts (Kim et al., 2021).

Innovative use of polyurethane catalyst 9727 in car seat manufacturing

2月 15th, 2025 News

Introduction

Polyurethane (PU) is a high-performance polymer material and is widely used in many fields such as automobile manufacturing, construction, and home furnishing. In car seat manufacturing, polyurethane foam is highly favored for its excellent cushioning, comfort and durability. However, the production process of polyurethane foam is complex, especially during foaming and curing, and the choice of catalyst is crucial. Although traditional polyurethane catalysts can meet basic production needs, there is still room for improvement in performance in certain special applications, such as car seat manufacturing.

In recent years, as the automotive industry’s requirements for lightweight, environmental protection and intelligence have been continuously improved, the research and development of polyurethane catalysts has also entered a new stage. As a new type of polyurethane catalyst, 9727 has gradually emerged in car seat manufacturing with its unique chemical structure and excellent catalytic properties. This article will discuss in detail the innovative use of 9727 catalyst in automobile seat manufacturing, analyze its product parameters, application scenarios, advantages and future development trends, and cite relevant domestic and foreign literature for support.

9727 Chemical structure and mechanism of catalyst

9727 Catalyst is a highly efficient polyurethane catalyst based on organometallic compounds, and its main component is Dibutyltin Dilaurate (DBTDL). DBTDL is a common organic tin catalyst with high catalytic activity and selectivity, and can promote the reaction between isocyanate and polyol at lower temperatures to form polyurethane foam. Compared with traditional amine catalysts, DBTDL can not only accelerate the reaction rate, but also effectively control the exothermic process of the reaction to avoid foam collapse or surface defects caused by overheating.

9727 Chemical structure of catalyst

The chemical structure of the 9727 catalyst is as follows:

  • Molecular formula: C30H58O4Sn
  • Molecular Weight: 610.08 g/mol
  • Appearance: Colorless to light yellow transparent liquid
  • Density: 1.02 g/cm³ (25°C)
  • Solubilization: Easy to soluble in organic solvents, slightly soluble in water

The molecular structure of DBTDL contains two long-chain fatty acid groups (lauric acid), which makes it have good compatibility and dispersion and can be evenly distributed in the polyurethane system, thus ensuring the effectiveness of the catalyst. In addition, DBTDL’s tin atoms have a strong combinationThe positioning capacity can form a stable complex with isocyanate groups, further improving the catalytic efficiency.

9727 Mechanism of action of catalyst

9727 The main function of the catalyst is to promote the formation of polyurethane foam by accelerating the reaction between isocyanate and polyol. Specifically, the tin atoms in DBTDL can coordinate with isocyanate groups (-NCO), reducing their reaction activation energy, thereby accelerating the reaction rate. At the same time, DBTDL can also regulate the exothermic process of the reaction to prevent too severe reactions from causing foam collapse or surface defects.

In addition, the 9727 catalyst also has a certain delay effect, which can inhibit the occurrence of side reactions at the beginning of the reaction and ensure the smooth progress of the main reaction. This delay effect helps improve the stability and uniformity of the foam, reduces the size difference of bubbles, and thus improves product quality.

9727 Product parameters of catalyst

To better understand the application of 9727 catalyst in car seat manufacturing, the following are its detailed product parameters:

At the same time, its good thermal stability and delay effect make it suitable for a variety of complex production processes, especially suitable for the strict requirements on foam quality and performance in car seat manufacturing.

Application of 9727 Catalyst in Car Seat Manufacturing

As an important part of the interior of the vehicle, the car seat needs not only to provide a comfortable riding experience, but also to have good safety and durability. Polyurethane foam has become one of the commonly used materials in car seat manufacturing due to its excellent cushioning properties and plasticity. However, traditional catalysts have some problems in the production process of polyurethane foam, such as unstable reaction rate, foam collapse, surface defects, etc. These problems directly affect the quality and performance of the seat.

The emergence of 9727 catalysts has brought new solutions to car seat manufacturing. The following are the specific applications and advantages of 9727 catalyst in automotive seat manufacturing:

1. Improve the uniformity and stability of foam

In car seat manufacturing, the uniformity and stability of foam are important indicators for measuring product quality. Due to the uneven reaction rate of traditional catalysts, they can easily lead to different sizes of bubbles inside the foam and even local collapse. With its efficient catalytic activity and delay effect, the 9727 catalyst can effectively control the exothermic process of the reaction and ensure that the foam maintains a stable expansion rate during the foaming process. Experimental data show that the polyurethane foam produced using 9727 catalyst has uniform bubble size and the foamThe structure is denser and the surface is smooth and defect-free.

2. Improve seat comfort and support

The comfort and support of the car seats directly affect the riding experience of the driver and passengers. The hardness and elasticity of polyurethane foam are key factors that determine seat comfort and support. The 9727 catalyst can accurately regulate the reaction ratio between isocyanate and polyol, thereby adjusting the hardness and elasticity of the foam. Studies have shown that the polyurethane foam produced using 9727 catalyst has moderate hardness and good elasticity, and can maintain good support performance after long-term use, avoiding seat deformation or collapse.

3. Improve the safety of the seat

The safety of car seats is one of the concerns manufacturers have. The durability and impact resistance of polyurethane foam are directly related to the performance of the seat in collision accidents. The 9727 catalyst can significantly improve the cross-linking density of the foam, enhance the mechanical strength and tear resistance of the foam. Experimental results show that the polyurethane foam produced using 9727 catalyst shows better compressive resistance and rebound performance when subjected to external impact, can effectively absorb impact energy and protect the safety of drivers and passengers.

4. Reduce production costs

In car seat manufacturing, production cost is an important consideration. Due to the unstable reaction rate of traditional catalysts, they often need to extend the production cycle or increase the amount of raw materials, resulting in an increase in production costs. With its efficient catalytic activity, the 9727 catalyst can complete the foam foaming and curing process in a short time, shorten the production cycle and reduce energy consumption. In addition, the amount of 9727 catalyst is relatively small, which can reduce the amount of catalyst used while ensuring product quality and further reduce production costs.

Comparison between 9727 Catalyst and other catalysts

To show the advantages of the 9727 catalyst more intuitively, we compared it with other common catalysts. The following is a comparison table of performance of several typical catalysts:

Catalytic Type Reaction rate Foam uniformity Foam Stability Cost-effective Environmental Remarks
9727 Catalyst (DBTDL) Quick Outstanding Outstanding High Better Applicable to high demanding car seat manufacturing
Amine Catalyst in General General Low Poor Response violently and easily lead to surface defects
Tin Catalyst (Other) in General General in Better The performance is relatively stable, but the reaction rate is slower
Titanate catalyst Slow General General Low Better Applicable in low temperature environments, but the reaction rate is slower

It can be seen from the table that the 9727 catalyst shows obvious advantages in terms of reaction rate, foam uniformity and stability. In particular, its efficient catalytic activity and good delay effect enable it to complete the foam foaming and curing process in a short time, while ensuring the quality and performance of the foam. In contrast, although traditional amine catalysts have low cost, they are prone to foam collapse or surface defects due to excessive reactions, which affects product quality. Although other types of tin catalysts and titanate catalysts have relatively stable performance, their reaction rates are slow and cannot meet the needs of efficient production.

9727 Catalyst Application Prospects and Challenges

As the automotive industry continues to increase its requirements for lightweight, environmental protection and intelligence, the research and development of polyurethane catalysts is also constantly improving. With its excellent catalytic performance and wide applicability, 9727 catalyst has become an indispensable key material in the manufacturing of automobile seats. However, the application of 9727 catalyst also faces some challenges, such as environmental protection, cost control and technological upgrades.

1. Environmental protection

In recent years, environmental protection regulations have become increasingly strict, especially in the automobile manufacturing industry, which have put forward higher requirements for the use of chemicals. Although the 9727 catalyst has good environmental protection properties, its main component DBTDL is still an organic tin compound, and long-term exposure may have a certain impact on human health and the environment. Therefore, one of the future research directions is how to develop more environmentally friendly alternatives, or to reduce the use of DBTDL by improving production processes and reducing its impact on the environment.

2. Cost control

Although the 9727 catalyst performs well in improving product quality and production efficiency, its high price remains an important factor restricting its widespread use. To reduce production costs, manufacturers can consider optimizing formulation design, reducing catalyst usage, or looking for more cost-effective alternatives. In addition, with the advancement of technology and the advancement of large-scale production, the cost of 9727 catalyst is expected to gradually reduce, thereby further expanding its market share.

3. Technology upgrade

With the rapid development of the automotive industry, the demand for polyurethane foam is also changing. In the future, the research and development of polyurethane catalysts will pay more attention to intelligence and multifunctionality. For example, developing polyurethane foams with self-healing functions, or improving the mechanical properties and durability of the foam by introducing nanomaterials. As one of the more advanced catalysts on the market, 9727 catalyst is expected to play a greater role in these emerging fields in the future.

Conclusion

To sum up, 9727 catalyst has been widely used in car seat manufacturing due to its efficient catalytic activity, good delay effect and excellent foam performance. Compared with traditional catalysts, the 9727 catalyst can not only improve the uniformity and stability of the foam, but also improve the comfort and safety of the seat while reducing production costs. However, the application of 9727 catalyst also faces challenges such as environmental protection, cost control and technological upgrades. In the future, with the continuous advancement of technology and changes in market demand, the 9727 catalyst is expected to play a more important role in car seat manufacturing and make greater contributions to the sustainable development of the industry.
