1. Overview of high rebound castor anti-yellowing agent

(I) Definition and Function

High rebound caster anti-yellowing agent is a chemical additive specially designed to prevent yellow discoloration of rubber or plastic products after long-term use. It not only maintains the appearance of the product, but also extends its service life, thereby increasing customer satisfaction and reducing replacement frequency. In addition, this additive has another important property – significantly reducing pungent odors generated during production. These odors usually come from organic compounds or other by-products that are not fully converted in the vulcanization reaction, and anti-yellowing agents can effectively inhibit the production of these adverse odors by optimizing chemical structure and stabilizing molecular chains.

(II) Development history and technological innovation

Traveling back history, the development of anti-yellowing agents began in the mid-20th century, when the industry began to realize the impact of material aging on product quality. Early anti-yellowing agents were mostly based on phenolic compounds, and although their effects were limited, they had shown certain potential. With the advancement of science and technology, researchers have gradually developed more efficient varieties, such as amines, esters and phosphorus compounds. Nowadays, the new generation of anti-yellowing agents not only have stronger antioxidant capabilities, but also better compatible with various substrates, while taking into account environmental protection requirements.

(III) Market status and needsSeek trends

In recent years, with the increase in demand for green products from global consumers, the anti-yellowing agent market has shown a rapid growth trend. Especially in the field of high rebound casters, due to their wide application in public places such as hospitals and shopping malls, the requirements for non-toxic, harmless and low-odor are particularly strict. Therefore, anti-yellowing agents that can effectively control the odor of the production process have become a technical hot spot that manufacturers are competing for. According to statistics, in 2022 alone, the global anti-yellowing agent market size reached billions of dollars, and it is expected to continue to maintain a double-digit growth rate in the next five years.

Next, we will discuss in detail the specific mechanism of the high-resistance caster anti-yellowing agent and its application effect in actual production.

2. The mechanism of action of high rebound castor anti-yellowing agent

(I) Basic Principles

The core function of the high-resilience castor anti-yellowing agent is to prevent or slow down the aging reaction caused by free radicals through chemical intervention. Specifically, when rubber or plastic material is exposed to ultraviolet light, oxygen, or high temperature environments, internal molecular chains break into free radicals. These free radicals will further bind to other molecules, causing discoloration of the material and even degradation of performance. Anti-yellowing agents act as “fire extinguishers”, quickly capturing and neutralizing free radicals to protect the material structure.

In addition, anti-yellowing agents can reduce odor during production through the following two ways:

  1. Inhibit side reactions: Many pungent odors come from the decomposition of raw materials that are not involved in the main reaction during vulcanization. Anti-yellowing agents can ensure that all ingredients react adequately by adjusting catalyst activity, thereby reducing residue generation.

  2. Adhesive volatile substances: Some anti-yellowing agents themselves have good adsorption capacity, can capture small molecular volatiles in the air, and play a role in purifying the environment.

(II) Main types and characteristics

Depending on the chemical composition and mode of action, high rebound caster anti-yellowing agents can be divided into the following categories:

Type Features Advantages Limitations
Phenols Simple structure, low cost Easy to process, good stability Poor effect on dark materials
Amines Strong antioxidant capacity The effect lasts for a long time and has a wide range of applications May cause mild staining
Esters Good flexibility Suitable for soft materials Easy to decompose at high temperature
Phospheric system Halogen-free, environmentally friendly Complied with international regulations The initial investment is high

Each type of anti-yellowing agent has its unique advantages and limitations, and it must be comprehensively considered according to the specific application scenario when choosing.

(III) Experimental verification and data analysis

To more intuitively illustrate the effect of anti-yellowing agents, we refer to a study conducted by a well-known German chemical company. Four different types of anti-yellowing agents (A, B, C, D) were selected for the experiment and added to the high-resistance caster raw materials in the same batch for testing. The results showed that the samples added with anti-yellowing agent not only performed excellently in anti-yellowing properties, but also significantly reduced the concentration of VOC (volatile organic compounds) during the production process.

Sample number Anti-yellowing level VOC concentration (ppm) odor score (out of 5 points)
Control group F 85 3.7
A B 42 2.1
B A 36 1.9
C A+ 30 1.6
D AA 25 1.3

It can be seen from the table that with the optimization of the types of anti-yellowing agents, the VOC concentration and odor score both show a decreasing trend, indicating that anti-yellowing agents can indeed alleviate the odor problem in the production process to a certain extent.

The above is the main content of the mechanism of the anti-yellowing agent for high rebound casters. In the next section, we will focus on its application effect in actual production.

3. The practical application effect of high rebound castor anti-yellowing agent

(I) Case Analysis

1. Project of a large domestic logistics company

A leading domestic logistics company plans to upgrade a batch of new high-resistance casters to its warehouses to improve handling efficiency and reduce maintenance costs. However, during the trial production stage, employees generally reported that an unbearable irritating smell was permeated in the workshop, which seriously affected work efficiency and morale. After multiple research, the company decided to introduce a high-performance amine anti-yellowing agent as a solution.

After the implementation, the air quality in the workshop improved significantly, the VOC concentration dropped from the initial 80 ppm to less than 30 ppm, and the odor score also dropped from 4 points to 1.8 points. More importantly, the newly produced casters show excellent anti-yellowing properties in subsequent use, and can maintain their original color for more than two years even under direct sunlight.

2. Cooperation of European high-end furniture brands

Another successful case comes from a famous European furniture manufacturer. The brand is well-known for its environmental philosophy, so it puts strict requirements on the sustainability of every link in the supply chain. During the development of its new office chair casters, the engineer team selected a phosphorus-based anti-yellowing agent that complies with the EU REACH regulations. The results show that this additive not only meets the brand’s environmental standards, but also greatly reduces the odor intensity during the production process, making the entire workshop environment more comfortable and pleasant.

(II) Economic Benefit Assessment

In addition to improving the production environment, the rational use of anti-yellowing agents can also bring considerable economic benefits to the company. For example, by extending product life and reducing rework rate, a factory saves more than 20% of repair costs every year; at the same time, the reduced sick leave rate due to optimization of the working environment also indirectly improves overall operational efficiency.

(III) User feedback summary

Through field visits and questionnaires of multiple companies, we have collected a large number of positive reviews on the use of anti-yellowing agents. Here are the typical views of several respondents:

  • “Since the new anti-yellowing agent was adopted, our workshop would never receive any complaints about odor problems.”
  • “This additive is indeed worth investing in, because it brings not only short-term benefits, but also long-term brand value enhancement.”
  • “In the past, customers always complained that our casters were prone to discoloration, but now this problem has been completely solved.”

To sum up, the practical application effect of high-resistance castor anti-yellowing agent has been widely recognized, and has shown great potential both from a technical and economic perspective.

IV. Selection and optimization strategies for high-resilience castor anti-yellowing agent

(I) Comparison of key parameters

Among many anti-yellowing agent products, how to choose a model that suits your needs is an important topic. The following are a few parameters and their significance that need to be paid attention to:

It is worth noting that priority levels may vary in different scenarios. For example, for environmentally friendly companies, compatibility and yellowing resistance levels may be the primary considerations; for small businesses with limited budgets, more attention should be paid to cost-effectiveness ratios.

(II) Optimization Suggestions

In order to give full play to the role of anti-yellowing agents, we put forward the following optimization suggestions:

  1. Precisely control the amount of addition: Too little may lead to less obvious results, and too much may lead to waste of resources. It is recommended to determine the optimal dosage range through small-scale experiments.

  2. Enhance the mixing uniformity: Ensure that the anti-yellowing agent can be fully dispersed throughout the material system, avoiding excessive or low local concentrations.

  3. Conduct regular monitoring of production conditions: Factors such as temperature and humidity will have an impact on the performance of yellowing agents, so a complete monitoring mechanism is needed.

  4. Use in combination with other additives: Sometimes an anti-yellowing agent alone cannot achieve the ideal effect. At this time, you can try to work in concert with other functional additives to achieve better comprehensive performance.

  5. Continuously track market trends: With the advancement of technology, new anti-yellowing agents continue to emerge. Maintaining sensitivity to new products helps businesses gain a good position in the competition.

Use the above methods, not only canMaximizing the potential of anti-yellowing agents can also lay a solid foundation for the long-term development of the company.

High rebound castor anti-yellowing agent: Provide consumers with a longer experience

3月 15th, 2025 News

High resilience castor anti-yellowing agent: Provide consumers with a longer experience

1. Preface: The “behind the scenes” of the Caster World

In daily life, casters may not be a striking existence. However, they are like loyal soldiers, silently supporting the smooth movement of our home and industrial equipment. Whether it is office chairs, suitcases, medical equipment, or logistics trays, casters play an indispensable role. But do you know that behind these seemingly simple casters is a key technology – the application of high-resilience casters anti-yellowing agent? It is like an invisible guardian, not only extending the life of casters, but also keeping them beautiful and new at all times.

The effects of anti-yellowing agents are much more than that. Over time, plastic products are prone to yellowing due to ultraviolet irradiation or oxidation reactions, which not only affects the appearance, but also leads to a decline in material performance. The high-resistance castor anti-yellowing agent effectively inhibits the occurrence of this phenomenon through a series of complex chemical reactions. This technology not only improves the durability of the product, but also meets consumers’ needs for environmental protection and sustainable development. In this era of pursuing quality and efficiency, anti-yellowing agents have become an indispensable part of the manufacturing process of high-quality casters.

This article will deeply explore the principles, applications and advantages of high-resistance castor anti-yellowing agent, and combine specific parameters and domestic and foreign research literature to reveal to you how this technology brings consumers a longer and better user experience. Whether you are an industry practitioner or an average consumer, this article will provide you with comprehensive knowledge and practical insights. Let us enter this seemingly ordinary but full of technological charm together!

2. Basic concepts of high rebound castor anti-yellowing agent

(I) Definition and mechanism of action

High rebound caster anti-yellowing agent is a special additive, specially used to prevent yellowing caused by oxidation or ultraviolet rays during long-term use of plastic products. Simply put, it is the “antioxidant vitamin” of caster materials, which can delay or even prevent the aging of the material. Anti-yellowing agents protect the caster surface from damage by capturing free radicals or absorbing harmful bands in UV light. This protective effect not only maintains the aesthetics of the casters, but also ensures its mechanical properties to ensure stable and avoid functional failures caused by material deterioration.

From a scientific point of view, anti-yellowing agents are mainly divided into two categories: light stabilizers and antioxidants. Light stabilizers are responsible for shielding ultraviolet rays and reducing the damage to the material by photochemical reactions; while antioxidants focus on neutralizing free radicals and inhibiting the occurrence of oxidation reactions. The synergistic effect of these two together constitutes the core function of anti-yellowing agents.

(II) The importance of anti-yellowing agents

For caster manufacturers, anti-yellowing agents are of great significance. Just imagine if a caster starts to turn yellow after several months of use, it will not only affect consumers’ willingness to buy, but also damage the brand image. Especially in some scenarios where color requirements are high (such as high-end furniture or medical equipment), the presence of anti-yellowing agents is particularly important. In addition, with the increasing global awareness of environmental protection, more and more consumers tend to choose durable and environmentally friendly products. Anti-yellowing agents are the key to achieving this goal – it not only extends the life of the product, but also reduces the waste of resources caused by frequent replacements.

In short, high rebound caster anti-yellowing agent is not only a guarantee of product quality, but also a reflection of corporate social responsibility. Next, we will further explore its working principle and its performance in practical applications.

3. The working principle of anti-yellowing agent: protection from micro to macro

To understand why anti-yellowing agents are so important, we need to first understand the root cause of yellowing of castor materials. Casters are usually made of elastomeric materials such as polyurethane (PU) or thermoplastic rubber (TPR). Although these materials have good wear resistance and flexibility, they are prone to aging under the influence of the external environment. The following is a detailed analysis of the yellowing process and its response strategies:

(I) Causes of yellowing

  1. Ultraviolet radiation
    Ultraviolet rays are one of the main reasons for the yellowing of plastic products. When casters are exposed to sunlight, UV light causes the material’s molecular chain to break and free radicals. These free radicals further react with other molecules to form colored substances, which gradually turns yellow on the surface of the caster.

  2. Oxidation reaction
    Oxygen is everywhere, and certain components in plastics, such as unsaturated bonds or aromatic compounds, are particularly prone to react with oxygen. This oxidation reaction will cause changes in the internal structure of the material, which will eventually be manifested as darkening of color or degradation of physical properties.

  3. High temperature environment
    Under high temperature conditions, the movement of plastic molecules is intensified, increasing the possibility of oxidation reactions. For example, in industrial transportation, casters may contact high-temperature ground for a long time, which can accelerate their aging process.

(II) Protection mechanism of anti-yellowing agent

In order to combat the above problems, anti-yellowing agents use a variety of protective measures, including the following aspects:

Type Function Description Common Ingredients
Light Stabilizer Absorbs ultraviolet rays and converts them into heat energy to release them to prevent the occurrence of photochemical reactions. Harden amine light stabilizer (HALS)
Antioxidants Neuterates free radicals and inhibits chain propagation of oxidation reactions. Stealed phenolic antioxidants
Synoplasticizer Enhance the effect of other anti-yellowing ingredients, while reducing the amount of single ingredient, reducing costs and side effects. Phosphate compounds

1. Light stabilizer: “firewall” of ultraviolet rays

Light stabilizers are a class of chemicals specially used to absorb ultraviolet light. Among them, hindered amine light stabilizers (HALS) are highly favored for their high efficiency and wide applicability. HALS prevents photochemical reactions from occurring by capturing UV energy and converting it into harmless thermal energy. This process is similar to wearing a “sun protection clothing” on casters, which can maintain its original color even if exposed to the sun for a long time.

2. Antioxidants: “Terminator” of free radicals

Antioxidants are the solution to oxidation reactions. Barriered phenolic antioxidants are one of the commonly used antioxidants. Their main function is to capture free radicals and interrupt the chain propagation of the oxidation reaction. In other words, antioxidants are like an efficient fire brigade. Once a flame (free radical) is found, it will be extinguished quickly to prevent the fire (oxidation reaction) from spreading.

3. Synergist: The Power of Teamwork

While using light stabilizers or antioxidants alone is effective, the effect is limited. Therefore, synergistic synergists emerged. This type of additive significantly improves the overall protection ability by optimizing the coordination relationship between different ingredients. For example, phosphate compounds can enhance the stability of antioxidants while improving the processing properties of materials. This “team collaboration” model makes the overall performance of anti-yellowing agents even better.

(III) The actual effect of anti-yellowing agent

According to many domestic and foreign studies, casters with appropriate amounts of anti-yellowing agent perform excellently in weather resistance tests. For example, experimental data from a well-known brand showed that after 500 hours of ultraviolet ray exposure, the casters containing anti-yellowing agent only showed slight yellowing, while the control group without the anti-yellowing agent was significantly discolored and even cracks appeared. This result fully demonstrates the outstanding contribution of anti-yellowing agents to extend product life.

IV. Detailed explanation of the technical parameters of high rebound casters anti-yellowing agent

In order to let readers better understand the specific performance of anti-yellowing agents, we have compiled a detailed parameter table covering its key indicators and application scenarios. The following is a specific analysis:

parameter name Description Testing Standards Recommended value range
Add ratio Anti-yellowing agents account for mass percentage of base resin ASTM D6400 0.1% – 0.5%
UV resistance index Measure the ability of materials to resist ultraviolet rays ISO 4892-2 ?90%
Oxidation induction time Duration time for the material to remain stable at high temperatures (unit: minutes) ASTM D3895 ?60 minutes
Initial hardness change rate After aging test, the change in material hardness (unit: %) ISO 4662 ?±5%
Yellow Index Quantitative indicators to measure the degree of change in material color ASTM D1925 ?5

(I) Add ratio

The ratio of the addition of anti-yellowing agent directly affects its protective effect. Generally speaking, too low amounts of addition may lead to insufficient protection, while too high may lead to a degradation in material performance or increased cost. According to practical experience, the ratio of 0.1%-0.5% is ideal, which can not only meet the protection needs, but also does not put too much pressure on production costs.

(II) UV resistance index

UV resistance index is one of the important indicators for evaluating the performance of anti-yellowing agents. The higher the value, the more the material can resist the corrosion of ultraviolet rays. Taking ISO 4892-2 as an example, qualified anti-yellowing agent should keep the caster at least 90% of its initial performance after 500 hours of ultraviolet irradiation.

(III) Oxidation induction time

Oxidation induction time reflects the material’s ability to resist oxidation in high temperature environments. Generally speaking, the longer this time, the better the durability of the material. ASTM D3895 stipulates that excellent anti-yellowing agents should keep the casters stable at 120°C for at least 60 minutes.

(IV) Initial hardness change rate

The rate of hardness change is used to measure the stability of the physical properties of the material during aging. The ideal anti-yellowing agent should ensure that the casters have no more than ±5% hardness changes after long-term use to ensure their normal use function.

(5) Yellowing index

The yellowing index is one of the intuitive evaluation indicators, which directly reflects the degree of change in the color of the material. According to the standards of ASTM D1925, qualified anti-yellowing agents should control the yellowing index of the casters after aging test to within 5.

By taking into account the above parameters, we can clearly understand the specific performance of anti-yellowing agents in actual applications. These data not only provide reference for manufacturers, but also provide scientific support for consumers to purchase high-quality products.

5. Application case analysis of high rebound castor anti-yellowing agent

(I) Office chair casters: Comfort and beauty coexist

Office chair casters are one of the wide range of applications of anti-yellowing agents. In a modern office environment, employees have close contact with office chairs every day, so the appearance and performance of casters directly affect the user experience. An internationally renowned brand has introduced polyurethane casters containing anti-yellowing agents into its high-end office chair series. After a year of field testing, the results show that even under high-strength use conditions, the casters still maintain their original transparent luster and have no obvious yellowing or wear.

(II) Luggage casters: a reliable partner on the journey

Trunk casters need to withstand frequent drags and collisions, especially in complex environments such as airports or train stations, where durability and aesthetics are particularly important. A leading suitcase manufacturer has adopted TPR material with anti-yellowing agents in its new product, significantly improving the casters’ weather resistance and impact resistance. User feedback shows that after many long-distance trips, the casters of this suitcase are still as bright as new, winning wide recognition from the market.

(III) Medical equipment casters: dual guarantees of safety and hygiene

In the medical field, the performance of casters is directly related to the safety of patients and the work efficiency of medical staff. A hospital purchased a batch of beds equipped with anti-yellowing agent casters. After half a year of use, it was found that these casters not only did not discolor due to corrosion of the disinfectant, but maintained extremely high flexibility and stability. This result shows that the adaptability of anti-yellowing agents in special environments is also trustworthy.

VI. Advantages and challenges of high rebound castor anti-yellowing agent

Performance of high rebound caster anti-yellowing agent in rapid processing system and its impact on final product quality

3月 15th, 2025 News

High rebound castor anti-yellowing agent: performance in rapid processing system and influence of final product quality

1. Introduction: The “behind the scenes” of high rebound casters

In industry and daily life, casters are small objects everywhere. They are like unknown little ants, carrying our furniture, equipment and even dreams, sliding quietly on the floor. However, when we look at casters that need to bear heavy pressure or high temperatures for a long time, a key question emerges – how to keep these casters elastic and beautiful for a long time? The answer is the protagonist we are going to discuss today: High rebound castor anti-yellowing agent.

Anti-yellowing agent is a chemical additive whose main function is to prevent the material from oxidizing under the action of light, heat or other external factors, thereby avoiding the phenomenon of yellowing. When this anti-yellowing agent is applied to high-resistance casters, it is like an invisible guardian, which not only delays the aging process of the casters, but also ensures its performance stability during use. This article will start from the performance of anti-yellowing agents in the rapid processing system, analyze its impact on the quality of the final product, and combine domestic and foreign literature data to present a comprehensive and vivid technical picture to readers.

Next, we will analyze the technical details in this field in an in-depth manner with easy-to-understand language and funny metaphors. Whether it is an industry expert or an ordinary reader, you can find content that you are interested in. So, let’s get started!

2. Basic principles of high rebound castor anti-yellowing agent

(I) What is an anti-yellowing agent?

Simply put, anti-yellowing agent is a chemical substance that can inhibit the oxidation reaction of the material. Imagine if you cut a fresh apple and put it in the air, it won’t take long to make its surface turn ugly yellow. This is because the phenolic compounds in apples react oxidatively with oxygen in the air. In plastic products, similar oxidation reactions can also cause the material to discolor, age, and even lose its original physical properties. At this time, the anti-yellowing agent is like an “antioxidation warrior”, protecting the material from damage by capturing free radicals or interrupting the oxidation chain reaction.

For high rebound casters, the importance of anti-yellowing agents is self-evident. Because casters are usually made of polymer materials such as polyurethane (PU), these materials are prone to free radicals during high-temperature processing, which in turn triggers an oxidation reaction. If effective protection measures are lacking, the following problems may occur:

  1. Appearance deterioration: The surface gradually turns yellow and loses its luster.
  2. Decreased mechanical properties: weakened elasticity and reduced wear resistance.
  3. Short service life>: It is more likely to damage in harsh environments.

Therefore, anti-yellowing agents have become an indispensable part of the production process of high rebound casters.

(II) Mechanism of action of anti-yellowing agent

The mechanism of action of anti-yellowing agents can be divided into the following aspects:

  1. Free Radical Capture
    Anti-yellowing agents prevent the propagation of oxidative chain reactions by capturing free radicals. This is like quickly extinguishing Mars in a fire scene to prevent the flame from spreading.

  2. Ultraviolet absorption
    Some anti-yellowing agents have ultraviolet absorption function and can effectively reduce the damage to the material by ultraviolet rays. It’s like putting a sunscreen on the caster so that it won’t deteriorate easily even if it is exposed to the sun for a long time.

  3. Metal ion passivation
    Certain metal ions catalyze the occurrence of oxidation reactions, and anti-yellowing agents can inactivate them by combining with these metal ions, thereby inhibiting the progress of oxidation reactions.

  4. Synergy Effect
    In practical applications, anti-yellowing agents often work in concert with other stabilizers (such as antioxidants, light stabilizers) to form a stronger protective barrier.

3. Product parameters of high rebound castor anti-yellowing agent

In order to better understand the application of anti-yellowing agents in high rebound casters, let’s first look at a set of typical product parameter tables:

parameter name Unit Typical value range Remarks
Appearance – White Powder Easy to disperse
Melting point ? 100-120 Ensure good processing fluidity
Molecular Weight g/mol 500-800 Influences dispersion and stability
Content (recommended addition) % 0.5-2.0 Adjust to specific needs
Heat resistance temperature ? >200 Adapting to high-temperature processing environment
Optical Stability – ?95% Prevent discoloration caused by ultraviolet rays
Compatibility – Good compatibility with PU materials Ensure even distribution

From the table above, it can be seen that all indicators of anti-yellowing agents have been carefully designed to meet the needs of high rebound casters under different processing conditions. For example, anti-yellowing agents with lower melting points are more likely to be incorporated into PU materials, while higher heat-resistant temperatures ensure their stability in high-temperature molding processes.

IV. Performance of anti-yellowing agents in rapid processing systems

(I) Characteristics of rapid processing system

Rapid processing system refers to an efficient and energy-saving production process, which usually includes the following characteristics:

  1. Short cycle: The entire production process is short and usually completed within a few minutes.
  2. High temperature and high pressure: The processing temperature may be as high as 150? or above, and the pressure is also relatively high.
  3. High degree of automation: Adopt advanced mechanical equipment and control systems to reduce manual intervention.

Under this system, the performance of anti-yellowing agents directly affects the quality and production efficiency of the product. Below we analyze its performance from several key dimensions.

(II) Dispersibility of anti-yellowing agents

In rapid processing systems, the dispersion of anti-yellowing agents is particularly important. If the dispersion is uneven, it may lead to poor anti-yellowing effect in local areas, which will cause spot-like yellowing during use. To this end, researchers have developed a series of improved methods, such as:

  1. Micropization treatment: Refine the anti-yellowing agent particles to the nanoscale to improve their dispersion.
  2. Premix technology: Fully mix the anti-yellowing agent with the substrate before production to form a uniform premix.

According to experimental data, the dispersion of the anti-yellowing agents treated above in the rapid processing system can be increased by 30%-50%. The following are the specific comparison results:

Processing Method Dispersible score (out of 10) Yellow Index Improvement Rate (%)
Original State 6 20
Microsizing 8 40
Premix technology 9 50

It can be seen that a reasonable treatment method can significantly improve the effect of the anti-yellowing agent.

(III) Heat resistance of anti-yellowing agents

The high temperature environment in the rapid processing system poses a serious challenge to the heat resistance of yellowing agents. If the anti-yellowing agent decomposes or fails at high temperatures, it will not only lead to waste of costs, but also affect the quality of the final product. Therefore, researchers have been working hard to develop anti-yellowing agents with stronger heat resistance.

In recent years, some new anti-yellowing agents (such as compounds based on benzotriazole structures) have attracted widespread attention for their excellent heat resistance. The following is a set of comparative experimental data:

Anti-yellowing agent type Heat resistance temperature (?) Yellowing index (?E) after processing
Traditional anti-yellowing agent 180 3.5
New anti-yellowing agent 220 1.2

From the data, it can be seen that the new anti-yellowing agent performs significantly better than traditional products at higher temperatures, which is particularly important for rapid processing systems.

5. Effect of anti-yellowing agent on final product quality

(I) Appearance quality

The intuitive function of anti-yellowing agent is to improve the appearance quality of the product. Just imagine that when you walk into a high-end furniture store, the casters you see are smooth and bright, rather than dull yellow, which will undoubtedly enhance your first impression of the entire product. In fact, studies have shown that the addition of anti-yellowing agent can reduce the caster’s yellowing index (?E) by more than 50%, thereby significantly extending its appearance retention period.

(II) Mechanical properties

In addition to appearance, anti-yellowing agents also have an important impact on the mechanical properties of casters. Because oxidation reaction will damage the inner part of polymer materialsThe component structure leads to a decrease in elasticity, hardness and wear resistance, so the protective effect of the anti-yellowing agent is particularly critical. The following is a set of experimental data showing the impact of anti-yellowing agent on casters’ mechanical properties:

Performance metrics No anti-yellowing agent Add anti-yellowing agent (0.5%) Improvement rate (%)
Elastic recovery rate (%) 70 85 21.4
Abrasion resistance (g) 0.5 0.3 40
Hardness variation (Shaw A) +5 ±0 -100

It can be seen from the table that the addition of anti-yellowing agent not only improves the elastic recovery ability of the casters, but also greatly reduces the amount of wear and almost completely eliminates the change in hardness.

(III) Service life

After

, anti-yellowing agent also plays an important role in extending the service life of the caster. According to a three-year tracking test, casters using anti-yellowing agents exhibited longer service life under the same conditions. The specific data are as follows:

User scenarios Life life of no anti-yellowing agent (years) A life span (years) of the added anti-yellowing agent Extend proportion (%)
Low indoor load 2 3 50
High outdoor load 1 2 100

Obviously, the presence of anti-yellowing agent allows casters to last longer in harsh environments.

6. Current status and development trends of domestic and foreign research

(I) Progress in foreign research

In foreign countries, the research on anti-yellowing agents has entered a more refined and diversified stage. For example, a well-known American chemical company has developed an anti-yellowing agent based on silicone, which not only has excellent anti-yellowing properties, but also gives the material better flexibilityand weather resistance. In addition, some research teams in Europe are exploring the introduction of bio-based materials into the field of anti-yellowing agents to achieve the goal of green and environmental protection.

(II) Domestic research trends

in the country, the research and development of anti-yellowing agents is also gradually advancing. In recent years, with the continuous increase in the country’s environmental protection requirements, many enterprises and scientific research institutions have begun to pay attention to the development of green anti-yellowing agents. For example, a university and a joint venture launched an anti-yellowing agent based on plant extracts, which maintains good performance while greatly reducing environmental pollution.

(III) Future development trends

Looking forward, the development of anti-yellowing agents will move towards the following directions:

  1. Multifunctionalization: Combining antioxidant, light stability and other functions to provide more comprehensive protection.
  2. Greenization: Use renewable resources as raw materials to reduce the impact on the environment.
  3. Intelligent: Use nanotechnology and intelligent responsive materials to achieve the function of release on demand.

7. Conclusion: The value and significance of anti-yellowing agent

Although high rebound castor anti-yellowing agent is only a small role, it plays a crucial role in the rapid processing system. From improving appearance to improving mechanical properties to extending service life, every contribution of anti-yellowing agents lays a solid foundation for the success of the final product. As the saying goes, “Details determine success or failure.” Anti-yellowing agents are one of those seemingly inconspicuous but indispensable details.
