High resilience castor anti-yellowing agent: a secret weapon to rejuvenate the wheels of office chairs

In a modern office environment, a comfortable chair is not only a right-hand assistant at work, but also an important element in showing personal taste and corporate image. However, after using it for a while, many people will find that the wheels of the originally shiny office chair gradually become dull and even embarrassing yellow spots. This not only affects the overall aesthetics, but may also make people mistakenly think that the equipment is aging or poor quality. So, is there a magical “potifer” that can re-bring the wheels of office chairs? The answer is yes – high rebound caster anti-yellowing agent is such a “secret weapon” that can significantly improve the appearance of office chair wheels.

What is a high rebound caster anti-yellowing agent?

Simply put, high rebound caster anti-yellowing agent is a functional additive designed specifically for plastic products (especially polyurethane materials). It can effectively suppress yellowing caused by ultraviolet irradiation, oxidation reaction or high-temperature environment, thereby maintaining the bright color and surface luster of the casters. This additive not only extends the service life of casters, but also keeps it fresh at the factory.

In order to more intuitively understand the characteristics of high-resistance castor anti-yellowing agent, we can compare the performance differences between traditional castors and anti-yellowing agents through the following table:

Parameters	Traditional castors	Castors after adding anti-yellowing agent
Color stability	Easy to light and turn yellow after long-term use	Strong anti-yellowing ability, maintaining the original color for a long time
Abrasion resistance	Fast wear and tear, easy to leave traces	Abrasion resistance is enhanced to reduce wear marks
Elasticity	The elasticity decreases significantly	Elasticity lasts, smoother scrolling
Heat resistance	It is easy to deform under high temperature	Heat resistance is improved and it is not easy to deform
Environmental	May contain harmful substances	Compare with international environmentGuaranteed standards, safe and non-toxic

From the above table, it can be seen that the application of high-resistance castor anti-yellowing agent not only improves the visual effect of castors, but also brings significant improvements in functionality and environmental protection. Next, we will explore in-depth the mechanism of this additive acting and how it can be used correctly to optimize the performance of office chair wheels.

Principle of action of high rebound castor anti-yellowing agent

To understand why high rebound casters anti-yellowing agents are so magical, we need to first understand the root cause of casters’ yellowing. Generally speaking, the main component of casters is polyurethane (PU), a polymer material with excellent mechanical properties. However, certain chemical bonds in polyurethanes, such as benzene ring structures, are very sensitive to UV and oxygen, and these chemical bonds break or recombination during long-term exposure to sunlight or high temperature environments, causing the material to degrade and appear yellow.

How does anti-yellowing agent work?

High rebound castor anti-yellowing agent prevents this process from happening through the following mechanisms:

Absorb UV rays
Anti-yellowing agents contain ultraviolet absorbers, which can convert the energy of ultraviolet rays into heat and dissipate them, thereby avoiding the direct effect of ultraviolet rays on the polyurethane molecular chains and reducing the probability of photochemical reactions.
Catch free radicals
During the oxidation process, polyurethane produces a large number of free radicals, which further destroy the material structure. The antioxidant components in the anti-yellowing agent can quickly capture and neutralize these free radicals, preventing the diffusion of the chain reaction.
Stable molecular structure
Certain anti-yellowing agents can also enhance the overall stability of the material and reduce the impact of external factors on it by forming covalent bonds or other chemical bonds with polyurethane molecules.
Prevent moisture invasion
Moisture is one of the important factors that accelerate material aging. The anti-yellowing agent can form a protective film on the surface of the caster to effectively isolate moisture penetration and thus delay the yellowing speed.

Progress in domestic and foreign research

In recent years, with the development of science and technology, domestic and foreign scholars have made many breakthroughs in the research on yelping agents. For example, DuPont, the United States, has developed a new nano-scale anti-yellowing agent with a particle size of only a few dozen nanometers and can be evenly dispersed in a polyurethane matrix, significantly improving the anti-yellowing effect. A study from Tsinghua University in China shows that by adjusting the proportion and addition of anti-yellowing agents, personalized needs can be achieved in different application scenariosbeg.

The following is a summary of data from some representative literature:

Literature Source	Main discoveries	Scope of application
DuPont Research Report	New nano anti-yellowing agent can extend the life of casters by more than 50%.	High-end office furniture and industrial equipment
Tsinghua University Papers	The anti-yellowing agents of different formulas are suitable for various temperature and humidity conditions	Widely used in civil and commercial fields
German BASF Experiment	After adding a specific proportion of anti-yellowing agent, the caster yellowing index will be reduced by 90%	Automotive interior parts and medical devices

Through these research results, we can see that high rebound caster anti-yellowing agent has developed from a single functional additive to a multi-dimensional, multi-functional solution.

Analysis of the advantages of high rebound castor anti-yellowing agent

Compared with traditional maintenance methods (such as regularly changing casters or using ordinary cleaners), high-resilience casters anti-yellowing agent has the following significant advantages:

1. Economic

While the cost of anti-yellowing agents is slightly higher than that of ordinary additives, in the long run, it can significantly extend the life of casters and reduce the additional expenses of frequent replacements. Take a company with 100 employees as an example. If each chair needs to be replaced once a year, the cost is about RMB 20 per unit, the total cost is RMB 2,000 per year. After using anti-yellowing agent, the caster life will be extended to two years or even longer, and only one-time investment will be required to save a lot of repair costs.

2. Environmental

Traditional casters are often difficult to degrade after being discarded, causing serious pollution to the environment. Casters treated with anti-yellowing agents are not only durable, but also meet the requirements of international environmental protection regulations such as RoHS and REACH, and truly achieve green production.

3. Easy operation

The method of using high rebound caster anti-yellowing agent is very simple. It only needs to be mixed into the raw materials in a certain proportion during the manufacturing process to complete the processing. For consumers, you can enjoy it with almost no extra operationGet high-quality product experience.

4. Enhance brand image

For corporate users, choosing an office chair with anti-yellowing function not only reflects attention to employee health, but also demonstrates the company’s sense of social responsibility and technical strength. Just imagine if clients walk into your office and see rows of neat and bright chairs, will their first impression of you be extra points?

How to correctly choose and use high rebound caster anti-yellowing agent?

Although the advantages of high rebound caster anti-yellowing agents are obvious, there are still some key points to be paid attention to in practical applications to ensure good results.

1. Clarify the needs

Select the appropriate anti-yellowing agent type according to the specific use scenario. For example, if office chairs are mainly placed in direct sunlight, products with strong UV protection capabilities should be given priority; while for areas with high humidity, moisture-proof performance should be paid attention to.

2. Control dosage

The amount of anti-yellowing agent added directly affects the final effect. Too little may lead to less obvious results, and too much may affect other performance indicators. The generally recommended addition ratio is 0.5%-2%, but the specific value needs to be adjusted in accordance with the actual situation.

3. Strict testing

Before mass production, be sure to conduct comprehensive testing of the samples, including but not limited to data recording of color changes, hardness, wear resistance, etc. Only by ensuring that all indicators meet the expected goals can we ensure stable and reliable product quality.

4. Last maintenance

Even if anti-yellowing agent is used, daily maintenance cannot be ignored. Regularly cleaning up dust and dirt on casters and avoiding long-term contact with corrosive liquids are effective measures to extend their service life.
