Next, please follow our pace and explore this technological revolution in the field of casters together!

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

(I) What are high rebound casters?

High rebound casters are casters made of special elastic materials. Their main features are excellent rebound performance and shock absorption. Compared with traditional casters, high rebound casters can quickly return to their original state when under high pressure, thereby significantly improving service life and user experience. For example, in industrial environments, such casters can better adapt to uneven ground and reduce vibration during equipment operation; while in home scenarios, they can provide a more stable and comfortable mobile experience.

However, although high rebound casters have many advantages, their surface materials (such as TPUs, PUs, etc.) are prone to yellowing when exposed to ultraviolet rays or high temperatures for a long time. This change not only destroys the overall aesthetic of the product, but may also lead to a decline in material performance, which in turn affects the normal use of casters.

(II) Principle of action of anti-yellowing agent

Anti-yellowing agent is a chemical additive, specially used to inhibit or delay the tendency of yellowing caused by external factors of the material. Specifically, it works in the following ways:

Absorb UV rays: Anti-yellowing agents can absorb ultraviolet radiation from sunlight or other light sources, converting it into heat energy to emit it, thereby avoiding the damage to the molecular structure of the material by ultraviolet rays.
Catch free radicals: When the material is subject to oxidation, a large number of free radicals will be generated, which will accelerate the occurrence of yellowing. Anti-yellowing agents can prevent further chemical reactions by capturing these free radicals.
Stable molecular structure: Some anti-yellowing agents can also directly participate in chemical reactions inside the material, enhance the stability of the molecular chain and reduce color changes caused by aging.

Simply put, the anti-yellowing agent is like a layer of invisible protective film, which puts a “anti-old clothing” on the high-resistance casters, so that it can always maintain its original color and performance whether in the sun or in harsh environments.

3. Technical parameters and classification of high rebound caster anti-yellowing agent

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

(I) Household market: Create a suitcase that lasts as long as new

In recent years, with the booming development of tourism, consumers have also increasingly demanded for suitcases. A high-quality suitcase not only needs to be strong and durable, but also maintains long-term aesthetics. However, after using many traditional suitcases for a period of time, their casters will experience obvious yellowing, which seriously affects the overall visual effect.

In response to this problem, a well-known suitcase brand has introduced high rebound casters containing high-efficiency anti-yellowing agent. After a year of field testing, the results showed that the casters with anti-yellowing agent did not show any signs of yellowing even under the strong sunlight, and their rolling performance was still excellent. This improvement not only improves the competitiveness of the product, but also adds a lot of points to the brand image.

(II) Industrial field: Ensure the stable operation of equipment

In industrial production, casters are an indispensable part of many large-scale equipment. For example, on an automated assembly line, casters need to frequently carry heavy objects and move quickly, thus putting extremely high demands on the strength and stability of the material. However, since there are often more heat sources and chemicals in the workshop, ordinary casters are prone to yellowing or even deforming, resulting in frequent equipment failures.

To solve this problem, a leading industrial equipment manufacturer has added high-performance anti-yellowing agents to its new casters. After rigorous laboratory testing and on-site verification, this caster performed well and remained in its original state even after working for several months, which was highly praised by customers.

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

(I) Progress in foreign research

Around the world, European and American countries have started research on yelping agents early and have accumulated rich experience and achievements.

In addition, the composite anti-yellowing agent launched by BASF Group in Germany has also been widely praised. Its unique formula design makes the product have excellent antioxidant ability and low cost advantages.

It is worth mentioning that in recent years, foreign scholars have also begun to pay attention to the research and development of environmentally friendly anti-yellowing agents. They are trying to replace traditional chemicals with biodegradable materials to reduce potential harm to the environment. Although this type of product has not been commercialized on a large scale, its prospects are very broad.
