High resilience castor anti-yellowing agent: definition and mechanism of action

What is a high rebound caster anti-yellowing agent?

High rebound caster anti-yellowing agent is a chemical additive specially used to improve the anti-yellowing properties of caster materials (such as rubber, polyurethane, etc.). Simply put, its task is to keep the casters’ original color and appearance during long-term use, and avoid yellowing caused by factors such as ultraviolet rays, oxidation or high temperatures. This not only improves the aesthetics of the product, but also extends the service life of the casters.

To understand the mechanism of action of anti-yellowing agents, you first need to understand why casters turn yellow. Typically, certain components in caster materials (such as unsaturated bonds or aromatic compounds) are susceptible to external environmental factors, and undergo molecular structure changes, resulting in yellow substances. Anti-yellowing agents effectively inhibit the occurrence of yellowing by intervening in these reaction processes.

Mechanism of action of anti-yellowing agent

The main functions of anti-yellowing agents can be summarized as follows:

Absorb UV rays
Ultraviolet rays are one of the main reasons for yellowing of casters. The light stabilizer in the anti-yellowing agent absorbs UV energy and converts it into harmless heat energy to release it, thereby protecting the surface of the caster from UV erosion.
Catch free radicals
During the oxidation process, free radicals are the culprits that destroy the molecular structure. Antioxidants in anti-yellowing agents can quickly capture and neutralize free radicals, preventing the occurrence of chain reactions, thereby reducing the aging rate of the material.
Shield harmful gases
Dangerous gases such as nitrogen dioxide and ozone present in certain industrial environments can also accelerate the yellowing of casters. The anti-yellowing agent further reduces the risk of yellowing by forming a protective film that isolates the contact between these gases and caster materials.
Improving heat resistance
High temperature environments may cause changes in the internal structure of casters materials, which in turn causes yellowing. Anti-yellowing agents can enhance the heat resistance of the material by regulating the interaction between molecules, so that it remains stable under high temperature conditions.

In order to more intuitively demonstrate the effect of anti-yellowing agents, we can refer to the experimental data comparison in the following table:

Test conditions	Ordinary Casters	Castors with anti-yellowing agent
Color change after 500 hours of ultraviolet ray irradiation (ΔE)	8.7	2.3
High temperature (80°C) treatment after 7 days (Shao Brothers A)	-15%	+2%
Time of occurrence of surface cracks in ozone environment (hours)	48	>300

It can be seen from the table that casters with anti-yellowing agents have shown significant advantages in all tests, proving their effectiveness in practical applications.

Detailed explanation of technical parameters: Core indicators of high rebound castor anti-yellowing agent

Since anti-yellowing agents are so important, what are their technical parameters? The following are several key indicators and their significance:

1. Absorption wavelength range

The absorption wavelength range of the anti-yellowing agent determines its protection against ultraviolet rays. Generally speaking, high-quality anti-yellowing agents can efficiently absorb UV rays in the wavelength range of 290-400nm, ensuring that the casters can maintain a good appearance under direct sunlight.

parameter name	Unit	Value
Large absorption wavelength	nm	360
Absorption efficiency	%	≥95

2. Antioxidant capacity

Antioxidation ability is a key indicator to measure whether anti-yellowing agents can effectively capture free radicals. It is usually expressed by half-life, that is, the longer it takes for the anti-yellowing agent to consume half of the time under specific conditions, the stronger its antioxidant capacity.

parameter name	Unit	value
Half-life (at 120°C)	hours	>500

3. Heat resistance

Heat resistance reflects the stability of the anti-yellowing agent in high temperature environments. If the anti-yellowing agent itself cannot withstand high temperatures, its protective effect will naturally be greatly reduced.

parameter name	Unit	value
Decomposition temperature	°C	>280
Large operating temperature	°C	150

4. Compatibility

Compatibility refers to the degree of matching between the anti-yellowing agent and the caster material. The anti-yellowing agent can only be fully exerted when it is evenly dispersed in the material.

parameter name	Description
Compatibility with polyurethane	Good
Compatibility with natural rubber	Medium

The above parameters together constitute the technical basis for anti-yellowing agents and provide manufacturers with a basis for choosing suitable products.

Current application status:Performance of high rebound caster anti-yellowing agent in different fields

Although anti-yellowing agents may sound a bit abstract, they are very widespread in practical applications. Let’s take a look at some typical examples:

1. Industrial field

In industrial environments, casters often need to withstand high-intensity workloads, while also facing complex external conditions such as ultraviolet radiation and high temperatures. Therefore, industrial casters have extremely high requirements for material performance. Research shows that casters made of polyurethane materials containing anti-yellowing agents can last 30%-50% longer than ordinary casters, and always maintain excellent appearance and performance throughout their life cycle.

2. Medical field

Castors in medical equipment not only meet basic mobile needs, but also have high cleanliness and durability. Since disinfection procedures in the hospital may release corrosive gases, caster materials must have strong resistance to yellowing. In this context, the application of anti-yellowing agents is particularly important. Data show that after two consecutive years of use, the surface of medical casters that have been treated with anti-yellowing is still as smooth as new, without any obvious yellowing or cracks.

3. Logistics and Warehousing

Castors in the logistics industry pay more attention to wear resistance and shock absorption. The high-resistance castor anti-yellowing agent can not only improve the material’s anti-yellowing performance, but also optimize its elastic modulus, making the castors more stable and quiet during the rolling process. This is of great significance to reducing noise pollution and improving work efficiency.
