The definition and working principle of rubber anti-degradation agent

Rubber antidegradants are a class of chemicals designed to protect rubber materials from environmental factors such as oxygen, ozone and heat, thereby extending their service life. They slow down the degradation of rubber materials by trapping free radicals, absorbing ultraviolet light, and other mechanisms.

Effect of improving the durability and performance of natural rubber

The durability of natural rubber has been significantly improved after the application of rubber anti-degradation agents. According to experimental data, the life of natural rubber containing anti-degradation agents can be extended by more than 30% when exposed to ultraviolet rays and oxygen.

Different types of anti-degradation agents and their applicable scenarios

Rubber anti-degradation agents are mainly divided into three categories: antioxidants, light stabilizers and heat stabilizers. Antioxidants are mainly used to prevent oxidation of rubber in high-temperature environments; light stabilizers have excellent effects against ultraviolet rays; heat stabilizers are mainly used under high-temperature conditions to ensure stable rubber performance. Each type of antidegradant has its advantages and disadvantages in specific application scenarios. The details are shown in Chart 1:

in conclusion

Rubber anti-degradation agents are of great significance in natural rubber applications. By choosing the right anti-degradation agent, the durability and performance of rubber products can be significantly improved, resulting in economic benefits.
