The role of rubber antioxidants

Rubber antioxidants are an important class of chemicals that play a protective role in rubber materials. These antioxidants prevent rubber from aging and oxidation under the influence of external factors such as air, heat, and light by blocking or delaying the reaction between oxygen and rubber molecules, thereby maintaining the elasticity, strength, and durability of rubber.

Main Function

1. Delaying aging: Antioxidants can effectively delay the aging process of rubber materials and increase the service life of the product.

2. Antioxidant: Antioxidants prevent the oxidative decomposition of rubber and maintain its physical properties by neutralizing the active molecules in oxygen.

3. Improve durability: By delaying aging and preventing oxidation, antioxidants enable rubber products to maintain good performance in various harsh environments.

Rubber Antioxidant Selection Guide

It is very important to choose the right rubber antioxidant according to different application requirements and environmental conditions. The following are several key factors to consider when choosing a rubber antioxidant:

1. Application areas

Different application fields have different requirements for rubber properties. For example, automobile tires require high wear resistance and oil resistance, while industrial seals pay more attention to anti-aging properties. Choosing appropriate antioxidants according to the application field can greatly improve the use effect of rubber products.

2. Operating Environment

The temperature, humidity, light and other factors of the environment in which the rubber product is placed will also affect the choice of antioxidant. In a high temperature environment, an antioxidant with stronger thermal stability should be selected; in a high humidity environment, a product with good water resistance should be considered.

3. Chemical stability

The chemical stability of the antioxidant itself is also an important factor to consider. It is necessary to ensure that the antioxidant will not degrade during the production and use of rubber products and lose its protective properties.

4. Environmental protection and safety

Choosing antioxidants that are environmentally friendly and safe not only ensures production safety, but also complies with increasingly stringent environmental regulations and helps improve the corporate image.

in conclusion

Rubber antioxidants play an indispensable role in preventing aging and oxidation of rubber materials and extending the service life of products. Choosing the right antioxidant can ensure that rubber products still maintain excellent performance in different environments, thereby improving the competitiveness of products. I hope the above selection guide can help you make more appropriate decisions in practical applications.
