(1) Anti-aging agent The main function of the anti-aging agent is to block the rubber and its products from being subjected to heat, oxygen, ozone, variable valence metal ions, mechanical stress, light and high energy during long-term storage and use. The damage of the surface of the rubber compound by factors such as rays, as well as the erosion of other chemicals and molds, thus prolonging the storage period and service life of rubber and its products. 

(2) Anti-Reversion Agent Anti-reversion agent is a new type of rubber additive specially used to improve the anti-reversion of vulcanized rubber. It has the advantages of protecting the stability of the vulcanization network, improving the thermal oxygen stability of the product, and maintaining the good dynamic performance of the ordinary vulcanization system and the semi-effective vulcanization system. Therefore, the anti-reversion agent can be regarded as a new additive for the vulcanization system, and can also be regarded as a new additive for the anti-aging system.
