Rubber antioxidant is a kind of chemical added in the process of rubber production, which can delay the aging of rubber and prolong the service life of rubber. According to its main functions, it can be divided into anti thermal oxygen aging agent, anti ozone agent, harmful metal ion inhibitor, anti fatigue agent, ultraviolet absorber, anti cracking agent, etc.

With the eastward movement of the global rubber industry, especially the production bases of the global tire industry have successively moved to Asia, the rubber additive industry has ushered in a historic development opportunity. China is the world's largest producer and supplier of rubber additives, and plays an important role in the world. In 2021, the output of rubber additives in China reached 1.37 million tons, of which rubber antioxidant accounted for 30%.

In 2021, the output of natural rubber and synthetic rubber in China increased compared with that in 2020. Among them, the output of natural rubber increased by 23%, resulting in a significant increase in the output of rubber antioxidant. In 2021, the output of rubber antioxidant in China was 415000 tons, an increase of 13% over the same period in 2020.

In the past six years, the average demand for rubber accelerator is 360000 tons. In 2021, the demand for rubber antioxidant is 401000 tons, an increase of 45000 tons over 2020.
