Rubber additives are used to give rubber products performance, to ensure the service life of rubber products, to improve the processing performance of rubber compound a series of fine chemical products. Rubber additives and rubber rubber rubber through the scientific ratio, can give rubber products, high strength, high elasticity, aging resistance, abrasion resistance, high temperature resistance, low temperature resistance, noise reduction and other properties. Rubber additives industry is usually divided into five categories of products, namely: rubber accelerators, rubber antioxidants, vulcanizing agents and vulcanization activators, special functional additives and processing aids. Among them, accelerators, antioxidants and vulcanizing agents are general rubber product additives, also called general-purpose rubber additives; corresponding to the special rubber additives, including functional rubber additives and processing rubber additives two categories.
1、Rubber chemicals industry chain
The upstream raw materials of rubber auxiliaries mainly come from the basic chemical industry such as salt chemical industry, coal chemical industry and petrochemical industry, mainly cyclohexane, phthalic anhydride, aniline, tert-butyl amine, fatty acid, zinc oxide, wax and so on. Midstream for all kinds of rubber auxiliaries, mainly rubber accelerator, rubber antioxidant, vulcanizing agent and vulcanization activator, special functional additives and processing aids. The downstream of rubber chemicals are all kinds of rubber products, including tires, rubber hoses, rubber belts, rubber sheets, rubber shoe soles, seals and so on.
2、Rubber additives downstream application analysis
According to the data of China Rubber Industry Association, nearly 90% of rubber auxiliary applications in the rubber auxiliary industry are related to automobiles, and about 70% of the demand is used for tire production.
The future development trend of rubber chemicals industry
1, high-end, intelligent, green as the direction of development
Tires and rubber products is an important basic industry of the national economy, rubber chemicals is the whole tire and rubber products processing performance and application performance of the cornerstone of the industry recognized that "there is no rubber chemicals on the modern rubber industry". China's rubber chemicals industry in the high-end, green and intelligent research and development started late, China Rubber Industry Association will "develop green chemical, breakthroughs in key technologies, to create a world power in the rubber chemicals industry" as the industry's important policy, the National "14th Five-Year Plan The national "14th Five-Year Plan" also puts forward the in-depth implementation of intelligent manufacturing and green manufacturing projects, the development of new modes of service-oriented manufacturing, and promote high-end manufacturing, intelligence, greening, and optimization and upgrading of the manufacturing industry.
2、Industry development is good, industry concentration continues to improve
China's rubber chemicals industry market size continues to expand at the same time, the market concentration continues to improve, industry development opportunities continue to large-scale chemicals manufacturers converge. 2020, the rubber chemicals industry, the top ten enterprises according to sales revenue calculation of the industry concentration of up to 66.3%, the market share of large-scale rubber chemicals companies have gradually increased, backward production capacity of small-scale rubber chemicals enterprises gradually eliminated by the market.
