According to the traditional classification method(effect of different), rubber additives are generally divided into the six categories.
Categories 1: vulcanization system auxiliary agent, mainly has the vulcanization agent, the accelerator and the activator.
Categories 2: protection system additives, mainly anti-aging agents and flame retardants.
Categories 3: operating system additives, mainly plasticizers (softeners), dispersants, homogenizers, viscosity enhancers, mold release agents and anti-coke agents.
Categories 4: reinforcing filler system additives, mainly carbon black, white carton black, etc.
Categories 5: adhesion system additives, mainly cobalt salt adhesion accelerator..
Categories 6: other auxiliaries, including colorants, foaming agents, defoaming agents, thickening agents, etc.
The upstream raw materials of rubber auxiliary products are mainly various petrochemical products and related chemical intermediates, the main raw materials include aniline, carbon disulfide, cyclohexylamine, tert-butylamine, dimethylamine, hydrogen peroxide, morpholine and so on.
More than 80% of the application of rubber additives relating to automotive, 70% of rubber additives output are used for tire production. Take the automobile as an example, there are nearly 200 kinds of rubber products for an automobile, including tires, seat cushions, door and window sealing strips, wiper strips, fan belts, water tank hose, brake hose, dust jacket, various seals, shock absorbers and so on. Automobile and tire consumption presents a new development trend of medium and low speed growth, which will be the “new normal” of the development of automobile and tire industry at present and in the next few years.
