Synthetic rubber according to different rubber synthesis of different raw materials, mainly divided into four kinds:: 1, styrene butadiene rubber: raw materials are butadiene and styrene.
1.styrene butadiene rubber: raw materials are butadiene and styrene. Styrene-butadiene rubber is the largest production of general-purpose synthetic rubber.
2.Sunbutadiene rubber: raw material is butadiene. The male butadiene rubber has particularly excellent cold resistance, abrasion resistance and elasticity, but also has a good aging resistance. The vast majority of the male rubber used in the production of tires, a small portion used in the manufacture of cold products, cushioning materials, as well as adhesive tape, rubber shoes and so on. The shortcomings of cis-butadiene rubber is poor tear resistance, anti-slippery performance is not good.
3.isoprene rubber: raw material is isoprene. Produced using solution polymerization method, isoprene rubber and natural rubber, with good elasticity and abrasion resistance, excellent heat resistance and good chemical stability. The strength of raw (unprocessed) isoprene rubber is significantly lower than that of natural rubber, but the quality uniformity and processing performance are better than that of natural rubber. Isoprene rubber can replace natural rubber manufacturing heavy-duty tires and cross-country tires can also be used to produce a variety of rubber products.
4.ethylene propylene rubber: the main raw material is ethylene and propylene. Aging resistance, electrical insulation properties and ozone resistance is outstanding. Ethylene propylene synthetic rubber rubber can be a large number of oil-filled and filled with carbon black, products with lower prices, ethylene propylene rubber chemical stability, abrasion resistance, elasticity, oil resistance and styrene-butadiene rubber close.
