What kind of rubber material does the tire use?
Styrene butadiene rubber (SBR), also called polystyrene butadiene copolymer. The performance of the physical mechanism, performance and processing performance of products is close to natural rubber, some properties such as wear resistance, heat resistance, aging resistance and curing rate is more excellent than natural rubber, and natural rubber and various synthetic rubber and other fields, widely used in the production of tires, rubber belt, rubber hose, wire and cable, and medical devices all kinds of rubber products, is the largest general synthetic rubber varieties, is the earliest one of the varieties of rubber industrial production.Ding Ji rubber is a synthetic rubber consisting of isobutene and a small amount of isoprene. They are commonly used in car tires and car noise proof products. Butyl rubber is now widely used as an environmental protection alternative to asphalt.
Polybutadiene rubber is cis polybutadiene rubber -1,4-, its molecular formula is n (C4H6). Polybutadiene rubber is synthetic rubber regular structure formed by the polymerization of butadiene, the CIS content of more than 95%. According to the different catalysts can be divided into nickel, cobalt, titanium and rare earth polybutadiene rubber (nd). Polybutadiene rubber is the second largest after the synthetic rubber sbr. Compared with natural rubber and styrene butadiene rubber, it is especially excellent in cold resistance, wear resistance and elasticity after vulcanization. It has less heat under the dynamic load and has good aging resistance. It is easy to use with natural rubber, chloroprene rubber or nitrile rubber. Polybutadiene rubber is especially suitable for the manufacture of automobile tires and cold products, also can produce cushioning materials and various rubber, adhesive tape, adhesive tape and sponge etc.
Natural rubber (NR) is a kind of natural polymer with CIS -1, 4- polyisoprene as the main component, the molecular formula is n (C5H8), the composition of 91% ~ 94% is rubber hydrocarbon (CIS -1, 4- polyisoprene), the protein, fatty acid, carbohydrate, ash and other non rubber substances. Natural rubber is the most widely used universal rubber.
The main material of automobile tire is the most widely used rubber, natural rubber, polybutadiene rubber, styrene butadiene rubber, rubber and other Ding Ji. Early automobile tires are outside the tire structure, wherein the inner tube is made of rubber, rubber and tire cord fabric made by multilayer. Nowadays tubeless tires are mostly radial tyres. Radial tire early steel strengthened, with the development of chemical technology, replaced by synthetic fiber steel radial gradually by Kevlar and other lighter weight, higher strength.
The tyre is known, usually made of rubber materials, a solid tire and pneumatic tire parts, pneumatic tyre and tubeless tire composed by.
