General-purpose rubber has better overall performance and is widely used.
①Natural rubber. It is made from the latex of the para rubber tree, the basic chemical composition is cis-polyisoprene. Good elasticity, high strength, good overall performance
② Isoprene rubber. The full name is cis-1,4-polyisoprene rubber, a high-cis synthetic rubber made from isoprene. Because its structure and properties are similar to natural rubber, it is also called synthetic natural rubber
③ SBR. Abbreviated as SBR, it is made by copolymerization of butadiene and styrene. According to the production method, it is divided into emulsion polymerization styrene butadiene rubber and solution polymerization styrene butadiene rubber. Its comprehensive performance and chemical stability are good
④ Butadiene rubber. The full name is cis-1,4-polybutadiene rubber, abbreviated as BR, which is made by polymerization of butadiene. Compared with other general-purpose rubbers, vulcanized butadiene rubber has excellent cold resistance, abrasion resistance and elasticity, less heat under dynamic load, good aging resistance, and easy to use with natural rubber, neoprene rubber, nitrile rubber, etc. .
