The Source and Application Characteristics of Universal Rubber

Universal rubber has good comprehensive performance and is widely used. Mainly including: ① Natural rubber, obtained from latex from rubber trees with three leaves, and its basic chemical composition is cis polyisoprene. Good elasticity, high strength, and good overall performance Isoprene rubber, also known as cis-1,4-polyisoprene rubber, is a highly cis synthetic rubber made from isoprene. Due to its similar structure and properties to natural rubber, it is also known as synthetic natural rubber Styrene butadiene rubber, abbreviated as SBR, is obtained by copolymerization of butadiene and styrene. According to the production method, it can be divided into lotion polymerized styrene butadiene rubber and solution polymerized styrene butadiene rubber. Its comprehensive performance and chemical stability are good. ④ Cis-1,4-polybutadiene rubber, also known as BR, is synthesized by polymerization of butadiene. Compared with other general-purpose rubbers, vulcanized polybutadiene rubber has excellent cold resistance, wear resistance, and elasticity. It generates less heat under dynamic load and has good aging resistance. It is easy to mix with natural rubber, chloroprene rubber, nitrile rubber, etc Chloroprene rubber, abbreviated as CR, is produced by polymerization of chloroprene. Having good qualities
