The origin and application characteristics of general rubber

General-purpose rubber has good comprehensive performance and wide application. Mainly: Shan natural rubber, from the three-leaf rubber latex system, the basic chemical composition is cis-poly isoprene. Good elasticity, high strength and good comprehensive performance. Shan isoprene Rubber, full name is Shun-1, 4-isoprene rubber, made by isoprene Gao type synthetic rubber, because of its structure and performance and natural rubber approximation, it is also known as synthetic natural rubber. Shan Styrene Butadiene Rubber, referred to as SBR, is made by copolymerization of butadiene and styrene. According to the production method, emulsion polymerization styrene-butadiene rubber and solution polymerization styrene-butadiene rubber. Its comprehensive performance and chemical stability are good. Shan BR, full name is cis-1, 4-polybutadiene rubber, referred to as BR, by butadiene polymerization system. and other general-purpose rubber ratio, vulcanized rubber after the cold resistance, wear resistance and elasticity is particularly good, dynamic load issued less heat, anti-aging performance, easy with natural rubber, neoprene, NBR and so on. Shan Neoprene, referred to as CR, is produced by polymerization of chloroprene. With good comprehensive performance, oil resistance, flame resistance, oxidation resistance and ozone resistance. But its density is bigger, the crystallization hardens at room temperature, the storage is not good, the cold resistance is poor.
