The Origin Of General Purpose Rubber And Its Application

Nov 30, 2016

General-purpose rubber comprehensive performance is better, widely used. Mainly: natural rubber, from the latex rubber tree system, the basic chemical composition of cis - polyisoprene. Elasticity, high strength, good overall performance. Isoprene rubber, the full name of cis-1,4-polyisoprene rubber, isoprene system of high cis-synthetic rubber, because of its structure and properties similar to natural rubber, it is also known as synthetic natural rubber. Styrene-butadiene rubber, referred to as SBR, from styrene and styrene copolymer system. According to the production method is divided into emulsion polymerization of styrene butadiene rubber and solution polymerization. Its comprehensive performance and chemical stability. Butadiene rubber, the full name of cis-1,4-polybutadiene rubber, referred to BR, by the polymerization of butadiene. With other general-purpose rubber, vulcanized cis-butadiene rubber cold resistance, abrasion resistance and flexibility are particularly excellent, less heat under the load, good aging resistance, and natural rubber, neoprene, nitrile rubber and other . Chloroprene rubber, referred to as CR, from chloroprene polymerization in the system. Has a good overall performance, oil resistance, flame resistance, oxidation resistance and ozone resistance. But its density is larger, easy to harden at room temperature, storage is not good, poor cold resistance.
