Explanation

The synthesis methods of random copolymer of butadiene and styrene mainly include solution polymerization and emulsion polymerization, which are called solution styrene butadiene (SSBR) (styrene content 5% -40%) and emulsion styrene-butadiene rubber (styrene content 23.5% -25%), respectively. The physical and mechanical properties, processing properties and product use properties of styrene-butadiene rubber are close to natural rubber, and the wear resistance, heat resistance, aging resistance and vulcanization speed are better than natural rubber, It can be used together with natural rubber and a variety of synthetic rubber. It is widely used in the production of tires, tapes, hoses, wires and cables, medical appliances and various rubber products. It is the largest variety of general purpose synthetic rubber and one of the earliest rubber varieties to realize industrial production.
