-1,4- is a cis polybutadiene rubber abbreviation, its molecular formula is (C4H6) n. Polybutadiene rubber is synthetic rubber regular structure formed by the polymerization of butadiene, the CIS structure content above 95%. According to the different catalysts, can be divided into nickel, cobalt, titanium and rare earth (nd) of polybutadiene rubber. Polybutadiene rubber is the second largest synthetic rubber after styrene butadiene rubber. Compared with the natural rubber and styrene butadiene rubber, vulcanized after its cold resistance, abrasion resistance and flexibility is particularly excellent dynamic load, less heat, aging resistance is good, easy and natural rubber, neoprene or nitrile rubber and. Polybutadiene rubber is especially suitable for the manufacture of automobile tires and cold products, but also can create the buffer material and all kinds of rubber overshoes, adhesive tape, adhesive tape and sponge rubber etc.
