It is an elastic polymer with good combination, low price and applying arrange wide. It can be blended with sulfuration PE, epichlorohydrin rubber, nitrile butadienen rubber, polyohloreprere rubber, styrene butadienen rubber and natural rubber etc.to manufacture various sulfuration products applied in middle & low pressures of wire and cable, leather etc. and as a synthetic rubber, it is also used to manufacture various sulfuration products, such as hose, rubber belt, magnetic rubber and water-proof color rolling profile. It can be used in blending of multiple plastics, such as PVC,PE,PP and ABS etc. to enhance their impact intensity, igniting resistant, cold resistant and oil resistant that suitable to produce foreskin of wire, jacket of cable, impact resistant pipe, sheet, profile and structural material etc.. It is grafting compounded with monomers of acrylonitrile, styrene, MMA etc. that can develop a series of engineering plastics with excellent properties.
