CR sponge
All-purpose synthetic rubber used in wide-ranging sectors
CR stands for chloroprene rubber, which is a polymer consisting of butadiene rubber as a raw material. Characteristics include incombustibility, weather resistance, ozone-resistance, heat-resistant aging characteristics, oil resistance, and environmental degradation durability including chemical-resistance. Since CR posses versatile characteristics among special synthetic rubbers, it is used widely for many purposes as a material for vehicle and low-current, general industrial parts.
■ Main applications： insulation material, acoustic insulation, seals material, automobile parts, conveyer belt, anti-dust rubber, etc.
