Price:
Chlorosulfonated polyethylene (CSM) is a special synthetic rubber prepared by chlorination and sulfonation of polyethylene at the same time. It has a fully saturated main chain and side group, and can be vulcanized by metal oxide, sulfur, polyol, peroxide and other vulcanization systems. It is suitable for vulcanization by various vulcanization molding methods. Because of this structure, CSM has many characteristics in the rubber industry, including:Excellent ozone resistance and weather resistance;Good resilience; Corrosion resistance to many chemicals; Moderate oil and solvent resistance;Good flame resistance; Excellent friction resistance and mechanical damage resistance.Specifications
