Chlorosulfonated polyethylene (CSM)

Chlorosulfonated Polyethylene(CSM)

Chlorosulfonated polyethylene (CSM)

Chlorosulfonated polyethylene referred to as CSM is a special synthetic rubber which has completely saturated main chain and pendant group. It is suitable for vulcanization by various vulcanization molding methods and can be vulcanized by all kind of cross linking agent, like metal oxide, sulfur, polyol, peroxide and so on.

Also the unique molecular structure give CSM vulcanizate the excellent ozone resistance , weather resistance and great resistance to heat, oil, chemicals and aging with properly formulated CSM vulcanizate in rubber production.
