Chlorosulfonated Polyethylene

Chlorosulfonated Polyethylene
Chlorosulfonated Polyethylene
Chlorosulfonated polyethylene as CSM, is a vulcanized elastomer, having a completely saturated main chain and side groups ,and various of vulcanization methods can be used. Because of this structure, CSM vulcanizate has excellent property in ozone resistance, oxidation resistance and aging resistance. In addition, if suitably formulated, CSM vulcanizates will have excellent heat resistance, oil resistance, chemical resistance, and aging resistance.
