Chlorosulfonated Polyethylene

Chlorosulfonated Polyethylene (CSM)/Hypalon®

Chlorosulfonated polyethylene is the base polymer for CSM synthetic rubbers.

Chlorosulfonated polyethylene compounds provide excellent ozone, oxidation, sunlight (color degradation), and weather resistance. They are also capable of providing excellent resistance to alkalis and acids.

Compound 399ES, 399BL

  • Acid resistant, “general purpose” type elastomers
