Chlorosulfonated Polyethylene (CSM)

Vulcanized forms of chlorosulfonated polyethylene are highly resistant to the deteriorating effects of ozone, oxygen, weather, heat, oil and chemicals.


They resist discoloration on exposure to light, and are widely used in light- colored products. CSM can be compounded to provide excellent mechanical properties. (Ex: high tensile strength and abrasion resistance)

  • Permanent bright colors
  • Superb ozone and weather resistance, even in non-black products
  • Heat resistant to 150°C
  • Resistance to a wide range of aggressive chemicals
  • Intermediate oil and solvent resistance depending on the chlorine level
  • Electrical insulating properties
  • Low flammability characteristics (associated with chlorinated polymers)
  • Excellent resistance to abrasion and mechanical abuse
  • Automotive hoses, gaskets and flexible tubes
  • Gas and industrial applications
  • Electric cable jacketing
  • Floor tiles
  • Rubber coated cloth
  • Escalator handrails
  • Inflatable boats and folding kayaks
