Chlorosulphonated Polyethylene Rubber (CSM) sheeting is known for its resistance to ozone and strong sunlight. You may also know this polymer by one of its brand names, such as Hypalon® (no longer available), Hailon, Lianda or TOSO-CSM®.
Chlorosulphonated polyethylene Rubber (CSM) is resistant to chromic, nitric, sulfuric and phosphoric acids and alkalis like chlorine dioxide, and hydrogen peroxide. CSM is often used in products which are in contact with sulfuric acid or nitric acid due to its excellent acid resistance. It’s resistance to acids and alkalis make it a great choice for chemical processing applications.
Chlorosulphonated polyethylene rubber also provides good fire resistance and is considered to be self-extinguishing. Its abrasion resistant properties combined with its fire resistance make CSM an excellent polymer for applications in mining operations.
