Hypalon is a chlorosulfonated polyethylene (CSPE)- based synthetic rubber developed by DuPont in the early 1950's. There are various Hypalon elastomer types which are used in coatings, industrial cable, inflatable recreational crafts, single-ply roofing and geomembranes. Hypalon was introduced in he early 1960's and has been widley used in the geosynthetic industry as liners, caps and floating covers.
Hypalon is manufactured by a proprietary process in which two layers of CSPE compound are calendered to fully encapsulate a polyester reinforcing scrim. Hypalon Geomembranes exhibit thermoplastic qualities during processing and field installation, which permits seaming by chemical or thermal fusion methods. As the membrane is exposed to UV, weather and elements, it slowly cures into a vulcanized membrane, exhibiting a higher tensile strength.
