클로로설폰화 폴리에틸렌 고무 chlorosulphonated polyethylene(CSM) 란?
폴리에틸렌에 염소와 아황산가스를 반응시켜, 가황 가능한 탄성체로 변화시켜 만든 합성고무의 일종.
금속산화물 등으로 가황되어 특히 내오존성, 내열성, 착색 안정성이 우수하다.
Hypalon®  
Hypalon®(하이파론)은 클로로썰폰화 폴리에틸렌 합성고무의 등록상표로 가황체는 내오존성, 내산소성, 내열성, 내후성, 내유성, 내후성 및 내약품성이 우수하며 장기산 외부 노출시도 변색치 않고 밝은 색상을 유지합니다. 또한 배합에 따라 우수한 기계적 특성, 높은 인장강도, 내마모성을 얻을 수 있습니다.
