Hypalon (CSM) Rubber Sheet
Specified where exposure to oxidizing acids, UV radiation, and ozone occur simultaneously, conditions that eliminate EPDM, neoprene, and natural rubber from consideration. Chosen by chemical plant engineers, marine fabricators, and infrastructure contractors in 65+ countries.
What is a Hypalon (CSM / Chlorosulfonated) Rubber Sheet?
Hypalon is the industrial trade name for CSM, Chlorosulfonated Polyethylene, a synthetic elastomer originally developed and registered by DuPont. The technical polymer designation is CSM under ASTM D1418. It is manufactured for environments where ozone exposure, UV radiation, & chemical aggression occur in combination: conditions that degrade EPDM, neoprene, & standard rubber compounds within months.
The chlorosulfonyl groups in the polymer backbone give Hypalon rubber its defining property: resistance to oxidizing acids, including nitric acid and sulfuric acid, at concentrations where most elastomers swell and lose tensile strength. Combined with near-complete UV and ozone immunity, this makes Hypalon the specification standard for outdoor chemical containment, marine lining, flue gas systems, etc.
Duratuf Hypalon sheets are supplied as 100% CSM compound. No blended or diluted formulations. Operating range: -30°C to +130°C, with smooth plain finish on both sides for sealing and lining applications.
- Chemical tank and vessel lining in acid-handling plants
- Flue gas duct lining and exhaust system components
- Outdoor expansion joints and weatherproof sealing
- Marine deck covering and hull lining applications

Key Features of Duratuf Chlorosulfonated (Hypalon Rubber) Sheets
Duratuf Hypalon sheets are designed to deliver performance in harsh environments, where there is constant chemical exposure. Some features of our Hypalon rubber sheets are:
Resists nitric acid, sulfuric acid, and chromic acid at concentrations that destroy EPDM, neoprene, and nitrile, the primary specification driver for chemical containment duty.
The CSM polymer backbone is inherently resistant to UV radiation and ozone attack. No surface cracking or hardness shift under continuous outdoor exposure unlike NR, SBR, and neoprene.
Maintains sealing integrity and mechanical properties across a wide thermal range, suitable for both outdoor cold-climate service and moderate industrial heat duty.
Free from restricted and hazardous substances. Batch certificates and compliance documentation available with every shipment for regulated procurement requirements.
When you buy Duratuf rubber sheets, you invest in productivity and performance equally.
