ASTM D 1418 Designation: CSM
ASTM D 2000, SAE J200 Type / Class: CE
STANDARD COLOR: Black
TRADE NAME: Hypalon

GENERAL TEMPERATURE RANGE: -20° to +250° F
Best known by the trade name Hypalon, chlorosulfonated polyethylenes are valued for their attractive combination of physical resilience and chemical resistance to corrosives, heat, oil, oxygen, ozone, and weather. Both heat resistance and low temperature flexibility can be augmented through use of lower amounts of chlorine, but oil resistance is only fair in such formulations. Higher chlorine levels lead to greater oil resistance at the expense of the heat resistance and low temperature flexibility. CSM can also be compounded to retain permanent bright colors. On the down side, CSM suffers from poor compression set resistance.
CSM PERFORMS WELL IN:
• Acids
• Alkalis
• Silicone oil & grease
• Water & water solvents
• Refrigerants (high chlorine compounding lends Freon resistance)
• Ozone
