Hypalon derives from the chlorosulfonation of polyethylene. Crystalline polyethylene is made amorphous through the introduction of chlorine in amounts ranging from 25 to 45%. Different types of polymers characterized by variable chlorine content are available. The physical-mechanical characteristics, compression set, chemical resistance, and resistance to low temperatures are influenced by the chlorine content.
In general Hypalon is an elastomer used for a wide range of applications because of some of its peculiar characteristics such as:
