Hypalon

Trade Name: Hypalon - E.I. duPont de Nemours

The ethylene monomer with some of the hydrogen replaced by chlorine and sulphur groups is the main constituent of this elastomer.

It is useful over a temperature range of -65 to +250 degrees F (-54 to +121 degrees C) but its mechanical properties, compression and permanent set characteristics are less than is desired for both dynamic and static sealing applications.

Chlorosulfonated Polyethylene has good acid resistance.
