Chlorinated Polyethylene (CM) is derived by the random chlorination of high density polyethylene. It demonstrates resistance to ozone, weather, acids and bases. This polymer has reasonable resistance to petroleum based oils.

The operating temperature range for CM materials is -50º to 300ºF (-45º to 150ºC). PAI has a 80 durometer black Chlorinated Polyethylene compound, but will develop others upon request.
