Once known by the trade name Hypalon®, Chlorosulfonated Polyethylene (CSM) compounds demonstrate excellent resistance to oxygen, ozone, heat and weathering.
Chlorosulfonated Polyethylene does have poor tear, abrasion resistance and compression set properties.
The operating temperature range for CSM is -65° to 275°F (-55° to 125°C). PAI offers CSM compounds in a hardness range of 50 to 80 durometer. Black is the standard color, but some white compounds are available.
