HYPALON® (CSM) Chlorosulfonated Polyethylene

HYPALON® (CSM) Chlorosulfonated Polyethylene

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:

  • good behavior in a wide range of temperatures (from -40 to +140°C);
  • excellent mechanical characteristics;
  • excellent resistance to ozone, weather and heat;
  • excellent chemical resistance, in particular to oxidizing and corrosive agents;
  • excellent resistance to seawater and saline solutions;
  • good resistance to acids and strong mineral bases, hypochlorites and alcohols;
  • low permeability to moisture and other vapors, air and gas;
  • excellent resistance to flame;
  • good dielectric characteristics.
