CSM (chlorosulphonated polyethylene rubber, hypalon)

This is a synthetic rubber used in the manufacture of voluminous products and it is obtained by processing polyethylene in a solution of chlorine and sulfur dioxide. It’s highly resistant to various weather conditions (UV, ozone, oxygen), water, acids and alkalis, chemicals, as well as to high and low temperatures. CSM is most commonly used in the production of snow shoes, increasingly replacing neoprene, because it is a lighter and a much more durable material.

Usage:

gaskets, membranes, molded products, inflatable boats.

Advantages:

• excellent resistance to oxidation, ozone, UV radiation, chemicals, acids, alkalis,
• non-flammable.

Disadvantages:

• bad compressibility
• permanent deformation if exposed to low and high temperatures.

Temperature resistance: from – 30 °C to 130 °C.

Hardness: 45 to 90 Shore A.
