THE ENDLESS POSSIBILITIES OF RUBBER

Chlorosulphonated Polyethylene (CSM)

The rubber:

Also known as “Hypalon” by Dupont. CSM demonstrates durability in harsh environments and is known for its use in products that require high performance in extreme conditions (such as extreme temperatures, and ultra violet light, but also resistance to chemicals, etc.).

Resistance and properties:

This rubber has excellent resistance to oxygen, water, oil, acid, ozone and many chemicals. The physical qualities are excellent. Also high temperature resistance is good (up to + 130 degrees Celsius) as are the abrasion properties. CSM has strong flame retardant properties and the gas density is good.

Downsides:CSM has poor compression set and poor fuel resistance.
Applications:CSM is widely used, from shoe soles to coatings, flexible tubes, seals and gaskets.
