CSM 40 Chlorosulfonated Polyethylene Rubber Hypalon Rubber
Type
CSM 40, Tosho530, Hypalon CSM 40
Chemical Properties
1. CSM 40 rubber is a kind of off white, ordorless evenly rubber-shape, and it has the mutual character with rubber which also has its own property.
2. It is non-toxic, non-explosive, open flame burning, auto-extinction after removal.
3. It has excellent ozone resistance, resistance to atmospheric aging, chemical resistance, better physical mechanical, thermal aging resistance and low temperature resistance (-20℃-12℃), oil resistance, flame resistance, abrasion resistance and electrical insulation etc.
4. This rubber is a material with Neoprene Polychloroprene plus other qualities. The CSM rubber is suitable for continuous use up to about 130-degree Celsius. Chlorosulfonated polyethylene (CSM) is known for its excellent resistance to atmospheric conditions and good resistance to chemicals. Chlorosulfonated polyethylene is used in a variety of industrial and automotive applications that require high performance and have to withstand extreme weather conditions. Some products where chlorosulfonated polyethylene rubber is used include rubber linings, hoses, valve seals and gaskets etc.
