What is CSM chemical?

What is CSM chemical?

Chlorosulphonated Polyethylene Rubber (CSM) sheeting is known for its resistance to ozone and strong sunlight. You may also know this polymer by one of its brand names, such as Hypalon® (no longer available), Hailon, Lianda or TOSO-CSM®.

What is CSM material?

Chlorosulfonated polyethylene or CSM is a synthetic rubber based on polyethylene. This rubber is a material with Neoprene Polychloroprene plus other qualities. Chlorosulfonated polyethylene (CSM) is known for its excellent resistance to atmospheric conditions and good resistance to chemicals.

What is Hypalon made of?

Hypalon was a chlorosulfonated polyethylene (CSPE) synthetic rubber (CSM) noted for its resistance to chemicals, temperature extremes, and ultraviolet light. It was a product of DuPont Performance Elastomers, a subsidiary of DuPont.

What is CR rubber?

Chloroprene rubber (CR) is a synthetic rubber that is also known by the trade name Neoprene. CR has a good balance of properties, including good chemical stability and usefulness over a wide temperature range.

How is chlorosulfonated polyethylene made?

Chlorosulfonated polyethylene is a family of chlorinated elastomers. The materials is made by reacting polyethylene with chlorine and sulfur dioxide to yield chlorosul-fonated polyethylene. The reaction changes the thermoplastic polyethylene into a synthetic elastomer that can be compounded and vulcanised.

Is CSM the same as Hypalon?

About PVC & ORCA® CSM (Hypalon) Hypalon was discontinued by its manufacturer (DuPont) and is now sold under its slightly different formula and new name “CSM” or Chlorosulfonated Polyethylene Rubber.

Is Hypalon still available?

Hypalon was discontinued by its manufacturer (DuPont) and is now sold under its slightly different formula and new name “CSM” or Chlorosulfonated Polyethylene Rubber.

What is neoprene CR?

Neoprene was the first synthetic rubber developed commercially and exhibits generally good ozone, aging and chemical resistance. It has good mechanical properties over a wide temperature range. Both o-rings and gaskets can be made from Neoprene materials. …

Is chloroprene and neoprene same?

Neoprene is the common name for the polymers of chloroprene (2-chloro-1,3-butadiene). These are produced by emulsion polymerization.

What is chlorosulfonated polyethylene rubber?

Some poducts where chlorosulfonated polyethylene rubber is used include rubber linings, hoses, valve seals and gaskets etc. Hypalon® is the trade mark of CSM. Hypalon was developed in 1951 and since then it has become the common name for chlorosulfonated polyethylene.

Why choose chlorosulfonated polyethylene (CSM)?

Good dynamic properties and outstanding adhesion to substrates such as fabrics and brass coated steel make Chlorosulfonated Polyethylene (CSM) a unique choice for hose and belting.

What is the temperature range for chlorosulfonated polyethylene?

Chlorosulfonated Polyethylene. Such rubbers have high resistance to wear and repeated deformation. The temperature range for their most efficient use is –60° to 180°C. Chlorosulfonated polyethylene made from high-density polyethylene may also be used in unvulcanized form.

What is CSM in chloroprene?

Chlorosulfonated polyethylene (CSM, CSPE) is widely known as Hypalon ®. 1 It can be considered a superior type of chloroprene, having better heat and chemical resistance. CSM grades usually contain 20 – 45 percent chlorine which provides excellent resistance to ozone, UV, weathering, and chemicals.
