What is Hypalon made of?
Hypalon® is the DuPont® trademark for chlorosulfonated polyethylene (CSPE) synthetic rubber. It was a common high-performance material used for the insulation of wire and the jacketing of cable.
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.
What is CSM chemical?
Chlorosulphonated Polyethylene Rubber (CSM) sheeting is known for its resistance to ozone and strong sunlight. Chlorosulphonated polyethylene Rubber (CSM) is resistant to chromic, nitric, sulfuric and phosphoric acids and alkalis like chlorine dioxide, and hydrogen peroxide. …
What material is CSM?
Chlorosulfonated polyethylene
Chlorosulfonated polyethylene (CSM, CSPE) is widely known as Hypalon®. 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.
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. Coastal Boats are made with either PVC or Orca® CSM (Hypalon) from France. Each fabric has their advantages and disadvantages.
Is Hypalon still made?
What is CSM Hypalon?
Hypalon® Rubber is a brand name for the material Chlorosulfonated Polyethylene (CSM). This synthetic rubber is resistant to chemicals, weathering and water. It can handle temperature extremes and exposure to UV light. The brand name for this material was created by DuPont subsidiary DuPont Performance Elastomers.
What replaced 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 toxic?
For one, when Hypalon burns it releases highly toxic fumes. These fumes have been subjected to scrutiny in the polymers industry and considered to be an atmospheric pollutant. Moreover, Hypalon contains lead-based additives, well known for dangers and restrictions.
What is chlorosulfonated polymer give an example?
Commercial examples of chlorosulfonated polymer are chlorosulfonated polyethylenes sold under the trade name HYPALON® polymers (synthetic rubbers) by E. I. Du Pont de Nemours & Company of Wilmington, Del.
What is the role of chlorosulfonated polymers in acrylate adhesives?
In certain embodiments, the chlorosulfonated polymers, such as chlorosulfonated polyethylene, are used primarily as free radical initiators of the acrylate/methacrylate based adhesives described herein. As discussed below, secondary initiators, such as certain peroxides, may also be employed in addition to the chlorosulfonated polymer.
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.
Who are the manufacturers of chlorosulfonated polyethylene elastomers?
Two important manufacturers and suppliers of chlorosulfonated polyethylene elastomers are Tosoh and Lianda. 2 CSM elastomers are generally useful in electrical applications and as protective coatings against corrosive environments.
