Neoprene O-Rings

Chloroprene (CR), also known by its trade name “Neoprene”, was one of the first successful synthetic elastomers in 1931 made by DuPont. It is prepared by emulsion polymerization of chloroprene, or 2-chlorobutadiene.

Neoprene is a multi-purposed elastomer which yields a balanced combination of properties. Neoprene o-rings are typically seen in the refrigeration sector, as they demonstrate remarkable resistance to chemicals such as ammonia and a variety of coolants.

Neoprene o-rings also perform well in contact with oils and many chemicals and has good resistance to sun, ozone and weather. The material displays outstanding toughness and good resistance to fire.

Neoprene o-rings typically are black in color, with a shelf life of 15 years.
