CR

Neoprene rubbers are homopolymers of chloroprene (chlorobutadiene) and were among the first synthetic rubbers used to make gaskets.

Neoprene, or chloroprene (CR), is a successful synthetic elastomer produced by DuPont in 1931. It is prepared by emulsion polymerization of chloroprene or 2-chlorobutadiene. This material is used in many industries due to its resistance to chemicals such as ammonia and various coolants, oils and many other chemicals. Furthermore, neoprene O-rings have good resistance to sun, ozone and weathering, and have exceptional toughness.

Standard neoprenes are metal oxides and organic accelerators.

Combined with a wide temperature range and moderate cost, CR explains its desirability in many sealing applications for refrigerants such as Freon® and ammonia.

Neoprene O-rings also work well in contact with oils and many chemicals and have good resistance to sun, ozone and weathering. The material has exceptional toughness and good fire resistance. Neoprene O-rings are generally black in color, with a shelf life of 15 years, and have very low resistance to mineral oils.

​

Neoprene can be compounded for service temperatures from -40°C to +110°C (-40°F to +230°F).
