SPEC SHEET: Chloroprene Rubber (CR) 70 Durometer

Chloroprene Rubber (CR)

Material Description

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. CR is a multi-purposed elastomer which yields a balanced combination of properties. It performs well in contact with oils and many chemicals and has good resistance to sun, ozone and weather. It also displays outstanding toughness and good resistance to fire.

Cure system: Sulfur-cured

Standard CRs are metal oxides and organic accelerators.

Temperature Range:

Standard Low Temp: -40°C (-40°F)

Standard High Temp: 100°C (212°F)
