Chloroprene Rubber

CAS No.: 9010-98-4

Chloroprene Rubber (CR), also known as chlorobutadiene rubber, is an important polymer. The commercial grades are mostly trans-1,4-polychloroprene produced by free-radical emulsion polymerization of 2-chloro-1,3-butadiene.

Chloroprene Rubber is an important synthetic rubber. It is well balanced in physical properties, and has excellent light resistance, aging resistance, acid and alkali resistance, oil resistance, and heat resistance.

It is used in a wide range of applications, including automotive parts, belts, hoses, electric wires and cables, constructions, adhesives, and rubber gloves etc.

CR 244 series specification：It is similar to Denka A-90 and Dupont Neoprene AD-20.
