Description

A family of synthetic rubbers made by polymerizing chlorinated butadiene. Cchloroprene was first developed by DuPont in 1931 by Ira Williams and sold under the name of DuPrene in 1932. In 1936, DuPont changed its brand name to Neoprene; now neoprene is a generic term used for this class of synthetic rubbers. Neoprene is vulcanized with metal oxides rather than sulfur which makes it less elastic than rubber, but more resistant to chemicals, heat, and light. It is also resistant to water and biodegradation. Neoprene has a service temperature range of -50 to 95 C and has good compressibility. Neoprene is used for gaskets, roof coatings, shoe soles, wet suits, gloves, contact adhesives, and as a coating for fabrics.
