Neoprene or polychloroprene is a family of synthetic rubbers produced by polymerization of chloroprene. Neoprene is the DuPont trade name for its brand of polychloroprene.
Good compression set resistance, good resilience and resistant to abrasion.
Neoprene rubber is classified as a general purpose elastomer with good compression set resistance, good resilience and the ability to resist abrasion and flex cracking over a wide range of temperatures. Neoprene rubber adheres well to metals for rubber to metal bonding applications. Because neoprene rubber is very resistant to Freon and ammonia it is widely used for sealing refrigeration fluids.
Used for automotive fan belts, insulation material and waterproof automotive seat covers.
Neoprene rubber is used in a wide variety of applications, such as laptop sleeves, orthopedic braces (wrist, knee, etc.), electrical insulation, liquid and sheet applied elastomeric membranes or flashings and automotive fan belts. A foamed neoprene containing gas cells is used as an insulation material, most notably in wetsuits and fly-fishing waders. Other foamed neoprene applications include insulation and shock-protection (such as packing).
Neoprene rubber is used in many industrial applications, from face protection masks, waterproof automotive seat covers to insulation for CPU sockets. As a liquid or sheet, neoprene rubber is used for roof membranes or flashings. As a neoprene-spandex mixture it is used in wheelchair positioning harness manufacturing.
