Neoprene rubber is a highly useful polychloroprene synthetic rubber that has become an industry standard from all of its combined applications. Neoprene has critical toughness and maintains form over a larger temperature range than many other synthetic rubbers. Its tear strength, flex and resilience qualities are rated high. It has prime storage stability qualities and is non-peptizable. Neoprene polychloroprene rubber is used for water-based adhesives and solvent-based adhesives. Chemical resistance for neoprene is rated long-term. These all-around excellent qualities make neoprene the industry workhorse for synthetic rubbers. Besides its popular production in lineal roll sheets, neoprene can be produced in many dense qualities with added stiffness. It has formed several important applications rooting the auto industry. Sealing and gasket applications, floor pads, and bumpers are some of the obvious applications bringing improvement to the car industry. Other uses include fire protection applications such as boots and hoses; aquatic and waterproofing applications; liquid chemical resistances -- greases, mineral oils, light acids and alkalis; and outdoor weathering applications. In jewelry, neoprene has been formed into bracelets, and its music industry uses include neck straps for instruments. Neoprene was patented by the DuPont company, who frequently publishes elaborate manuals updating the rubber's uses.
