Polychloroprene rubber or neoprene has more than 75 years of proven performance in varied industrial applications. Neoprene, an extremely useful synthetic rubber, is the DuPont Performance Elastomer's trade name for a family of polychloroprene rubber (CR). In other words, polychloroprene is the polymer name for the synthetic rubber known as neoprene. This rubber was developed in 1931 and supposed to be the first specialty elastomer. This is one of the most important types of synthetic rubber with an annual consumption of nearly 300000 tons worldwide. Polychloroprene rubber has a perfect balance of mechanical properties and fatigue resistance which is second only to natural rubber. Neoprene rubber also has superior oil, chemical and heat resistance. This type of rubber (Polychloroprene rubber or Neoprene) is widely used in general engineering applications.
