Neoprene is a synthetic rubber that is very commonly used to manufacture rubber gaskets and seals for a number of commercial and industrial processes. Based on polychloroprene, neoprene is a brand name developed by a chemical manufacturing company; it was developed as an oil-resistant alternative to natural rubber products. As many rubber gaskets and seals are subject to environments where they may come in direct contact with oils, neoprene is a suitable choice for such types of applications. Neoprene gaskets and seals have a wide range of beneficial properties:

  • Useful over a very wide range of temperatures
  • Resistant to tears or damage caused by twisting and/or flexing
  • Resistant to burning (much better than rubbers that are composed exclusively of hydrocarbon chains)
  • Resistance to many weather elements including ozone, ultraviolet light, sunlight, etc.
  • Resistant to natural and synthetic oils as well as other chemicals
