Neoprene is the trade name for a family of synthetic rubbers based on polychloroprene. It is used in a wide variety of environments, such as in wetsuits, for electrical insulation, car fan belts; and due to its chemical inertness, in industrial applications such as gaskets, hoses, and corrosion-resistant coatings. It can also be used as a base for adhesives.

Polychloroprene is the polymer of chloroprene.
