What is Neoprene Rubber? General Properties, Compatibility & More

Also known as polychloroprene or chloroprene rubber, neoprene is a type of synthetic rubber. It exhibits good chemical stability and excellent flexibility, which it maintains at extreme temperatures (from -45° to 225°F/-43° to 107°C).

Neoprene o-rings, gaskets, and seals are weather, combustion, water, and chemical resistant, and impermeable to fluids and gases. It also resists degradation better than natural or standard synthetic rubber and is relatively inert. These properties make neoprene rubber well suited to a variety of demanding sealing applications.
