Neoprene rubber (otherwise known as polychloroprene or chloroprene rubber) exhibits good chemical inertia. It is commonly used in electrical installations and weather sealing applications. Neoprene is particularly suitable for use with water; be that salt or fresh water – although for potable (drinking) water it is better to use EPDM rubber.
It doesn’t support combustion, but self extinguishes. Neoprene also has good resistance to sunlight, ozone and oils. It is ideally used in temperatures ranging from -20ºC to +110ºC.
