Neoprene Rubber

Neoprene Rubber, CR, also known as polychloroprene is another synthetic rubber known for its resistance to oils, oxidation, ozone and flame. It is generally resistant to moderate chemicals and acids, ozone, oils, fats, greases and solvents. It is generally attacked by strong oxidizing acids, esters, keytones, chlorinated aromatic and nitro hydrocarbons. General applications include hose, belting, wire and cable, footwear, tires, bearing pads and impellers.
