Chloroprene Rubber

Chloroprene is a liquid resembling isoprene in chemical structure, except that it has a chlorine atom where isoprene has a methyl group. Because of this, chloroprene rubber or polychloroprene offers greater resistance to oils and solvents than natural rubber or SBR, and to the destructive effects of sunlight, aging and oxidation. Its heat resistance is also good – even above 100oC in suitable compounds. Its resilience is lower than that of natural rubber and decreases fairly rapidly at lower temperature. Its strength and abrasion resistance are good. It has very good properties and is effectively flame proof. It is used in a wide range of applications in the non-tyre sector of the industry. Chloroprene rubber is used for the covering layer in most types of oil hose, and frequently for the lining through which the oil flows. It is used in mechanical rubbers when heat resistance is required and the changes of oil contact is likely. It is used for seals, strip and other components in the automotive industry, window gaskets, and roofing sheet in buildings, bridge and building bearing pads, chemical plant lining and electric cable covering. Other applications include the water proofing of textiles and tarpaulins, life rafts and inflatable dinghies, and the manufacture of paints.
