Chloroprene rubber (CR) is a polymer formed by emulsion polymerization of chloroprene as monomer. This kind of rubber contains chlorine atoms in its molecule, so compared with other general rubbers: it has excellent antioxidant, ozone resistance, non-flammable, self-extinguishing after fire, oil resistance, solvent resistance, acid and alkali resistance, aging and gas resistance. Good tightness and other advantages; its physical and mechanical properties are also better than natural rubber, so it can be used as general-purpose rubber or special rubber. The main disadvantages are poor cold resistance, large specific gravity, high relative cost, poor electrical insulation, and easy sticking, scorching, and mold sticking during processing. In addition, the raw rubber has poor stability and is not easy to store. Operating temperature range: about -45℃~＋100℃.
Mainly used to manufacture cable sheaths and various protective covers and protective covers that require high ozone resistance and aging resistance; oil and chemical resistance hoses, tapes and chemical linings; flame-resistant rubber products for underground mining, and Various molded products, sealing rings, gaskets, adhesives, etc.
