[0002] Chlorinated paraffin is an organic substance, a chlorinated derivative of paraffin hydrocarbons, with the advantages of low volatility, flame retardancy, good electrical insulation, and low price. It can be used as a flame retardant and polyvinyl chloride auxiliary plasticizer, and is widely used in the production of cable materials, floor materials, hoses, artificial leather, rubber and other products.
