Chlorinated paraffin is a group of chemicals that consists of chlorinated hydrocarbons. They are widely used as flame retardants and plasticizers in various industries, including the manufacturing of plastics, rubber, paints, and textiles. Chlorinated paraffins are formed by the chlorination of long-chain hydrocarbons and have varying degrees of chlorine content.
Chlorinated paraffin offers several beneficial properties, including excellent thermal stability, flame retardancy, low volatility, and chemical resistance. These properties make them valuable additives in the production of flexible PVC products, such as cables, pipes, and flooring materials. They act as effective flame retardants, improving the fire resistance of these materials.
