Widely used as a flame retardant and plasticizer in various industrial applications, chlorinated paraffins improve flexibility and durability in PVC and other polymers. They are commonly added to cable coatings, sealants, adhesives, and rubber products to enhance fire resistance and mechanical properties. In metalworking fluids, they act as effective extreme pressure additives, reducing friction and wear during cutting and forming operations. Their compatibility with a range of organic materials makes them valuable in paints, coatings, and textile finishes. Due to environmental and health concerns, mid- and long-chain variants are increasingly favored over short-chain types in many regions.
