Chlorinated Paraffin’s (CPs) are straight-chain hydrocarbons that have been chlorinated. It is manufactured by chlorination of liquid n-paraffin wax and certain form of chlorine it is 30-70% chlorine. The properties of CPs are inertness, almost insoluble in water, and having low vapour pressure. They are sold in both liquid and sold forms. By increasing the content of chlorine higher viscosity and density is achieved.

The majority of CPs produced are CP 40, C14H24Cl6 and CP 52 C14H24Cl6.

As a plasticiser CPs are generally used as a replacement for DOP and DBP bringing down the cost of manufacturing PVC. The technical benefits are varied harness and softness, tensile strength, elongation break paths and heat resistance. It is widely used for its enhancement of flame-retardant properties. This is of advantage for PVC flooring and cables. The plasticiser is also used in paints, sealants and adhesives where again the advantages are enhancement of flame-retardant but also inertness of the product.
