Chlorinated paraffins are obtained by the chlorination of hydrocarbons. These plasticizers consist of 30-70% chlorine which makes them act like flame retardants too. The higher the chlorine content, weaker is the plasticizing effect of chlorinated paraffins for PVC. This category of plasticizers offer high chemical stability and moisture resistance but are thermally unstable, which limits their applications to processing temperatures within 175⁰C. Therefore, for higher processing temperature applications, other stabilizers are added.
