Frequently Asked Questions
What is the full form of CPW in chemistry?
CPW stands for Chlorinated Paraffin Wax. It is also widely called chlorinated paraffin or chloroparaffin. The ~52% chlorine grade we stock is commonly written CPW-52 or CP-52.
What is the CAS number and HSN code of chlorinated paraffin wax?
The CAS number of chlorinated paraffin wax is 63449-39-8. Its HSN code is 38249900.
What is chlorinated paraffin wax used for?
CPW is used mainly as a secondary plasticiser for flexible PVC compounding and cable and wire insulation. It also serves as a flame retardant, in leather finishing, in metalworking fluids, and in paints and rubber.
What is the specification of CPW-52 grade?
Our CPW-52 is a pale yellow viscous liquid with ~52% chlorine content, specific gravity 1.400 ± 0.02 at 27°C, and viscosity of 25–75 Poise (Ford Cup 6mm). Colour is max 50 Hazen with free mineral acidity of max 0.01%. The spec comes from the manufacturer's COA, cross-checked against the published CPW-52 grade specification.
Is chlorinated paraffin wax a flame retardant?
Yes. CPW acts as a flame retardant in flexible PVC, cables and wires, alongside its main role as a secondary plasticiser. That dual function is why cable compounders specify it.
Where can I buy chlorinated paraffin wax in Chennai, and how is it packed?
We stock CPW at our Redhills, Chennai warehouse and dispatch across South India, sourced from Suntek Chlorides Private Limited, an ISO-certified plasticizer manufacturer.
