CHLORINATED PARAFFIN

Chlorinated Paraffin is a versatile secondary plasticizer and flame retardant obtained by chlorination of straight-chain paraffins, with widespread industrial use. It is particularly preferred in the PVC (Polyvinyl Chloride) industry to reduce the cost of primary plasticizers and to increase the fire resistance of the final product. It is a chemically stable, low-volatility, and water-immiscible viscous liquid.

Industrial Advantages and Functions

Chlorinated paraffin creates an excellent flame retardant effect in the systems where it is used. It suppresses the combustion process by releasing chlorine under heat. Simultaneously, with its secondary plasticizer property, it provides flexibility in PVC formulations and offers cost efficiency. It helps maintain flexibility even at low temperatures and increases chemical resistance. In metalworking fluids, it minimizes friction as an Extreme Pressure additive.

Usage Areas

The most common usage area for chlorinated paraffin is in soft PVC applications such as cable, hose, and artificial leather production. It is also widely used in rubber components, flame retardant paints, mastic and sealing products (sealants), and textile coatings. In the metallurgy sector, it is a critical performance-enhancing component in cutting and drawing oils.

Frequently Asked Questions

What is the function of chlorinated paraffin in PVC formulations?

It acts as both a cost-reducing secondary plasticizer and imparts flame retardant properties to the product, thereby enhancing safety standards.

What are the storage conditions for chlorinated paraffin?

It should be stored in its original packaging in cool, dry, and well-ventilated environments, protected from moisture exposure. Prolonged contact with iron and steel can cause corrosion, so storage in suitably coated tanks is recommended.
