Features and Application of Chlorinated Paraffin 52

Chlorinated paraffin is golden yellow or amber viscous liquid, non-flammable, non-explosive, and extremely low volatility. Soluble in most organic solvents, insoluble in water and ethanol. When heated to above 120℃, it will slowly decompose by itself and can release hydrogen chloride gas. And the oxides of iron, zinc, and other metals will promote its decomposition. Chlorinated paraffin is an auxiliary plasticizer for polyvinyl chloride. Low volatility, non-flammable, odorless. This product replaces a part of the main plasticizer, which can reduce the cost of the product and reduce combustibility.



The plasticizing performance of chlorinated paraffin 52 is lower than the main plasticizer, but it can increase the electrical insulation and flame resistance and can improve the tensile strength. The disadvantages of chlorinated paraffin 52 are that the aging resistance and low-temperature resistance are poor, the secondary recycling effect is also poor, and the viscosity is high. However, under the condition that the main plasticizer is scarce and expensive, chlorinated paraffin 52 still occupies part of the market.

Chlorinated paraffin 52 can be mixed with ester-related substances, it can form a plasticizer after mixing. In addition, it also has characteristics as flame retardant and lubrication. If necessary, it can also play a role in antisepsis.

The production capacity of chlorinated paraffin 52 is very strong. In the application process, mainly use thermal chlorination method and catalytic chlorination method. In special cases, photochlorination methods are also used.


1.Chlorinated paraffin 52 is insoluble in water, so it can be used as a filler in coatings to reduce cost, increase cost-effective and waterproof and fireproof properties.

2.Used in PVC products as plasticizer or auxiliary plasticizer, its compatibility and heat resistance are better than chlorinated paraffin-42.

3.It can also be used as an additive in rubber, paint, and cutting fluid to play the role of fire resistance, flame resistance, and improve cutting accuracy, etc.

4.It can also be used as an anticoagulant and an anti-extrusion agent for lubricating oils.
