Chlorinated Paraffin Liquid 52# Industrial Plasticizer

Chlorinated paraffin is a chlorinated hydrocarbon product obtained through the chlorination and refinement of solid wax or liquid paraffin. Chlorinated paraffin-52 is a water-white or yellowish, oily, and highly viscous liquid at room temperature, featuring excellent flame resistance and plasticizing properties. It has a relative density (d₄₅₀) of 1.22-1.27 and a freezing point below -20°C. This product is insoluble in water but dissolves well in benzene, ether, and other organic solvents. Due to its exceptional chemical stability, it is widely used as a cost-effective plasticizer in PVC, rubber, paints, and coatings, as well as a flame retardant in industrial applications.

    Application
    Chlorinated paraffin-52 is a multi-functional industrial additive primarily used as an extender plasticizer in PVC formulations due to its structural similarity to polyvinyl chloride (PVC). It offers:
    ● Low volatility, reducing the risk of plasticizer migration.
    ● Superior flame retardancy, making it ideal for fire-resistant applications.
    ● Excellent electrical insulation, enhancing performance in cable and wiring materials.
    ● Increased gloss and tensile strength, improving the final product's durability.

    Key industries and applications:
    1. PVC-based products: Used as a secondary plasticizer to lower costs in cables, flooring, hoses, plastic doors and windows, and shoe soles.
    2. Rubber industry: Acts as a plasticizer for styrene-butadiene rubber (SBR), nitrile rubber (NBR), neoprene, and polyurethane rubber, improving flexibility and durability.
    3. Paints and coatings: Enhances fire resistance and extends product lifespan.
    4. Metalworking fluids: Used in cutting oils and lubricants as an extreme-pressure additive, reducing friction and wear.
    5. Adhesives and sealants: Improves elasticity and adhesion in industrial and construction applications.

    Storage & Packaging
    ● Packaging: Chlorinated paraffin-52 is supplied in tightly sealed 250KG iron barrels to ensure safety during storage and transportation.
    ● Storage conditions: Store in a cool, dry place, away from direct sunlight and heat sources, to prevent color deepening and degradation.
    ● Handling precautions: Avoid prolonged exposure to air, and transport in compliance with general chemical transportation regulations.
