Processing Methods & Reference Formulations

A. PVC products

Incorporate CP during the plasticizing phase, after the primary plasticizer (e.g., DOP) is added, ensuring homogeneous dispersion in the PVC matrix. Choose the grade (e.g., CP-52, CP-60, CP-70) based on chlorine content and viscosity.

Key IngredientsIndicative Dosage (% w/w)
Polyvinyl Chloride (PVC K-67 resin)35%
Chlorinated Paraffin25%
Dioctyl Phthalate15%
Calcium Carbonate18%
Lead-based Stabilizer (or Ca-Zn alternative)2%
Stearic Acid0.5%
Epoxidized Soybean Oil3%

B. Rubber Finishing Paint

Incorporate CP into the resin solution or solvent phase under gentle stirring. Ensure it dissolves fully in aromatic or chlorinated solvents like toluene or xylene for uniform distribution.

Key IngredientsIndicative Dosage (% w/w)
Chlorinated Rubber19–21%
Chlorinated Paraffin (mix of CP-70 and CP-52)8–13%
Titanium Dioxide23–25%
Organic Bentonite1–2%
Talcum Powder3–8%
Precipitated Barium Sulfate5–11%
Dispersing Agent0.3–0.8%
Solvent (e.g., xylene/toluene blend)27–32%

C. Conveyor Belt Compound

Incorporate CP after the elastomer and primary plasticizers have been added. CP is heavier and more polar than standard processing oils. Adjust the aromatic or paraffinic oil content to maintain compound flow, extrusion characteristics, and tack.

FAQs - Chlorinated Paraffin

What are the main applications of Chlorinated Paraffin?
Chlorinated Paraffin is used as a flame retardant and secondary plasticizer in the production of plastics, rubber, and textiles. It is also employed in metalworking fluids, paints, adhesives, and as a lubricant additive.
Are there different types of Chlorinated Paraffin?
Yes, there are various types of Chlorinated Paraffin with different chain lengths and degrees of chlorination. The specific type used depends on the intended application and required properties.
How does Chlorinated Paraffin act as a flame retardant?
Chlorinated Paraffin functions as a flame retardant by releasing chlorine radicals upon exposure to heat. These radicals interfere with the combustion process, reducing the flammability of materials.
Is Chlorinated Paraffin harmful to human health?
The health effects of Chlorinated Paraffin depend on factors such as the degree of chlorination, exposure levels, and specific formulation. Some chlorinated paraffins are classified as persistent organic pollutants (POPs) and may pose environmental concerns.
Is chlorinated paraffin toxic?
Chlorinated paraffin has been associated with potential health risks, particularly due to its chlorine content. Some forms of chlorinated paraffin may contain toxic impurities such as polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), which are carcinogenic and can have adverse effects on human health and the environment.
