Chlorinated paraffins

Chlorinated paraffins (CAS 63449-39-8), also marketed as chlorinated waxes and commonly abbreviated as CP, are produced by chlorinating straight-chain paraffin fractions to varying chlorine content levels.

Where is Chlorinated paraffins used?

• PVC compounding: extend primary plasticizers such as phthalates while contributing flame retardancy to cables, flooring, and flexible profiles
• Metalworking fluids: extreme-pressure additives in cutting, stamping, and drawing operations
• Rubber compounds for industrial belting and seals: improve flame resistance and processing characteristics
• Leather finishing: durable flame-retardant treatment
• They function simultaneously as flame retardants, secondary plasticizers, and extreme-pressure lubricant additives.

Good to know: Buyers should confirm chain-length classification given differing regional regulatory status across SCCP, MCCP, and LCCP categories.

Commercial specifications

• Chlorine content typically ranges from approximately 40% to 70% by weight.
• Short-chain, medium-chain, and long-chain grades are the primary commercial classifications.
• Specific grades are selected based on application viscosity and the specific regulatory requirements of the target market.
