Product Description
Chlorinated Paraffin is a non-flammable, non-corrosive, and thermally stable mixture of polychlorinated alkanes. It appears as a clear pale-yellow liquid (for shorter chains) to yellowish solid wax (longer chains) with low volatility. Soluble in tetrahydrofuran, chlorinated solvents, and oils, it exhibits neutral pH (6.0–7.5) and excellent chemical resistance. Its chlorine content enhances flame retardancy and lubricity while maintaining compatibility with polymers and industrial fluids.
