Abstract

A composition and method for reducing the coefficient of friction and required pulling force of a wire or cable are provided. A composition of aqueous emulsion is provided that is environmentally friendly, halogen free and solvent free. The composition is compatible with various types of insulating materials and may be applied after the wire or cable is cooled and also by spraying or submerging the wire or cable in a bath. The composition contains lubricating agents that provide lower coefficient of friction for wire or cable installation and continuous wire or cable surface lubrication thereafter.

a lubricating composition applied to the insulating material subsequent to the cooling of the insulating material and prior to winding of the electrical cable on a reel, the lubricating composition comprising;

distilled (DI) water;

polyethylene glycol (PEG);

polydimethylsiloxane (PDMS) emulsion;

silicone-based antifoaming agent; and

paraffin wax emulsion.
