Abstract
A thermoplastic material, and in particular a jacket for an electrical cable, and more particularly a jacket for a THHN electrical cable, includes a polyamide base material, a silicon elastomer and an ethylene polymer modified with an unsaturated aliphatic diacid anhydride. The silicon elastomer does not migrate through the jacket. The jacket has a lower coefficient of friction than a cable with a jacket that does not have a silicon elastomer incorporated therein, and the resulting cable requires less force to install than a cable without a lubricant incorporated therein. The cable also has improved flame resistance and elongation-to-break properties. Methods for making these thermoplastic materials are also described.
