ABSTRACT:
A non metallic (NM) jacket has from about 40% to about 50% by weight of a polyvinyl chloride resin; from about 20% to about 35% by weight of a filler; from about 0.1% to about 0.5% by weight of an unsaturated primary amide derived from erucic acid; from about 20% to about 30% by weight of a phthalate-based plasticizer; and from about 0.5% to about 5% by weight of a lead-free heat-stabilizing system; wherein 100% is the weight of the jacket. Methods for improving the slip characteristics of a lead-free NM jacket for an electrical conductor are also provided.
