Non-lead jacket for non-metallic sheathed electrical cable

1. A jacket for electrical cable comprising:

polyvinyl chloride resin; and

from about 0.1% to about 0.5% by weight of an amide derived from erucic acid, wherein 100% is the weight of the jacket.

2. The jacket of claim 1 wherein the polyvinyl chloride resin is from about 40% to about 50% by weight.

3. The jacket of claim 2 further comprising:

from about 20% to about 30% by weight of a phthalate-based plasticizer;

from about 0.5% to about 50% by weight of a lead-free heat-stabilizing system; and

from about 20% to about 35% by weight of a filler.

4. A jacket for non-metallic (NM) sheathed electrical cable comprising:

from about 40% to about 50% by weight of a polyvinyl chloride resin, wherein 100% is the weight of the jacket; and

from about 0.1% to about 0.5% by weight of an unsaturated primary amide derived from erucic acid.

5. An extrudable chemical formulation for a jacket for electrical cable comprising:

from about 0.1% to about 0.5% by weight of an amide wax, wherein 100% is the weight of the jacket; and

from about 40% to about 50% by weight of a polyvinyl chloride resin.

6. A method of improving the slip characteristics of a jacket for non-metallic (NM) sheathed electrical cable, the method comprising; providing an easy-to-process chemical formulation comprising from about 40% to about 50% by weight of a polyvinyl chloride resin; and adding a wax to the formulation, the wax comprising from about 0.1% to 0.5% by weight of an unsaturated primary amide derived from erucic acid, wherein 100% is the weight of the jacket layer composition with the wax added.
