Abstract
A cable includes cable one or more conductors and a covering surrounding the one or more conductors. The covering is formed from a composition including polyethylene and a polyolefin elastomer, where the composition is crosslinked. A method of forming the cable is also provided.
Claims6
A cable comprising:
- one or more conductors;
- and
- a covering surrounding the one or more conductors, the covering formed from a composition comprising:
- a single form of polyethylene, the single form of polyethylene consisting of linear low-density polyethylene (“LLDPE”);
- and
- about 10% to about 20%, by weight, of a polyolefin elastomer comprising one of more of an ethylene-octene copolymer and an ethylene-butene copolymer;
- one or more coupling agents, each of the one or more coupling agents being selected from the group consisting of a monomeric vinyl silane, an oligomeric vinyl silane, a polymeric vinyl silane, and an organosilane compound;
- and
- an antioxidant;
- wherein the composition is crosslinked;
- and
- wherein the cable exhibits a % SET value of zero or greater.
