Patent ID: 6972099

Claim:
A semiconductive resin composition for use as a semiconductive layer in contact with a crosslinked wire and cable insulation layer, wherein said insulation layer is crosslinked using a peroxide cure system, said resin composition comprising, 15 to 85 weight percent, based upon the weight of the semiconductive resin composition, of a base polymer comprising at least two components, a first component having a weight average molecular weight of not more than 200,000 and selected from the group consisting of ethylene vinyl acetate copolymers, ethylene alkyl acrylate copolymers wherein the alkyl group is selected from C1 to C6 hydrocarbons, ethylene alkyl methacrylate copolymers wherein the alkyl group is selected from C1 to C6 hydrocarbons and ethylene alkyl acrylate alkyl methacrylate terpolymers wherein the alkyl group is independently selected from C1 to C6 hydrocarbons; a second component selected from the group consisting of polymers having a melting point between 110° C. and 130° C. and nitrile rubbers , wherein said second component is from about 1 to 40 weight percent of the base polymer, and 0.1 to 20 weight percent, based upon the weight of the semiconductive resin composition, of a an adhesion modifying compound different from said base polymer comprising a hydrocarbon wax or ethylene vinyl acetate wax; and 15 to 45 weight percent, based upon the weight of the semiconductive resin composition, of a conductive carbon black in an amount sufficient to give the semiconductive resin composition a resistance below about 550 ohm-meter; wherein said semiconductive resin composition forms a strippable semiconductive layer in contact with said peroxide crosslinked insulation layer.
