Abstract
A semiconductive jacket material for jacketing a cable comprising a minor phase material which is a semicrystalline polymer; a conductive filler material dispersed in the minor phase material in an amount sufficient to be equal to or greater than an amount required to generate a continuous conductive network in the minor phase material; and a major phase material which is a polymer which when mixed with the minor phase material will not engage in electrostatic interactions that promote miscibility. The major phase material has the minor phase material dispersed therein in an amount sufficient to be equal to or greater than an amount required to generate a continuous conductive network in the major phase material, forming a semiconductive jacket material of a ternary composite having distinct co-continuous phases.
