Abstract
Disclosed is an improved semi-conductive heating cable having semi-conductive material surrounded by a jacket that is imparted with improved resistance to color change upon exposure to elevated temperatures and is able to minimize changes in the ambient electrical resistivity of the semi-conductive composition arising from exposure of the cable to elevated temperatures by reason of the jacket being made from a radiation crosslinked composition comprising a mixture of at least one elastomer with at least one polyolefin and at least one heat stabilizer wherein the preferred elastomer comprises either or both a terpolymer of ethylene, propylene and at least one diene or an ethylene propylene rubber and the polyolefin is a polypropylene polymer.
