Manufacturing an insulated conductor and the article produced thereby

Abstract From the Canadian patent

Abstract of the Disclosure, A conductive element is advanced along a path and is preheated to within a controlled temperature range. A reaction mixture is extruded about the conductor the, preheat of which reacts the reaction mixture and causes a release of a reaction product to etch the surface of the conductor. This results in an insulated conductor having surprisingly desired adhesion values of the insulation to the conductive element without degrading the overall physical and mechanical properties of the insulation. In one usage, the reaction mixture is plasticized polyvinyl chloride with hydrochloric acid being released to perform the etching.
