VERFAHREN ZUM UMMANTELN EINES METALLSTRANGES SOWIE NACH DEM VERFAHREN HERGESTELLTE ELEKTRISCHE LEITUNG

摘要

An electrical conductor 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 causes the reaction mixture to release a reaction product that etches the surface of the conductor. This results in an insulated conductor unexpectedly having desired adhesion values of the insulation to the conductor 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.
