Wire Coating

Polymer Coating of Wire

Wire and cable insulation and jacketing are produced by extrusion process through a cross-head die which delivers molten polymer onto the insulation jacket. The various insulating materials used in manufacturing of cables are rubber, polyvinyl chloride (PVC), EVA, EPDM, polyethylene and thermoplastic polyurethane resins. Metal ions catalyze the decomposition of peroxide, forming reactive radicals. Metal deactivators form stable complexes with metals, particularly with copper ions. Thus, the stability of polymers in contact with copper, e.g., cable insulation, is largely improved by the use of metal deactivators.
