Abstract
Exemplary methods for manufacturing a wire and resultant wires are disclosed herein. The method includes extruding a receptor cross-linkable polymer that is substantially free of curing agent about a conductive core and extruding a donor polymer in association with a curing agent. The method includes disposing the donor polymer about the receptor polymer and conductive core to create a multi-layer wire pre-product. The method also includes heat curing a multi-layer wire pre-product to form a wire.
Claims15
A method of manufacturing a wire, comprising:
- extruding a cross-linkable receptor polymer, substantially free of curing agent, about a conductive core;
- extruding a donor polymer, wherein the donor polymer comprises a curing agent, and wherein the donor polymer is extruded at a temperature of about 125° C. or less;
- disposing the extruded donor polymer about the receptor polymer, thereby forming a multi-layer wire pre-product, wherein the multi-layer wire pre-product is substantially uncured at formation;
- and
- heat curing the multi-layer wire pre-product, wherein the receptor polymer has a state of cure of at least about 50%.
