Abstract
Exemplary methods for manufacturing a wire and resultant wires are disclosed herein. The method includes extruding a cross-linkable polymer that is substantially free of curing agent about a conductive core, then adding a curing agent to the extruded wire pre-product, then heat-curing the extruded wire pre-product.
Claims12
A method of manufacturing a wire, comprising:
- extruding a cross-linkable polymer, substantially free of curing agent, about a conductive core to form an extruded wire pre-product;
- adding a curing agent to the extruded wire pre-product, wherein adding the curing agent comprises soaking the extruded wire pre-product in a liquid bath containing curing agent for a time and at a temperature sufficient for curing agent to disperse into at least a portion of the cross-linkable polymer, wherein the time sufficient for soaking is from about 20 seconds to about five minutes, and wherein the curing agent comprises a peroxide;
- and
- heat curing the extruded wire pre-product with the curing agent, wherein a state of cure of at least about 50% is achieved and wherein a cure duration is from about 30 seconds to 30 minutes.
