Abstract
A method of forming a polytetraflouroethylene (PTFE) insulation layer over a metallic conductor of a processed product includes the steps of extruding PTFE over a metallic conductor, and heating the PTFE to a temperature substantially below that of the sintering temperature of PTFE to form a sintered PTFE skin over an unsintered PTFE core.
Claims25
A method of forming a dielectric insulation layer over a metallic conductor of a processed product, comprising the steps of:
- a) extruding a dielectric layer over a metallic conductor;
- and
- b) heating dielectric layer to a temperature of about 500° F. to form a sintered dielectric skin over an unsintered dielectric core.
A method of forming a polytertraflouroethylene (PTFE) insulation layer over a metallic conductor of a processed product, comprising the steps of:
- extruding a PTFE layer with an extruding aid over a metallic conductor;
- vaporizing the extruding aid out of the PTFE;
- and
- heating the PTFE layer to a temperature of about 500° F. to form a sintered PTFE skin over an unsintered PTFE core.
A method of forming a polytetraflouroethylene (PTFE) insulation layer over a metallic conductor of a processed product, comprising the steps of:
- conveying the processed product at a generally constant speed during a fabrication process that includes:
- extruding PTFE with an extruding aid through a die and over a metallic conductor;
- vaporizing the extruding aid out of the PTFE at a temperature of about 450° F.;
- and
- heating the PTFE to a temperature of about 500° F. to form a sintered PTFE skin over an unsintered PTFE core.
