Calfornia Fine Wire offers polytetraflouroethylene (PTFE) coatings that can be enameled to almost all of its 1,000 metals and alloys. A proprietary process applies liquified PTFE to fine wires in continuous lengths of up to 10,000 feet. The wire is then run through a furnace to set the coating. The coating is said to be a good insulator, with a dielectric strength of 5,000 volts.
