Latest Patents

One of John C. Norman's latest patents is a method of coating a metal wire with a temperature and stress-resistant polymer. This innovative process involves preparing an insulated metal wire with a melt-coated, adherent sheath of a polymer. The polymer consists of specific repeat units, where n is 4 or 5, and X ranges from 0.01 to 0.50. The method includes heating the bare wire to a temperature exceeding the glass transition temperature (Tg) of the polymer and then melt-coating the wire. This results in an insulated wire that is stable at high temperatures and resistant to water crazing, cracking, and loss of coating. Another significant patent involves copper wire insulated with a copolyamide sheath, which also demonstrates stability to high temperatures and resistance to similar issues.
