NEMA HP3 & HP4 (M16878)

For use in internal wiring of electronic equipment and appliances. HP-3 & HP-4 lead wires have a low coefficient of friction which promotes easy handling. The insulation also resists hot soldering irons, is self extinguishing, non-flammable, has excellent chemical resistance and is suitable for immersion in gasoline, gasoline vapor and oil (at 80º C maximum). Weathering, ozone and most corrosive environments do not affect PTFE or FEP insulation.
