Heat Resistance Wire

FEP insulated wire

The maximum continuous operating temperature is 200℃.

FEP insulated wire has excellent electrical and mechanical properties as well as heat, cold and chemical resistance.Particularly suitable for high-temperature environments such as around furnaces and engines.It is also suitable for extremely low temperature environments and environments exposed to chemicals such as chemical factories.


  • The maximum continuous operating temperature is 200℃.
  • It has excellent electrical properties such as low relative dielectric constant and low dielectric loss.
  • It has excellent heat and cold resistance, oil and chemical resistance, and is nonflammable.


  • Internal wiring of electronic equipment, information equipment, etc.
  • Secondary lead wire for general equipment
  • Wiring around furnaces and engines that get hot
  • Wiring in extremely low temperature environments (below -200℃)
