Sold Out


Film made of fluoroplastic (PTFE).Can be used in a temperature range of -100°C to 260°C, certified for UL94 flame retardancy standard (V-0 or VTM-0, registration number E52859).Many excellent properties such as heat resistance, electrical insulation, sliding property, chemical resistance, and non-adhesiveness.


  • Rich lineup of thicknesses from 0.03 to 1.5 mm.
  • Excellent chemical resistance. Resistant to most acids, alkalis and organic solvents
  • Excellent electrical properties such as high dielectric breakdown voltage, and little dielectric loss.
  • Can be used continuously from -100°C to 260°C (recommended value), and can be used at higher temperatures for short periods of time.
  • The lowest friction coefficient among all solid materials.
  • Adhesive substances do not easily adheres, and can be easily removed from the mold even if coming in contact with it.
  • No hygroscopicity and almost no characteristic deterioration due to ultraviolet rays, etc.
  • Certified for UL94 flame retardancy standard (V-0 or VTM-0, registration number E52859)



  • Improve releasability during molding process. 
  • Mold release and cushioning for thermal compression bonding such as ACF and TCB.
  • Heat-resistant insulation for motor and transformer coils.
