PTFE processing Films

FPI series

  • PTFE processing Films
  • Polyimide film


This is the product that is made by coating fluororesin onto a polyimide film. While maintaining dimensional stability equivalent to that of glass cloth coated products, it also ensures surface smoothness of film.

Main applications

• Release sheet
• Insulating sheet

Operating temperature limit

• FPI-S06:+260℃
• FPI-100:+200℃



• It is excellent in heat resistance, chemical resistance, slipperiness and insulation.
• It is superior in dimensional stability and surface smoothness compared with film of fluorine resin alone

*Values shown in this table represent measurements and do not constitute guaranteed values.
*The difference in tensile strength is due to the type of polyimide film.
*The difference in maximum operating temperature varies depending on the type of fluororesin used.
*Please consult us separately for the dimensions other than above.
