PTFE film

PTFE film is meant for manufacturing sealing and insulating materials resistant to corrosive mediums and operating in the temperature range from -269 °С to +260 °С in various atmospheric conditions.

PTFE film is matt, smooth, and white to light grey in colour.

There are several types of fluoroplastic-4D film and tape depending on the purpose of their use:

  • KO (Russian code КО) – oriented film for capacitors;

  • EO (Russian code ЭО) – oriented electrically insulating film;

  • EN (Russian code ЭН) – non-oriented electrically insulating film;

  • IO (Russian code ИО) – oriented insulating film;

  • IN (Russian code ИН) – non-oriented insulating film;

  • PN (Russian code ПН) – non-oriented PTFE sealing film.

Ultimate tensile stress of PTFE film is not less than 18 MPa. Film with a thickness ranging from 0.2 mm to 0.5 mm is supplied in rolls with a role core, whereas film with a thickness ranging from 0.5 mm to 3 mm is supplied in rolls without a roll core.
