FEP Film

 

FEP film is a transparent fluoroplastic with a unique combination of properties:

  • Resistant to high temperatures (204 ° C)
  • Chemically resistant
  • Ultimate non-stick surface
  • UV stable
  • Not flammable
  • High electrical insulation
  • Very transparent

This unique combination of properties makes FEP film interesting for a variety of  applications. Think of the flexvat for SLA, LCS and DPL 3D printers. UV disinfection systems, FEP as release foil for molds in the composite industry. In the chemical industry, because of the unique chemical resistance, as gasket or as separation foil. These are just a few examples.

You can choose from 7 different standard thicknesses:

If you do not yet know exactly which thickness is most suitable for your application, we also offer a number of FEP sample packages.

Manipulations of  FEP film and specials

 

In addition to the "standard" FEP film, we can also supply glassbacked film. The glassbacked FEP film is resistant to virtually all chemicals on the FEP side and can be attached to almost any surface on the glass side.

We also have years of experience in manipulating FEP film, we even won the prestigious Plunkett Award in the past. We can offer FEP films as:

 

 

By manipulating FEP film we can make various products such as FEP fuel tanks, FEP lens protection caps, FEP bags, containers, belts and much more.
