PFA film
PFA Film (perfluoroalkoxy) is a sister polymer to FEP and has some enhanced properties, it exhibits all the properties of FEP with the addition of:
- Extraordinary mechanical strength greatly in excess of FEP.
- Resists heat up to 250 Deg C in continuous operations.
- More than 10 times the Flex Life of FEP.
- High Purity granules available for semi-conductor environments
Nowadays PFA film and sheets are often used in 3D printing due to these improved properties. We have thicknesses of 50 – 100 – 125 and 150 micron on stock. All in pre-cut sheets or full width:
PFA FILM cut to roll width
PFA Film cut to size
Which thickness do I need?
If you are not sure which thickness PFA film is most suitable for your application. Perhaps our PFA sample package will be of interest.
Properties of PFA film
Low coefficient of friction compared to FEP
Elevated temperature resistance (260 °C)
Stiffer mechanical properties
Higher flex life
Transparent
Not flammable
Applications of PFA film
PFA film
PFA film, short for perfluoroalkoxy, is a melt processable fluoroplastic. PFA is more commonly known as Teflon ® but Teflon® is a brand name of DuPont where PFA is the name of the material.
PFA is more expensive then FEP and PTFE and is a combination of the best properties of these 2 materials.
- Exhibits all the properties of FEP with the addition of:
- Extraordinary mechanical strength greatly in excess of FEP.
- Resists heat up to 250 Deg C in continuous operations.
- More than 10 times the Flex Life of FEP.
- High Purity granules available for semi-conductor environments
Teflon ® PFA film
PFA was invented by DuPont and is sold under the brand name Teflon PFA. Other brand names are Neoflon PFA from Daikin or Hyflon PFA from Solvay Solexis. If you are in need of a specific manufacturer e.g. DuPont and the PFA film needs to be Teflon® graded, please let us know.
PFA film properties
PFA has a unique combination of properties which makes the material suitable for a variety of different and unique applications, these are the main properties:
- Excellent thermal stability:
An elivated temperature resistance up to 250 C
- Chemical Inertness:
Resists almost all chemicals, such as strong acid, strong alkali, salt, and organic solvent.
- Anti-stick property:
The lowest surface energy of all plastic films; displays excellent mold release and anti-stick properties.
- Electrical reliability:
High electrical insulation characterized by low-dialectic constant and dissipation factor and by high dialectic strength over a wide range of temperature and frequency.
- Resistance to weathering:
Inert to outdoor exposure; with unchanged mechanical and physical properties after 10 years.
- Non-flammability:
Will not burn in air or gas having an oxygen concentration of less than 95%.
- High transparency:
Transparent, with excellent transmission of ultraviolet rays and visible rays
Taking advantage of the elevated temperature resistance, stiffer mechanical properties and low coefficient of friction compared to FEP, these are reasons PFA is used in the 3D printer industry as a release film.
Manipulating PFA film
www.FEP-film.com is part of the Holscot group. Holscot is established in 1970 to investigate the potential of melt processable fluoroplastics like PFA. We developed the skills needed to manipulate and shape these materials, this includes welding, thermoforming, etching and bonding techniques.
If you are in need of some more complex PFA shapes by manipulating the film, please contact us to see what we can do for you.

Other Film or sheets
Besides the 4 thicknesses of PFA film that we hold on stock and sell by the meter or in small pieces you can always contact us for other thickness. Further we also sell the more economically priced FEP film in 7 thicknesses from stock. Or ETFE film in 100 and 200 micron thick.
ETFE film in 100 and 200 micron and PFA film in a variety of thicknesses. Please contact us for more information. If you need FEP self-adhesive film, we can offer this as well.
