PFA Films
CHEMFILM PFA Film provides the highest continuous use temperature 260°C (500°F) of any melt-processable fluoropolymer film. PFA film offers many of the performance properties of PTFE in a clear, transparent form and can be heat sealed, thermoformed, welded, metalized, or laminated to a wide variety of materials.
We offer two different options for PFA film:
- CHEMFILM PFA-PG general purpose film
- CHEMFILM PFA-WF welding film

PFA-PG General Purpose Film
PFA-PG, general purpose film, offers a combination of excellent dielectric properties across a wide temperature and frequency range, the highest level of chemical and stress crack resistance, excellent clarity, and weatherability. The chemical resistance of PFA provides excellent tank-lining performance.
BENEFITS:
- Outstanding flex life, stress crack resistance and anti-stick release properties
- Excellent chemical resistivity and weatherability in extreme environments
- Superior dielectric strenth, excellent electrical insulation properties
- Suitable for cryogenic and high temperature applications with a range from -254°C to 260°C
- Available with C-treatment to provide a cementable surface on one or both sides of the film

PFA-WF Welding Film
PFA-WF, mechanical grade welding film, is an ideal economical solution for applications that don’t require high aesthetic standards, such as hot melt adhesive (welding tape) application. PFA WF grade possesses all physical, mechanical, and thermal properties of PFA film while offering up to 25% savings.
BENEFITS:
- Outstanding flex life, stress crack resistance and anti-stick release properties
- Excellent chemical resistivity and weatherability in extreme environments
- Superior dielectric strenth, excellent electrical insulation properties
- Suitable for cryogenic and high temperature applications with a range from -254°C to 260°C
- Available with C-treatment to provide a cementable surface on one or both sides of the film
