Teflon™ PFA
Fluoropolymer Film

Properties Bulletin
Description• Melting range: 300 to 310 °C (572 to 590 °F)

Teflon PFA film is a transparent, thermoplastic film that canbe heat sealed, thermoformed, vacuum formed, heat bonded,welded, metallized, laminated (combined with dozens of othermaterials), and used as an excellent hot-melt adhesive. A
cementable type with an invisible surface treatment is available
for bonding to one or both sides with adhesives. This wide
variety of fabrication possibilities combines with the following
important properties to offer a unique balance of capabilities
not available in any other plastic film.

• Heat sealable™

Mechanical Toughness• Superior anti-stick and low frictional properties• High resistance to impact and tearing• Useful physical properties at cryogenic temperatures
Long Time Weatherability*• Inert to outdoor exposure• High transmittance of ultraviolet and all, but far, infrared

Chemical Compatibility

Teflon™ PFA film is chemically inert and solvent-resistant tovirtually all chemicals, except molten alkali metals, gaseous
fluorine, and certain complex halogenated compounds, suchas chlorine trifluoride at elevated temperatures and pressures.
It also has low permeability to liquids, gases, moisture, andorganic vapors.

Reliability• Teflon™ PFA film contains no plasticizers or other foreignmaterials.
• Conventional equipment and techniques can be used forprocessing; basic composition and properties will not beinfluenced.
• Rigid quality control by Chemours ensures uniform gauge,
void-free film.

Electrical Reliability• Superior reliability and retention of properties over large
areas of film

Shelf Life• High dielectric strength, over 260 kV/mm for 0.025-mm film
(6500 V/mil for 1-mil film)

The shelf life of Teflon™ PFA Fluoropolymer Film is:• No electric tracking, non-wettable, and non-charring• Unlimited in terms of the mechanical, chemical, thermal andelectrical properties• Very low power factor and dielectric constant, only slightchange over wide ranges of temperature and frequency• 12 months from the date of treatment for the effectiveness ofthe surface treatment (types CLP and CLP20)

Wide Thermal Range• Continuous service temperature: –240 to 260 °C(–400 to 500 °F)*Type C film is not recommended for outdoor use.
