PFA is a perfluoroalkoxy copolymer resin available in pellet or powder. PFA combines the processing ease of conventional thermoplastic resins. Products manufactured from PFA can offer continuous service temperatures up to 260°C (500°F). What's more, Teflon™ PFA provides superior creep resistance at high temperatures, excellent low-temperature toughness, and exceptional flame resistance.
Superior anti-stick properties make it an ideal release film for many applications. Superior anti-stick and low frictional properties, high resistance to impact and tearing, Useful physical properties at cryogenic temperatures, continuous service temperature: – 240 to 260 °C (–400 to 500 °F) are the major highlights of PFA coating.
Thickness can range from 50-60 microns for Non-stick applications (gray) and 200-500 microns for chemical corrosion resistance (Ruby Red).
Teflon™ PFA film is chemically inert and solvent resistant to virtually all chemicals, except molten alkali metals, gaseous fluorine, and certain complex halogenated compounds, such as chlorine trifluoride at elevated temperatures and pressures. It also has low permeability to liquids, gases, moisture and organic vapors.
For chemical corrosion resistance on chemical process equipment’s working at high temperatures PFA is recommended because of its maximum continuous service temperature of 260°C.
Used in aerospace applications.
