Resin

Teflon™ PFA is a perfluoroalkoxy copolymer resin available in pellet or powder. Teflon™ PFA combines the processing ease of conventional thermoplastic resins with the excellent properties of Teflon™ polytetrafluoroethylene (PTFE).

Products manufactured from Teflon™ 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.

Teflon™ PFA fluoroplastic resins are processed by conventional melt-extrusion techniques and by injection, compression, rotational, transfer, and blow-molding processes. The high melt strength and heat stability of these resins permit the use of relatively large die openings and high-temperature draw-down techniques, which increase processing rates. Reciprocating screw injection molding machines are recommended. Corrosion-resistant metals should be used in contact with the molten resin. Long extruder barrels, relative to diameter, are used to provide residence time for heating the resin to 316° to 427°C (600° to 800°F).

Film

Teflon™ PFA film is a transparent, thermoplastic film that can be heat sealed, thermoformed, vacuum formed, heat bonded, welded, metallized, laminated (combined with dozens of other materials), and used as an excellent hot-melt adhesive.

This wide variety of fabrication possibilities combines with important properties [.pdf] to offer a unique balance of capabilities not available in any other plastic film.
