Resin
Teflon® FEP is a fluorinated ethylene propylene resin that meets the ASTM Standard Specification for FEP—Fluorocarbon Molding and Extrusion Materials under ASTM Designation D2116-95a. It is available as pellets or as stabilized aqueous dispersions. Applications for this family of resins include coating, melt extrusion, and impregnating. Products made from Teflon® FEP are known for their excellent chemical resistance, superior electrical properties, and high service temperatures of up to 200°C (392°F). In addition, Teflon® FEP provides outstanding low-temperature toughness and unique flame resistance.
Teflon® FEP fluoroplastic resins are processed by conventional melt-extrusion techniques and by injection, compression, transfer, and blow-molding processes.
The high melt strength and draw-down capability of these resins facilitate the use of large dies and draw-down tooling to increase production rates. Equipment in contact with molten resin should be made of corrosion-resistant metals.
Larger length-over-diameter extruder barrels are used to provide enough residence time at high production rates to melt these high-temperature polymers. Reciprocating screw injection molding machines are recommended.

Film
DuPont™ Teflon® FEP film is a transparent, thermoplastic film that can be heat sealed, thermoformed, vacuum formed, heat bonded, welded, metalized, laminated-combined with dozens of other materials, and can also be used as an excellent hot-melt adhesive.
This wide variety of fabrication possibilities combines with important properties to offer a unique balance of capabilities not available in any other plastic film.
