Teflon® FEP Resin and Film

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.

Dispersion composed of approximately 54% FEP dispersed in water. Contains a nonionic wetting agent and stabilizer. Fabric and film coating; heat sealable top coatings for PTFE coated fabrics used for belting, circuit boards or electrical insulation, cast film and as hot melt adhesive for bonding molded PTFE or FEP

 




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.
