Fluoropolymer Resin

Industrial products developed with fluoropolymer coatings, resins, additives, and films have exceptional resistance to high temperatures, chemical reaction, corrosion, and stress cracking. The properties of fluoropolymer make it the preferred solution for a host of industrial applications and different processing techniques.


PTFE (polytetrafluoroethylene) granular molding powders are ideal for molding many different products and stock shapes, such as rods, tubes, and sheets. Products fabricated from PTFE stock shapes are unaffected by nearly all chemicals and feature superior electrical properties. These products, some of which are rated for continuous service at 260°C (500°F), also provide exceptional low-temperature toughness, plus unique adhesion and flame resistance.


FEP is a fluorinated ethylene propylene resin that is available as pellets or as stabilized aqueous dispersions. Applications for this family of resins include coating, melt extrusion, and impregnating. Products made from FEP are known for their excellent chemical resistance, superior electrical properties, and high service temperatures of up to 200°C (392°F). In addition, FEP provides outstanding low-temperature toughness and unique flame resistance.

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.


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

Products manufactured from PFA can offer continuous service temperatures up to 260°C (500°F). What's more, PFA provides superior creep resistance at high temperatures, excellent low-temperature toughness, and exceptional flame resistance. 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).


PVDF coating (polyvinylidene fluoride) is a chemical resistant thick film barrier coating primarily used on chemical processing equipment. This coating is unaffected by most chemicals and solvents and has excellent wear and abrasion resistance. PVDF coatings also have a high dielectric strength, excellent resistance to weathering and the ability to self extinguish.


ETFE (ethylene-tetrafluoroethylene) fluoroplastic is available as pellets or as powder for rotational molding. ETFE resin combines superior mechanical toughness with an outstanding chemical inertness that approaches that of PTFE fluoroplastic resins. ETFE features easy processibility, a specific gravity of 1.7, and high-energy radiation resistance. Most grades are rated for continuous exposure at 150°C (302°F), based on the 20,000-hr criterion.
