Only DuPont makes Teflon®. To be sure you'll get the performance benefits available with DuPont fluoropolymers, specify them by name. Teflon® AF, FEP, NXT, PFA, and PTFE, as well as Tefzel® ETFE are all products that are part of the DuPont Fluoropolymers family.
Teflon® PTFE fluoropolymer
DuPont™ Teflon® PTFE (polytetrafluoroethylene) has exceptional resistance to high temperatures, chemical reaction, corrosion, and stress-cracking. The mechanical toughness, electrical, and low-friction properties of Teflon® make it the preferred plastic for a host of applications and different processing techniques. Teflon® PTFE is available from Professional Plastics in Sheets (pressed or skived), Rods, Tubing (Extruded or Molded), Films, and Heat Shrinkable Tubing.
Teflon® 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. Also available in FEP Sheets, Rods, Tubing & Heat Shrinkable Roll Covers from Professional Plastics.
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 is available from Professional Plastics Sheets, Rods, Tubing & Films.
Tefzel® ETFE fluoropolymer
Tefzel® combines superior mechanical toughness with an outstanding chemical inertness that approaches that of Teflon® fluoropolymer resins. Tefzel® 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. DuPont™ Tefzel® is a modified ETFE (ethylene-tetrafluoroethylene) fluoropolymer available in Sheets, Rods, Tubing & Films from Professional Plastics.
Manufacturing components of Teflon® is easier and more efficient than ever before, thanks to the high-strength welding and thermoforming capabilities of Teflon® NXT. Machining time and scrap losses can be cut because components are built up from smaller parts rather than machined from large billets.
DuPont Engineering Polymers and Elastomers include a broad range materials including; Delrin®, Nylon®, Teflon®, Surlyn®, Kalrez®, Vespel®, Kapton®, Nomex®, Viton® and many more. Professional Plastics distributes many of these DuPont products in basic shapes such as Sheets, Plates, Rods, Bars, Tubes, Films, and O-Rings.
