DuPont™ Teflon® PFA

DuPont™ Teflon® PFA fluoropolymer resins are typically used for electronic and specialty cabling applications.  Our family of Teflon® PFA resins combine the processing ease of conventional thermoplastic resins with excellent properties to meet many of your high-demand wire and cabling needs.

DuPont™ Teflon® PFA fluoropolymer resins offer:

  • High chemical resistance
  • Superior electrical properties
  • High continuous service temperatures up to 260°C (500°F)
  • Superior creep resistance at high temperatures
  • Excellent low-temperature toughness
  • Exceptional flame resistance

Teflon® PFA fluoropolymer resins can be processed by conventional melt-extrusion techniques as well as 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 can contribute to improved processing rates.

 

How DuPont™ Teflon® PFA Products Can Fit
Your Cabling Application Needs

DuPont offers a variety of fluoropolymer resins to meet a wide range of demands of the wire and cable industry.  Each of our Teflon® PFA fluoropolymer resins is supported by DuPont long history of scientific expertise and leadership in the fluoropolymer field.  Our experienced sales staff can help you select the correct resins to maximize your business potential.

Family of DuPont™ Teflon® PFA Resins
For Wire and Cable Applications

DuPont™ Teflon® PFA 340

Teflon® PFA 340 is a general-purpose resin of intermediate molecular weight, mainly used for primary wire insulation in applications where good heat resistance is needed. Teflon® PFA 340 is suitable for extruded tubing, hose, electrical insulators, sleeving, industrial film, and injection-molded articles requiring superior electrical, chemical, and thermal properties. Teflon® PFA 340 is available in clear, 2.5 mm (0.1 inch) pellets.

DuPont™ Teflon® PFA 345

Teflon® PFA 345 is an extrusion and injection molding resin with good heat resistance and higher stress-crack resistance than Teflon® PFA 340. Teflon® PFA 345, with a melt-flow-rate of ~7, is an excellent choice for wire and cable insulation, injection-molded parts, and for linings in bellows, valves, fittings, pipes, and other fluid-handling components that require chemical resistance. Teflon® PFA 345 is available in clear, 2.5 mm (0.1 inch) pellets.

DuPont™ Teflon® PFA 3000

Teflon® PFA 3000 is a general-purpose resin that combines the processing ease of conventional thermoplastics with the ability to fulfill demanding end uses. Teflon® PFA 3000 is used when traditional extrusion and molding processes are required for producing products with the superior properties of a fluoropolymer resin.

Teflon® PFA 3000 combines high flow rate, high melt strength, stability at high processing temperatures, and resistance to creep at high service temperatures to provide a superior balance of end-use properties. Teflon® PFA 3000 also provides chemical inertness to nearly all industrial chemicals and solvents, exceptionally low dielectric constant, low dissipation factors, and resistance to ignition.

Teflon® PFA 3000 is available in clear, 2.5-mm (0.1-in.) pellets.

DuPont™ Teflon® PFA C-980

Teflon® PFA C-980 (perfluoroalkoxy) fluoropolymer resin combines the chemical and high-temperature resistance of other Teflon® PFA resins with antistatic levels of electrical conductivity. Teflon® PFA C-980 fluoropolymer resin can be processed by conventional thermoplastic techniques such as melt extrusion, compression, transfer, and blow molding processes.

Properly processed products using Teflon® PFA C-980 provide thermal stability at high processing temperatures along with chemical inertness to nearly all industrial chemicals and solvents. Molded products using Teflon® PFA C-980 have moderate stiffness, excellent toughness, low coefficient of friction, non-stick characteristics, resistance to creep at high service temperatures, and excellent weather resistance.
