Highly cost-effective materials, Fluon® PTFE (Polytetrafluoroethylene) Resins are the most widely used fluoropolymers found in many areas of modern life. Resin properties keep insulation thickness to a minimum while tolerating a wider range of temperatures (-180 °C to 260 °C) than other insulators. Inert to almost all chemicals, PTFE resins also offer good resistance to most solvents. They are suitable for outdoor use with no detriment to properties from extended exposure to the elements.
Fluon® PTFE Resin Grades
To accommodate an ever-growing range of end-use products, PTFE resins are available in different grades
- Coagulated dispersions (CD): White, free-flowing powders made by coagulating dispersions of PTFE. Developed for paste extrusion into tapes, tubes, pipe liners and coated wires.
- Aqueous dispersions (AD): Small, negatively charged PTFE particles ranging from 0.25-0.28µm in mean diameter, depending on the grade, that impregnate substrates like fiberglass cloth and metals to impart PTFE properties. Dispersions may contain additional surfactants for stability and wetting properties.
- Granular powders: Fine powders that are molded by first pressing and heating, then shaped by being cut or whittled into sheets, rods or billets. Available in a range of particle sizes and properties. Used for applications requiring superior mechanical or electrical properties.
- They have been developed for paste extrusion into tapes, tubes, pipe liners, and coated wires
- Coagulated dispersions: Suitable for extrusion of thin flexible sections, such as wire insulation, tubing and unsintered tape. They comply with the specifications of ASTM D4895 Type 1.
- Aqueous dispersions: Thermal stability to 500 °F, extreme chemical inertness, resistance to outdoor weathering, low coefficient of friction, and excellent non-stick properties. Dispersions are used for coatings, as a binder, as an additive in resin and as a feedstock for paint.
- Granular powders: Suitable for compression molding of billets, isostatic molding of intricate shapes, automatic molding of stock shapes, compounding with fillers, and ram extrusion of rod and tubing.

Fluon® PTFE Micropowders and FEP Micropowders are lubricants milled to a very fine powder while retaining excellent lubricity properties. These powders can be compounded in rubber and plastics or dispersed in liquids to improve friction and wear properties of the base material. Many grades are used in non-stick surface applications such as extreme pressure additives in oil and grease, and in solvent applications. PTFE and FEP lubricant powders offer great advantages over conventional anti-scuff agents in printing inks, permitting quick solvent release, faster printing speeds, and excellent print gloss.
