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.
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.
