PTFE Characteristics & Benefits

Description: PTFE is polytetrafluoroethylene and is available in many grades for a wide range of applications. Products are fabricated from PTFE resin using ram extrusion, molding (for granular resin), and paste extrusion and calendaring techniques (for fine-powder resin), dispersion coating (dispersion based resin).

  1. Fluorotherm manufactures PTFE paste extruded tubing with the following features:
  2. PTFE tube does not contain processing aids that intended as part of the final product.
  3. External filling for PTFE tube may consist of materials such as carbon, boron-nitride, bronze, glass etc., to provide specific performance features such as thermal or electrical conductivity, improved abrasion or cut through resistance.
  4. Extremely high lubricity, thus low coefficient of friction compared to other materials.
  5. PTFE tube is non-stick and non-wetting (hydrophobic), low surface tension with water.
  6. PTFE tube excellent dielectric and electrical insulation characteristics.
  7. PTFE tube exceptional chemical inertness.
  8. PTFE tube can use upper temperature use limit for PTFE is 500°F (260°C) under non-stress conditions.
  9. PTFE tube suitable for cryogenic conditions. PTFE resins remain strong and tough down to -320°F (-96°C); the boiling point of liquid nitrogen. Several sources have reported some ductility at -450°F (-268°C). For details on cryogenic behavior and properties, please contact Fluorotherm.
  10. PTFE tube low extractables.
  11. PTFE tube is easily purged and cleaned.
  12. PTFE tube made of PTFE fine powder resin is clear at wall thicknesses of less than 0.020” (0.5 mm) and translucent with reasonably good visibility at higher wall thicknesses.
  13. The chemical inertness and UV resistant characteristics of PTFE leads to excellent weathering and aging properties even under aggressive conditions.
  14. PTFE is adversely affected by ionizing (electron beam) irradiation; in fact irradiation is used to produce some useful products.
