Teflon (PTFE)

Category:

PTFE is a polymer which is extensively used in Chemical, Mechanical, Electronic & Electrical industries due to its unique characteristics:

 

  • Chemical inertness to all known chemicals however attacked by molten alkali metals, chlorine, trifluorides, fluorine & related fluorine complexes at elevated temperatures & pressures
  • Resistance to solvents, insoluble in all solvents up to 260°C. Certain high fluorinated oils swell & dissolve PTFE at temperature close to crystalline melting point.
  • Wide operating temperature range -250°C to +260°C, at atmospheric pressure
  • Lowest coefficient of friction among all known metals & non metals
  • Non toxic & anti stick properties/Negligible water absorption/Nonflammable
  • Resistance to radiation : electrical properties remain practically unchanged during & after irradiation, both in air & vaccum
  • Excellent weathering resistance
  • Outstanding electrical/insulating properties over wide frequency range
