PTFE

PTFE is polymer which is extensively used in chemical, mechanical, electronic & electrical industries due to its unique characteristics.

  • Chemical interness to all known chemicals however attacked by molten alkali metals, chlorine, trifluorides, fluorine & related fluorine complexes at elevated temperature & pressure.
  • Resistance to solvents, insoluble in all solvents upto 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 & nonmetals.
  • Nontoxic & anti-stick properties.
  • Negligible water absorption.
  • Nonflammable.
  • Resistance to radiations, electrical properties remain practically unchanged during & after irradiation, both in air & vacuum.
  • Excellent weathering resistance.
