PTFE is 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 temperature & pressure.

  • Resistance to solvents, insoluble in all solvents up to 260C. Certain high fluorinated oils swell & dissolve PTFE at temperature close to crystalline melting point.

  • Wide operating temperature range -250C to +260C, at atmospheric pressure.

  • Lowest coefficient of friction among all known metals & nonmetals.

  • Nontoxic & antistick properties.

  • Negligible water absorption.

  • Nonflammable.

  • Resistance to radiations, electrical properties remain practically unchanged during & after irradiation, both in air & vacuum.

  • Excellent weathering resistance.

  • Outstanding electrical/insulating properties over wide frequency range.
