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 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 & 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.
