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℃. Certain high fluorinated oils swell & dissolve PTFE at temperature close to crystalline melting point.
-
Wide operating temperature range -250℃ to +260℃, 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.
