Basic Properties of PTFE

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.
