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.
