Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The best known brand name of PTFE-based …
PTFE is polymer which is extensively used in chemical, mechanical, electronic & electrical industries due to its unique characteristics.
- Chemical interness 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 upto 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 & anti-stick properties.
- Negligible water absorption.
- Nonflammable.
- Resistance to radiations, electrical properties remain practically unchanged during & after irradiation, both in air & vacuum.
- Excellent weathering resistance.
