Properties of Unfilled PolyTetraFluoroEthylene - PTFE

PolyTetraFluoroEthylene - PTFE has unique & versatile properties. Due to unique & versatile properties of PTFE, it finds the applications of many service conditions.

• Chemical inertness to all known chemicals however attacked by molten alkali metals, chlorine, triifluorides, 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.
