PTFE – POLY TETRA FLUORO ETHYLENE

GENERAL PROPERTIES
PTFE is a polymer which is extensively used in Chemical, Mechanic, Electronic & Electrical Industries due to its own unique characteristics.

*Chemical Inertness to all known chemicals however attacked by molten alkali metals, chlorine, trifluorides, fluorine & related fluorine complexes at elevated temperatures & pressure.

*Resistance to Solvents, insoluable 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 + 260 C, at atmospheric pressure.

*Lowest coefficient of friction among all known metals & non-metals.

*Nontoxic & antistick properties.

*Negligible water absorption.

*Nonflammable

*Resistance to radiation : electrical properties remain practically unchanged during & after irradiation, both in air & vaccum.

*Excellent weather resistance.

*Outstanding electrical \ insulating properties over wide frequency range.

Filled PTFE (Teflon®) gaskets are made from PTFE which integrates additives and fillers in order to improve the performance of the gasket. This improves the gaskets ability to wear and enhances its unique combination of chemical, physical and electrical properties.While PTFE gasket material is exceptional in it’s range of temperature (to 500 F) and PH range (0-14) it has limitations on the thickness available. Most PTFE sheet is skived off of a roll. Some material is molded but this is generally limited to 24″ x 24″ or 12″ x 12″ sections.
