Brief analysis of PTFE filled and impregnated products

August 12, 2023

Filled products:

In order to improve the creep properties and wear resistance of polytetrafluoroethylene, polytetrafluoroethylene is filled and modified with graphite, carbon black, molybdenum disulfide, glass fiber, carbon fiber, polyphenylene sulfide and the like as main materials.

Main uses: gaskets, valve seats, seals, bearings, sliders, piston rings, etc.

Impregnated products:

It is a high-temperature resistant product made of high-strength glass fiber yarn woven into various thicknesses of base fabric, then impregnated with PTFE and treated with high-temperature silica gel.

Uses: Textile printing and dyeing, printing and drying guide tape, screen printing, UV drying, food baking machine guide belt, food, medicine, composite plastic bag heat sealing, anti-corrosion pipeline lining, etc.

Features:

Temperature resistance: continuous use from low temperature to high temperature 70-260 degrees Celsius;

Breathability: the air permeability of the conveyor belt, reducing the heat source cost and improving the drying efficiency;

Chemical resistance: not affected by most chemicals and solvents;

Anti-adhesive: almost all adhesives such as resin, paint, chemicals, etc. can be easily removed;

Bending fatigue resistance: It has high tensile strength and bending fatigue resistance and can be used for smaller wheel diameters.
