Extruded PTFE Bar

The PTFE extruded bar is a bar which is formed by dispersing a resin through a paste extrusion process. Mainly applicable to some long products and non-standard mechanical parts: seals / gaskets, rings, wear plates / seats, insulation parts, corrosion resistance industry, mechanical parts, lining, oil and gas, petrochemical industry , chemical industry, equipment and so on....

Product Features

Main features of PTFE rod:

1. Temperature resistance ---It is able to work stably between -180°C to +260°C.

2. Excellent chemical corrosion resistance ---Applicable medium includes oil, acid solution and almost all chemical materials.

3. Excellent non-sticky property - --With low friction coefficient it easier to remove those resin, dopes, oil and other sticky things.

4. Anti-aging, weathering resistance.

5. Excellent insulation property.

6. Filled material: Filled PTFE products has more outstanding performance by adding filler such as carbon, graphite, bronze, glass fiber, carbon fiber, MOS2, PEEK, PI, POB BaSO4, SiO2, glass bead, polyamide.

Depending on the nature of the PTFE, the filled PTFE plunger extrusion bar is used in many applications. Many connectors are also made of filler PTFE plunger extrusion bars, mainly using its special properties such as corrosion resistance, high temperature resistance and low temperature resistance. Then there are the main parts of heat exchangers, valves and pumps, porous copper impregnated fluoroplastic metal bearings, which can be used under high temperature and high pressure dry friction and vacuum conditions.
