Extruded PTFE Tubes

Extruded PTFE Tubes

Extruded PTFE Tubes are divided into three categories according to their processing technology: tubes with a diameter of 4mm-9mm are made by dispersing polymerized PTFE resin by paste pressing; tubes with a diameter of 10mm-50mm are selected as suspension PTFE. The resin is made by extrusion; the tube with a diameter of 50mm-300mm is made by molding.

Product Features

Main features of PTFE tube :

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. 

7. Slidability: PTFE coatings have a lower coefficient of friction. The friction coefficient changes when the load slides, but the value is only between 0.05 and 0.15.

8. Moisture resistance: The surface of Teflon coating is not water and oily. It is not easy to get into the solution during production. If there is a small amount of dirt, it can be removed by simple wiping. Short downtime, saving time and increasing productivity.

9. Wear resistance: Excellent wear resistance under high load. It has the dual advantages of wear resistance and non-sticking under a certain load.
