Moulded PTFE Tubes

Moulded PTFE Tubes

Moulded 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 Moulded PTFE Tubes :

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.

Application

1. Anti-corrosion performance application

PTFE materials have become the main corrosion-resistant materials in the petroleum, chemical, textile and other industries due to their excellent corrosion resistance. Specific applications include: conveying pipes for corrosive gases, exhaust pipes, steam pipes, high-medium and low-pressure pipes in aircraft hydraulic systems and cold-press systems.

2. Low friction performance in load applications

Specific uses include: bearings for chemical equipment, paper machinery, agricultural machinery

3. In electrical and electronic applications

The inherent low loss and small dielectric constant of PTFE materials make it an enameled wire for use in micro motors, thermocouples, control devices, etc.

4. Anti-stick performance application

PTFE material has the smallest surface tension in solid materials, does not adhere to any position, and colleagues also have excellent properties of high and low temperature resistance.
