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.
