PTFE is an important variety of engineering plastics and has a wide range of applications. It has excellent high and low temperature performance and chemical stability, excellent electrical insulation, non-adhesion, weather resistance, non-combustibility and good lubricity.
Application
Chemical-resistant, non-adhesive liquid transfer machine joints are not covered with protection
Sensor protection
Metal ball non-adhesive
Protection of medicines at high temperatures

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.
