There are three types of PTFE tube
1.Paste Extruded Tube
The tube is made by paste extruded with disperse rsin.
2.Plug Extruded Tube
The tube is made by plug extruded with suspension rsin.
3.Molded Tube
The tube is made by molded method....
Virgin PTFE and filled with other materials. Specified materials are also ok

Product Features
Main features of pure PTFE sheet :
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.
Even if PTFE products have excellent properties, like high/low temperature resistance, chemcial resistance, weathering resistance, dielectric superiority and high lubricity, sometimes we still need to improve its hardness, wear resistance, creep resistance and dimensional stability.
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.
The forming process of PTFE pipe has push method, extrusion method, hydraulic method, welding method and winding method. A PTFE resin is generally used, having a particle size of 500 μm and an apparent density of 0.45 g/ml to 0.55 g/ml.
The mechanical strength of PTFE pipe is the same as that of steel pipe, with the advantages of steel pipe and plastic pipe.
Excellent anti-corrosion performance, effectively resisting the corrosion of pipelines caused by corrosive media such as acid and alkali
