Graphite filled ptfe expanded joint belts factory supplier

    product description About PTFE PTFE is made by polymerization of tetrafluoroethylene polymer,which has excellent chemical stability, corrosion-resistance, sealing, self-lubrication,nonstick, electrical insulation and good anti-aging endurance, excellent high and low temperature capability . The mechanical properties of PTFE will be improved if add some fillers, while maintaining other PTFE excellent performance.There are several varieties of fillers such as glass fiber, metal, metal oxides, graphite, molybdenum disulfide, carbon slender, polyimide, EKONOL and so on. PTFE is excellent for low friction bearings, bushes, rollers and pulleys. PTFE is also almost exclusively used in cryogenic components due to its ultra low operating temperatures. Unfilled P.T.F.E canbe characterised by the following properties: Chemically inert Insoluble in all known solvents below 300ºC High thermal stability, continuous service temperature range -270º to 260ºC Low coefficient of friction Outstanding electrical and dielectric properties Resistant to stress cracking and weathering Limited use in structural components because of low modulus of elasticity Poor wear resistance , Poor mechanical strength Non toxic EU and FDA approval for food contact applications   Description
It is made of pure PTFE, can be widely used in the transport and sealing of industrial fluids. It is the most cost-effective alternative to sheet gasketing for large equipment flanges. Because it is a form-in-place Gasket, so it nearly can be used in any sealing surface. Especially for the irregularities and damaged flange surface, expanded PTFE Tape is the best choice.
Best properties
1.Easy to install
2.Low stress-to-seal
3.Can conform to any surface, including rough, pitted, scratched and damaged  surfaces.
4.Resistant to creep and cold flow
5.100% expanded PTFE, has the same chemical inertness of pure virgin PTFE.
6.Unlimited Shelf Life
7.Over compression is no problem
Technical index

 Application PTFE expaned tape is especially suited for sealing flange connections, pipe systems, hydraulic and pneumatic systems, etc. In addition, it’s also ideal for seals in glass, enamel and plastic flanges, vessels and special shaped sealing surface.
PTFE expaned tape saves money and time. Since there is no scrap or waste, it costs less than other gasket materials. By using only a few sizes, large inventories of sheet gasketing and costly precut gaskets can be eliminated. Installation time is kept to a minimum since there are no templates, precutting or special fitting requirements.  Products display     Company information:   Shaanxi Tiangogn PTFE& Plastic Material Co.,Ltd in Xi'an China is a professional manufacturer of all kinds PTFE products.We can provide all kinds of high quality Ptfe moulded & extruded rod,sheet,skived sheet,film, thread seal tape,expanded seal tape, packing, sealing, valve seats and so on to fulfill the needs of our worldwide clients.In the domestic we have copperated with many military college to improve our products line of filled PTFE products.Now our products have widely application in Chemical,mechanical ,electronical, petrol and some other applications.   Our products can be used at the following fields:   Ps : 1.We support that any size as customer inquiry with out mould fee .          2.Free sample can get to your office directly just need freight collected .    Packaging & Shipping:   Packing details : Packed by film then by wooden case or carton case.   Delivery Detail: Within 7--15 days after get deposit or depends on quantity.      FAQ:   1.How can I get a sample?   Normally small sample (sizes less than 150*150mm) can be sent free of charge .Freight collect or Negotiable .   2. MOQ can be 50KGS or 100kgs ?   Yes, You can place your small order . Pls kindly tell us your ordering weight or pieces, we would quote for you immediately . Because the unit price cost and freight cost of small order would be higher than MOQ'S . Pls also consider our MOQ ,the cost can be reduced .   3. Can we order a large quantities with a discount price ?   Yes, you will be quoted a better price if qty is large . The larger the volume is, the more discount you can enjoy.
