Teflon Tube (PTFE)

                        TEFLON® PTFE (Polytetrafluoroethylene)

PTFE (Teflon Tube) is the mostly consumed category of florin plastics, Which has the lowest coefficient of friction

in all the engineering plastics, Whose long-term working temperature can reach 200 to 260. It has the excellent chemical corrosion-resistance, which is able to endure All kind of chemistry material. And it has rather good electricity-resistance, which is not affected by the temperature and is called Kind of plastics.

PTFE plastic has excellent corrosion-resistance, aging-resistance, high(low) temperature resistance, good lubrication and insulation, non-adhesiveness, toxicological harmless. It is widely used in industries like aviation, chemical industry, electric and electronics, bridge, mechanical manufacturing, textile, paper making, ceramics etc.

Application:

1  Aviation industries: Medium lead equipments in hydraulic pressure system and the highmiddlelow pressure piping in the cold pressure system of airplane, capacitor and so on.

.

2  Construction and building industries: bridge, tunnel, steel structure house-support, large-scale chemical pipeline, supporting block of store trough, the supporting pedestal of bridge and the bridge-span circumvolving system and so on.

3  Chemical machine equipment industries: widely applied in the bearing of paper-making

machine and agricultural machine, as the piston ring, machine tool oriented rail and

oriented ring.

4  Electronic and electrical industries: can make insulated wire, capacitor, radio insulated

gasket, insulated cable, and the parts of transformer, oxygen sensor, microphone,

loudhailer and robot.

5medical treatment field: PTFE is the totally inert material, which has very strong biology

 applicability, has not any circadian side-effect to the body. So it can be applied in surgical

operation suture for the body parenchyma regeneration.
