Ptfe liner bushing with good electricity-resistance
TEFLON® PTFE (Polytetrafluoroethylene) 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 260º C. 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 high, middle, low 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.
5, medical 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.
