PTFE sheer / board
Introduction:
Teflon sheet (TEFLON / PTFE Polytetrafluoroethylene)
PTFE (Teflon Sheet) 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 endureAll 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
