PTFE (Polytetrafluoroethylene)
PTFE 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 260ºC. Guangzhou Engineering Plastics Industries (Group) Company has studied and applied this material in many industries for many years. And we know that the PTFE Teflon material has the following main characteristics: 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:
The PTFE Parts that made by Guangzhou Engineering Plastics Industries (Group) Company is used in 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.
.
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.
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.
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.
Color:Natural,White,Black,Coffee and so on.
