China Chemical Industry Application CNC Machined Plastic PTFE Bushing, Find details about China PTFE Bushing, Sleeve PTFE from Chemical Industry Application CNC Machined Plastic PTFE Bushing
| TEFLON® PTFE (Polytetrafluoroethylene) PTFE (Teflon) 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. |
