China High Performance Custom Made White Teflon Plate, Find details about China Plate, Teflon Plate from High Performance Custom Made White Teflon Plate - Guangzhou Engineering Plastics Industries Co., Ltd.
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. 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. |
