Teflon PTFE

Polytetrafluoroethylene (Polytetrafluoroethylene, the English abbreviation for the PTFE, (commonly known as "plastic king"), trade name Teflon ®, the Chinese translation of the trademark is different: mainland China translated as Teflon ®, Hong Kong translated as Teflon ® , The Taiwanese translated as Teflon ®, textbooks are translated as Tefan), the material of the product generally referred to as "non-stick coating" / "easy to clean wok material"; is a use of fluorine-substituted polyethylene All hydrogen atoms are synthesized by polymer materials. This material has acid and alkali resistance, anti-organic solvent characteristics, almost insoluble in all solvents. At the same time, polytetrafluoroethylene has the characteristics of high temperature, its friction coefficient is very low, so it can be used for lubrication, but also become a non-stick pot and the inner layer of the ideal coating. Applications of Teflon PTFE Sheet : • Seal, seats, packing, chevrons • Piston rings, glide rings, lantern rings, back up rings, Slide bearings • Electrical and thermal insulators • Wear plates • Bushes, bearings in chemical pumps • O-rings, envelope gaskets • Bellows, lings(chemical), valve seats Key Features of Teflon PTFE Sheet : 1、Chemically inert 2、Insoluble in all known solvents below 300ºC 3、High thermal stability, continuous service temperature range -270º to 260ºC 4、Low coefficient of friction 5、Outstanding electrical and dielectric properties 6、Resistant to stress cracking and weathering 7、Limited use in structural components because of low modulus of elasticity 8、Poor wear resistance 9、Poor mechanical strength 10、Non toxic EU and FDA approval for food contact applications 11、Very high specific gravity 12、Easy to machine
