The Properties and Advantages of PTFE

PTFE is an incredibly versatile material. Polytetrafluoroethylene or PTFE is a particularly versatile ivory-white and opaque plastic fluoropolymer; it is made by the free-radical polymerisation of many tetrafluoroethene molecules, and is suitable for a wide range of applications in industries as diverse as aerospace, the food and drink industry, pharmaceuticals and telecoms.


PTFE is commonly known as Teflon? (owned by Chemours) and offers remarkable nonstick properties in cookware applications such as kitchen pans and baking trays.

Therefore, there are a series of products like PTFE Liners, PTFE Baskets, PTFE Tray and PTFE Mesh Mat including Non Stick PTFE Liners, Heat Resistant PTFE Liners, Non Stick PTFE Basket, Heat Resistant PTFE Basket, Non Stick PTFE Tray, Heat Resistant PTFE Tray, etc.


PTFE is in rods or tubes of any size, or filled with glass, carbon, stainless steel or many other materials to increase wear resistance and strength, whatever your project or build, we are sure to have a material that will work for you.


The Main Properties of PTFE

If you were trying to invent a highly flexible, chemical resistant, thermal resistant, non-stick and electrically resistant material, and it hadn’t already been done, you’d be hoping you could come up with a material somewhere nearly as good as PTFE is in these areas.


PTFE's melting point is around 327°C, and pure PTFE is almost totally chemically inert, highly insoluble in most solvents or chemicals, and thermally stable enough to be used between - 200 degrees C and +260 degrees C without degrading.


Other useful PTFE properties are its high flexural strength, even in low temperatures, high electrical resistance and dielectric strength, resistance to water (owing to fluorine's high electronegativity), and low coefficient of friction. PTFE's density is also very high, at 2200 kg/m3.


In fact, beyond reaction to some chemical agents and solvents (for example, chlorine trifluoride, cobalt(III) fluoride, xenon difluoride or elementary fluorine if at a high pressure and temperature), the only factor to be taken into consideration when using PTFE is that it does not have a good resistance to high energy radiation, which will cause breakdown of the PTFE molecule.
