PTFE Sheet and Film
PTFE plastic sheet comes in a roll in the .005 - .020 thickness. If you order more than 1 pc, it will be cut from a roll. In thicknesses greater than .020, we stock a 48 x 48 and cut to the increments you see listed. From these sizes, ANY size can be cut or machined!
PTFE has the highest melting point and is capable of continued service at 500F(260 C). FEP is a melt processible resin capable of continued service at 400F(204 C). PTFE products are used as gasket and packing materials in chemical processing equipment; as electrical insulation for maximum reliabillity; and in bearings, seals, piston rings and other mechanical applications, especially those requiring anti-stick characteristics.Please note: ALL PTFE sheet 0.093" and under will be ROLLED for shipment to save on UPS charges. If you are familiar with PTFE, you understand it's not flat in these thicknesses.
When you receive the material, simply re-roll in the opposite direction to restore some flatness to the sheet/film.
PTFE was the first fluorocarbon. It is the most chemically resistant plastic known. Only a few chemicals react with it. Its mechanical properties are low compared to other engineering plastics, but its properties remain at a useful level over a great temperature range — from -400 to 500°F (-240 to 260°C). Mechanical properties can be improved by the addition of fillers such as glass fiber, carbon, graphite, molybdenum disulfide and bronze. PTFE has excellent thermal and electrical insulation properties. And, it has a low coefficient of friction. It is difficult to make anything adhere to PTFE. A material may stick to it, but the material can be peeled off or rubbed off.
