Thermoplastic, fully fluorinated polymer used as solid lubricant and thickener for greases. The white coloured polymer is well known under the brand name Teflon® and shows excellent resistance against agressive chemicals and solvents as well as humidity and UV radiation. Due to the plain and slippery surface, a lot of substances are repelled from the material and PTFE particles are used in greases as thickener and solid lubricant, especially in plastic lubrication.
