History PTFE was accidentally invented by Roy Plunkett of Kinetic Chemicals in 1938. While Plunkett was attempting to make a new CFC refrigerant, the perfluorethylene polymerized in its pressurized storage container, with the iron from the inside of the container acting as a catalyst. Kinetic Chemicals patented it in 1941 and registered the Teflon trademark in 1945. By 1950, DuPont had acquired interest in Kinetic Chemicals and was producing over a million pounds (450 tons) of Teflon per year in Parkersburg, West Virginia. In 1954, French engineer Marc Grgoire created the first pan coated with Teflon non-stick resin under the brand name of Tefal after his wife urged him to try the material he had been using on fishing tackle on her cooking pans. In the United States, Kansas City, Missouri resident Marion A. Trozzolo, who had been using the substance on scientific utensils, marketed the first US-made Teflon coated frying pan, “The Happy Pan,” in 1961. An early advanced use was in the Manhattan Project as a material to coat valves and seals in the pipes holding highly reactive uranium hexafluoride in the vast uranium enrichment plant at Oak Ridge, Tennessee, when it was known as K-25. Properties PTFE is often used to coat non-stick frying pans as it is hydrophobic and possesses fairly high heat resistance. PTFE is a white solid at room temperature, with a density of about 2.2 g/cm3. According to DuPont its melting point is 327C (621F), but its properties degrade above 260C (500F). PTFE gains its properties from the aggregate effect of carbon-fluorine bonds, as do all fluorocarbons. The coefficient of friction of plastics is usually measured against polished steel. PTFE’s coefficient of friction is 0.1 or less, which is the second lowest of any known solid material (diamond-like carbon being the first). PTFE’s resistance to van der Waals forces means that it is the only known surface to which a gecko cannot stick. PTFE has excellent dielectric properties. This is especially true at high radio frequencies, making it suitable for use as an insulator in cables and connector assemblies and as a material for printed circuit boards used at microwave frequencies. Combined with its high melting temperature, this makes it the material of choice as a high-performance substitute for the weaker and lower melting point polyethylene that is commonly used in low-cost applications. Its extremely high bulk resistivity makes it an ideal material for fabricating long life electrets, useful devices that are the electrostatic analogues of magnets. Because of its chemical inertness, PTFE cannot be cross-linked like an elastomer. Therefore it has no “memory,” and is subject to creep, also known as “cold flow” and “compression set”. A little bit of creep allows PTFE seals to conform to mating surfaces better than most other plastic seals. Too much creep, however, and the seal can be compromised. Compounding fillers control unwanted creep and improve wear, friction, and other properties. Sometimes metal springs apply continuous force to PTFE seals to give good contact, while permitting some creep. Due to its low friction, it is used for applications where sliding action of parts is needed: plain bearings, gears, slide plates, etc. In these applications it performs significantly better than nylon and acetal; it is comparable to ultra high-molecular weight polyethylene (UHMWPE), although UHMWPE is more resistant to wear than Teflon. For these applications, versions of Teflon with mineral oil or molybdenum disulfide embedded as additional lubricants in its matrix are being manufactured.
