In 1938, a New Jerseyan by the name of Roy Plunkett accidentally invented PTFE when he was trying to make a new chlorofluorocarbon (CFC) refrigerant -- which would typically be referred to as "freon", the trade name for such a substance. As the story goes, the tetrafluoroethylene gas stopped flowing before the bottle's weight indicated that the bottle was "empty". Naturally, Plunkett was curious as to why the bottle suddenly had weight that it shouldn't. Eventuallly, he sawed the bottle in hald and found that it was coated with a white and strangely slippery material. It turns out that the chemicals in the bottle had been polymerized when the iron from the inside of the container acted as a catalyst. Shortly after, in 1945 -- polytetrafluoroethylene was known by the trademarked named,"Teflon"
