How was Teflon discovered?
. In the 1960’s, Dr. Roy Plunkett, a Dupont chemist, was working on a project to find alternate materials for cooling purposes. He had stored some tetrafluorethylene gas (similar to freon) in a container and left it overnite. When he returned in the morning, the gas was gone and in its place was a white wax-like substance. Teflon had been discovered. . Properties of Teflon . PTFE is an extaordinary material. Some say that it is the most useful material known to man. This is because it has a combination of properties that are very hard to find. Its four great properties are: 1. very low coefficient of friction, 2. highly inert, 3. high melting point, 4. wonderful electrical properties. These properties are due to its unique molecular structure.
