 | | What Roy J. Plunkett had discovered, or possibly invented, was polytetrafluoroethylene (pahl-ee-teh-tra-flor-oh-eth-a-leen), or PTFE (pee-tee-eff-ee), the world's first thermoplastic, and one of the 20th century's true talking frogs. |
 | | In the Spring of 1938, at a DuPont laboratory in Deepwater, New Jersey, Roy J. Plunkett was investigating replacements for the ammonia and sulfur dioxide used in the refrigeration equipment of the day. |
 | | And while TFE, Plunkett's proto-frog and the monomer on which PTFE is built, is a known carcinogen, PTFE itself is almost completely inert. |
