Play-Doh was originally called Rainbow Modeling Compound and used to clean wallpaper. A NJ nursery school teacher found it was fun to use as a toy.
Polytetrafluoroethylene (commonly known as teflon), discovered by Roy Plunkett at DuPont. 1941: Polyethylene terephthalate (PET) is discovered at the Calico Printers' Association in Britain. Expanded polystyrene is first produced. [6] 1950: DuPont begin the manufacture of polyester. 1951
During Prohibition, enforcing the nation’s liquor ban was a game of cat and mouse. Smugglers, speakeasies, and bootleggers found creative ways to dodge the law, while federal agents scrambled to ...
In 1938, polytetrafluoroethylene (DuPont brand name Teflon) was discovered by accident by a recently hired DuPont Ph.D., Roy J. Plunkett. While working with tetrafluoroethylene gas to develop refrigerants, he noticed that a previously pressurized cylinder had no pressure remaining. In dissecting the cylinder, he found a mass of white solid in a ...
The modern non-stick pans were made using a coating of Teflon (polytetrafluoroethylene or PTFE). PTFE was invented serendipitously by Roy Plunkett in 1938, [3] [4] while working for a joint venture of the DuPont company. The substance was found to have several unique properties, including very good corrosion-resistance and the lowest ...
