Comparison of Teflon and plastic
From a boiling bath of hot sulfuric acid, a laboratory technician lifts two rods of plastic. One has charred and deteriorated. The other-a rod of DuPont's new Teflon tetrafluoroethylene resin-is not affected at all by the highly corrosive hot acid. Teflon resists the most corrosive acids and solvents to a degree unequaled by any other plastic. It is not attacked even by aqua regia which dissolves gold and platinum.
