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 Teflon tetrafluoroethylene resin-is not affected at all by the highly corrosive hot acid. Teflon resists the most corrosive acids and solvents. It is not attacked even by aqua regia, which dissolves gold and platinum.
DuPont gives financial assistance to Delaware Technical and Community College in Wilmington, Delaware for minority and female high school students to take engineering courses at Deltech and when qualified, receive financial assistance for going on to Delaware State or University of Delaware.
