Part 3/11:
The military soon took an interest in Teflon during World War II as DuPont worked on the Manhattan Project. Teflon proved invaluable as a non-reactive material against corrosive chemicals used in the refinement of uranium and plutonium. DuPont capitalized on the military’s demand, trademarking the name 'Teflon' in 1944. The robust nature of Teflon found applications far beyond refrigerants; it became integral in manufacturing gaskets, seals, and coatings for military gear and equipment.
