DuPont

DuPont de Nemours, Inc., commonly shortened to DuPont, is an American multinational chemical company formed in 1802 by French-American chemist Éleuthère Irénée du Pont de Nemours, initially as a gunpowder supplier with significant influence on Delaware's development. It developed numerous 20th-century polymers (e.g., Vespel, neoprene, nylon, Corian, Teflon, Mylar, Kapton, Kevlar, Zemdrain, Nomex, Tyvek, Sorona, Viton, Corfam, Lycra) and chemicals like Freon, as well as synthetic pigments such as ChromaFlair. In the semiconductor supply chain, DuPont provides critical materials including dielectrics, adhesives, and photoresists. Following a 2015 agreement, DuPont merged with Dow Chemical to form DowDuPont in 2017, which spun off materials science into Dow Inc. and agribusiness into Corteva; DowDuPont then reverted its name to DuPont de Nemours, Inc., retaining the specialty products division.
