DuPont

DuPont de Nemours, Inc., commonly shortened to DuPont, is an American diversified specialty chemical conglomerate formed in 1802 as a gunpowder mill. It developed numerous polymers (e.g., Kevlar, Nomex, Teflon) and chemicals. 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 later spun off materials science into Dow Inc. and agribusiness into Corteva; the remaining specialty products division reverted to the DuPont name. As of 2025, the company operates two divisions: Healthcare & Water Technologies (47% of revenues), producing medical packaging (Tyvek), ion exchange resins (AMBERLITE), and water filtration elements (FILMTEC, INGE); and Diversified Industrials (53% of revenues), serving construction (Tyvek house wrap, Styrofoam, CORIAN) and industrial markets (Vespel, MOLYKOTE, BETAFORCE).
