DuPont

DuPont de Nemours, Inc., commonly shortened to DuPont, is a company headquartered and organized in Delaware that produces products for the healthcare, water, construction and industrial markets. It was formed in 1802 by French-American chemist and industrialist Éleuthère Irénée du Pont de Nemours. The company operates two divisions: Healthcare & Water Technologies (47% of 2025 revenues), which produces medical packaging such as Tyvek packaging and Tychem protective suits as well as Amberlite ion exchange resins, Filmtec reverse osmosis and nanofiltration elements and Inge and Itegratec ultrafiltration modules; and Diversified Industrials (53% of 2025 revenues), which produces products for repair‑and‑remodel construction such as Tyvek house wrap, Styrofoam insulation, Corian, Vespel shapes and parts, Molykote lubricants, Betaforce, and Betaseal. The company played a major role in the development of the U.S. state of Delaware and first arose as a major supplier of gunpowder. DuPont developed many polymers such as Vespel, neoprene, nylon, Corian, Teflon, Mylar, Kapton, Kevlar, Zemdrain, Nomex, Tyvek, Sorona, viton, Corfam and Lycra in the 20th century, and its scientists developed many chemicals, most notably Freon (chlorofluorocarbons), for the refrigerant industry. It also developed synthetic pigments and paints including ChromaFlair. DuPont was the largest chemical company by sales; its chemicals operations were spun-off into Chemours in July 2015. In August 2017, DuPont merged with the Dow Chemical Company and renamed itself DowDuPont. After 18 months, it spun off its material science divisions into a new corporate entity bearing Dow Chemical's name and the agribusiness divisions into Corteva; DowDuPont reverted its name to DuPont and kept the specialty products divisions.
