DuPont
American multinational chemical company
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.

Why this record matters
A short description can identify a subject without explaining its stakes. For “DuPont”, the useful work is to connect “american multinational chemical company” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Aug 30, 2026. The linked authority identifier is Q221062. VIAF identifies the subject as 141519150. The Library of Congress control number is n79127804. 4 of 6 selected statements include explicit references; 3 carry qualifiers and 0 use preferred rank. The first chronological checks are 1802, 2025, 2015 and 2017.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
