Olin Corporation operates globally through three primary business segments: Chlor Alkali Products and Vinyls, Epoxy, and Winchester. The Chlor Alkali segment is a leading producer of basic industrial chemicals such as chlorine, caustic soda, and related derivatives used in various manufacturing processes. The Epoxy segment manufactures a full range of epoxy materials and precursors, including aromatics and liquid or solid epoxy resins. The Winchester segment is a prominent manufacturer of sporting ammunition, reloading components, and small-caliber military ammunition. Headquartered in Clayton, Missouri, Olin's vertically integrated structure and strategic acquisitions, such as the 2015 purchase of Dow Chemical's chlor-alkali and epoxy businesses, have solidified its position as a major player in the global commodity chemicals market.
