Deal will combine a large chlor-alkali producer with a major user of chlorine and derivatives
Chemical companies Olin and Huntsman have agreed to a ‘merger of equals’ to form ‘OlinHuntsman’ with a total annual revenue of over $12 billion (£9 billion).
Olin is predominantly a chlor-alkali business, electrolysing salt to produce chlorine and sodium hydroxide, along with derivatives including polyvinyl chloride (PVC) and sodium hypochlorite. It also produces epoxy resins and manufactures Winchester ammunition. Huntsman makes various speciality chemicals and polymer components, as well as epoxides, curing agents and additives. Its largest segment produces methylene diphenyl diisocyanate (MDI) and other polyurethane materials.
