BASF
Geismar MDI production facility
BASF inaugurated a new methylene diphenyl diisocyanate production facility at its Geismar, Louisiana, Verbund site, completing a roughly $1 billion expansion that nearly doubles annual site capacity to approximately 600,000 metric tons.
The November 11 inauguration completed the third and final phase of BASF's Geismar MDI expansion. BASF says the new upstream units and splitter strengthen a locally integrated North American supply of MDI, a polyurethane input used in construction, appliances, transportation, automotive, footwear and furniture. The project is BASF's largest wholly owned U.S. investment to date, and the release describes the facility as inaugurated and the expansion as completed on time.
