MIDLAND, Mich. (Dec. 19)—Dow Chemical Co. will idle its Train 1 toluene diisocyanate production line at its Texas Operations in Freeport, Texas, by the end of January. The line, which produces 130 million pounds of TDI annually, is one of two production trains in Freeport. Other company plants in Porto Marghera, Italy; Camacari, Brazil; and Freeport will pick up production. The shutdown could impact 15 jobs, but Dow said it hopes the employees will fill other positions at the site. The firm also has canceled a project to convert its mothballed Train 2 line at Camacari to TDI production from methylene diphenyl diisocyanate output. The company said the moves are necessary to restore margins to acceptable levels.
