LEVERKUSEN, Germany (Aug. 3) — Bayer MaterialScience A.G.´s Polyurethanes Business Unit has added 36,000 metric tons of annual capacity for methylene diphenyl diisocyanate at its plant in Krefeld-Uerdingen, Germany, bringing its global capacity to more than 1 million tons.
The expansion was achieved by "a number of debottlenecking measures based on process improvements," Bayer said, adding that these "did not require any major investment."
"We want to grow with the market by ensuring an efficient utilization of our available capacities," said Peter Vanacker, head of the Polyurethanes Business Unit, in a prepared statement.
"The recent expansion project is one of several measures that have enabled us to significantly increase our total annual capacity in the last two years," he added.
MDI is an important chemical component in the production of polyurethane foams and elastomers. Rigid insulating foams are used, for example, in the production of refrigerators and freezers, for thermal insulation in the construction industry and in district heating systems. MDI elastomers are used in the footwear, automotive and electrical industries.
