By David Reed, UT EditorMidland, Michigan-With effect from 15 March, Dow will increase the price of its toluene diisocyanate (TDI) by $0.08/pound (about €0.13/kg). The TDI price adjustment applies to all market segments and end-use applications in the US and Canada, the firm said, in a 22 Feb statement."This price increase is necessary in order to help restore margins for our TDI product offering to more sustainable levels," said Charles Reardon, North American product market manager, Dow Polyurethanes, in the statement. "Rising energy and raw material costs continue to have a dramatic impact on our production costs and margins," he explained.Dow says it is the world's largest producer of polyether polyols, a leading producer of quality aromatic isocyanates (such as MDI (methylene diphenyl diisocyanate) and TDI), and a major supplier of propylene oxide, an essential component of polyether polyols. The firm's products are used in making flexible and rigid polyurethane foams, as well as adhesives, sealants, coatings, and elastomers, used in a wide variety of applications."
