Perstorp, Sweden -- Perstorp is increasing the prices of its HDI (hexamethylene diisocyanate) and IPDI (isophorone diisocyanate) monomers and derivatives (Tolonate and Easaqua) by 8 percent.
The price increases, which take effect 1 Apr 2010, are due to "substantially higher cost of raw materials and utilities," Perstorp said 19 March. (RD)
