By Patrick Raleigh UT On-line news editorMiddlebury, Connecticut-Crompton Corp.'s Urethanes business has added $0.09/pound to the selling price for its Fomrez polyester polyol range in the US and Canada, as of 1 May. The increase is in response to a sustained rise in raw material, manufacturing and energy costs since last year, according to Ron Matula, Crompton's Fomrez polyester polyol business manager in the Americas. "This increase will allow us to continue supplying our valued customers with the quality and service they have come to expect from Crompton's Urethanes business," Matula said in a press statement. Fomrez polyester polyols are used in the manufacture of elastomers, thermoplastic urethanes, adhesives, coatings, flexible foam, and shoe soles."
