Attorneys at Hartley LLP were appointed co-lead counsel for plaintiffs by the court in this nationwide antitrust MDL case. The complaints asserted a class action on behalf of companies in the United States that purchased the input chemicals to manufacture polyurethane products. Polyurethane is made by the combination of a polyol and an isocyanate. The two major polyols used are polyester polyols and polyether polyols. This first Urethanes class action concerned a conspiracy to fix and raise the prices of polyester polyols manufactured by Crompton/Chemtura, Bayer, Rhein Chemie and Uniroyal Chemical. The case settled for over $33 million.
