CLEVELAND (Oct. 2)—B.F. Goodrich´s Polymer Additives and Specialty Plastics Group will increase the price of its Estane-brand thermoplastic polyurethanes and Estaloc-brand reinforced engineering thermoplastics by 5 percent in North America due to increases in operational and raw material costs and declining margins, a Sept. 11 news release said. In addition, the minimum order quantity will be increased from 50 to 500 pounds per product. The increase, which will go into effect Oct. 15, is the first TPU price increase initiated by the company since November 1997. Estane TPUs contain elastomeric materials that bridge the gap between flexible rubber and rigid plastics. Estaloc RETPs are based on Estane TPU technology and are reinforced for higher stiffness and provide strength to withstand a variety of tough applications and environments, the release said. In April 2000, B.F. Goodrich made plans to divest its Performance Materials Segment, including TPUs and elastomers, by the end of the year to concentrate on its Aerospace and Engineered Industrial products operations.
