WILMINGTON, Del. (Oct. 10)—DuPont Dow Elastomers has increased annual capacity for Engage polyolefin elastomers to about 90,000 metric tons through debottlenecking its Freeport, Texas, plant. The move is in line with the firm's plan to raise Engage capacity to 225,000 tons—including the start-up of a new 135,000-ton facility in Plaquemine, La., by late 2002. The capacity expansions are in response to growing demand for Engage products, particularly as modifiers for TPOs in automotive applications, and as ingredients in soft, flexible molded and extruded goods, according to a company statement. The firm also is broadening the Engage product range, offering grades with ultra-low density and high co-monomer levels, as well as higher molecular weights. Some of the new grades are based on ethylene butene, to complement the existing ethylene octene-based products, the company said.
