The D7000 Donor catalyst is designed specifically to optimize high-melt impact copolymer polypropylene resins, such as the plastic used in automotive interior and food contact applications. The catalyst is said to smooth and speed transitions between product grades and improve performance characteristics of finished products. In addition, the catalyst allows the reduced use of peroxide, which lowers resin manufacturing costs. Commercial trials with the catalyst have shown improved process efficiency and lower costs, says the manufacturer. — Dow Chemical Co., Midland, Mich.
