To satisfy growing demand for polycarbonate in Asia, Covestro is doubling production capacities for the high-tech plastic from 200,000 to 400,000 metric tons per year at its site in Shanghai, China. Two new world-scale production lines for polycarbonate resins were inaugurated there on Wednesday, with state-of-the-art technologies and energy saving processes. This thrusts Covestro into becoming the world’s largest producer of such resins.
