South Korea’s Hyosung Corporation has taken its second license for the Unipol polypropylene technology now owned by US chemical producer W.R. Grace. The process will be used in the company’s new 200,000 t/y plant scheduled to start up in at Ulsan, Korea in 2017.

Grace, which acquired the Unipol process with its $500 million takeover of Dow Chemical’s Polypropylene Licensing and Catalysts business segment in 2013, regards itself as a leading supplier of polyolefin catalyst technology. The company claims to have the broadest portfolio of any independent PE/PP catalyst manufacturer.
