Syndiotactic PS Is Back

Idemitsu Kosan Co.

Idemitsu Kosan Co. Ltd. of Japan has started to manufacture and sell syndiotactic polystyrene (SPS) compounds in North America. The company has sold SPS under the Xarec brand, primarily in Asia, since 1997. Idemitsu also plans to restart a 5500-ton SPS resin plant in Chiba, Japan, by the first quarter of 2007, according to Tom Fiola, North American business manager. Xarec materials are being compounded by DH Compounding in Clinton, Tenn., and sold through Idemitsu Chemicals U.S.A. Corp., Southfield, Mich. Idemitsu also aims to set up compounding in Europe. Idemitsu decided to expand its sales globally after Dow Chemical, Midland, Mich., opted to discontinue its line of Questra SPS resins in late 2004. Idemitsu Petrochemicals of Japan had licensed Dow in 1995 to make and sell SPS in North America. Idemitsu says its Xarec and Dow's Questra are "essentially identical." SPS is a clear, crystalline engineering thermoplastic made from ordinary styrene monomer with a metallocene catalyst. It offers good heat and chemical resistance for automotive and electrical/electronic parts. Idemitsu offers around a dozen grades that are flame-retardant, glass-filled, platable, or alloyed with standard PS.
