Sumitomo Chemical buys out Trinseo stake in SSPC joint venture

| By Mary Bailey

Trinseo Holding B.V., a wholly owned subsidiary of Trinseo S.A. (Berwyn, Pa.; www.trinseo.com), and Sumitomo Chemical Co. (Tokyo; www.sumitomo-chem.co.jp), have signed a definitive agreement for Trinseo to sell all of its 50% share in their Sumika Styron Polycarbonate (SSPC) joint venture to Sumitomo Chemical for an undisclosed price.  

Sumika Styron Polycarbonate currently produces polycarbonate resins at production facilities in Niihama City, Ehime, Japan, and serves customers and markets throughout Asia.  In addition to the sale of Trinseo’s ownership in the joint venture, the parties have agreed to continue long-term supply of polycarbonate resin to Trinseo’s Performance Plastics businesses and as such will maintain the strategic relationship between SSPC and Trinseo.

“Sumitomo Chemical is a natural owner for this Japan-based polycarbonate plant, and as an industry leader in the region, Sumitomo Chemical is better positioned to manage and deliver value from this asset in the future,” said Tim Stedman, Senior Vice President and Business President for Basic Plastics and Feedstocks, Trinseo.  “At the same time, Asia Pacific continues to be an important growth region for Trinseo, and the company is strongly committed to growing our Performance businesses in the region.”

“We highly appreciate the long-term relationship with Trinseo and respect the decision by them. We will explore opportunities of further expanding polycarbonate business by leveraging technical capabilities we have developed long time, as Petrochemicals & Plastics Sector has a broad product portfolio,” said Tomohisa Ohno, Director and Senior Managing Executive Officer of Sumitomo Chemical.

The transaction is expected to close on January 31, 2017. Terms of the agreement are not disclosed.

Following the close, it is expected that SSPC will operate as a wholly owned subsidiary of Sumitomo Chemical.  SSPC will continue to operate and will be renamed Sumika Polycarbonate Limited after a transitional period.

SSPC was originally formed as Sumitomo Dow Limited in 1996 as a 50:50 joint venture between Sumitomo Chemical Co., Ltd. and The Dow Chemical Company. After Styron (Trinseo) became an independent company in 2010, it assumed Dow’s ownership share in the joint venture, which was renamed Sumika Styron Polycarbonate (SSPC) at that time.
