Global Coverage

In 2011, Stepan made two strategic acquisitions in both Asia and Central Europe. To help grow our surfactants franchise in Asia, we acquired a 100,000 ton-per-year methyl ester plant in Singapore, expected to become a global chemical manufacturing hub for the Asia-Pacific region. We also purchased a state-of-the-art polyol chemical manufacturing facility in Brzeg Dolny, Poland, with 25,000 metric tons of blending capacity. We have also increased our capacity around the world by optimizing and streamlining our processes. Our neutralization capacity in Brazil, increased ownership (now 100%) in the Philippines and our larger polyol plant in Germany will make Stepan a stronger global provider for a multinational customer base.  In 2013, Stepan completed the acquisition of Bayer MaterialScience's North American Polyester Resins business.  This acquisition provides a significant line extension to our core business and the acquired Columbus, Georgia USA facility provides 20,000 MT of capacity.  The acquired business has been integrated into Stepan's existing Polymer business and complements our three existing innovation research centers and four polyester polyol manufacturing facilities.
