TIANJIN, China & BOSTON, Sep 18, 2011 (BUSINESS WIRE) -- Cabot Corporation (NYSE:CBT) will host an opening ceremony today for its new Tianjin masterbatch plant.

Part of the world's largest rubber and specialty carbon black facility, this state-of-the-art plant includes the latest environmental and manufacturing technologies to ensure production of high-quality masterbatches.

"We are excited about this new facility, not only because it's going to be the largest and most cost effective integrated facility, but also because it's going to improve the efficiency and the capability of the Tianjin operations. We appreciate the support of the Tianjin Economic Development Area and China governments in the continuing development of this facility."
