Japanese firm Sumitomo Seika says its super absorbent polymer (SAP), Aqua Keep, has been well received by the market and to meet the increased demand for Aqua Keep, it has steadily increased its production capacity. Anticipating a continued robust growth, the company has decided to further expand its capacity by constructing a new train at Himeji Works in Himeji City, Hyogo, Japan. The train will add 40,000 metric tons per year, bringing the total annual production capacity for Aqua Keep at Himeji Works to approximately 210,000 metric tons. The new train is scheduled to start its operation in April 2015. An additional product warehouse will be built on the site in conjunction with this capacity expansion. The investment amount for the whole project is estimated to be about 6 billion yen ($61 million).
