TOKYO (Sept. 24)—JSR Corp. is upgrading is business forecast for its fiscal year ending March 31, partly as a result of better than expected sales of synthetic rubber to the tire industry. The performance of JSR's Elastomer Business was among a number of factors that prompted the group to raise its forecast for earnings by 33 percent to more than $140 million and sales by 2.3 percent to $2.4 billion. The estimate replaces the group's previous forecast issued April 28. At the same time, JSR—formerly Japan Synthetic Rubber—is expanding solution-SBR capacity at its Yokkaichi, Japan, plant by 40 percent to 35,000 metric tons through improvement in production technology and production facilities. The company—citing steady growth of global demand for S-SBR used for better fuel economy and high-performance tires—also has contracted Dow Europe GmbH to make S-SBR in Europe at Dow's Schkopau, Germany, plant.
