TOKYO (May 20, 2009)—Japan Butyl Co. Ltd. will increase its butyl rubber production capacity by 18,000 tons per year at its Kawasaki, Japan, plant.
This expansion will bring total capacity to 98,000 tons per year when the project is completed in late 2010.
Japan Butyl is a 50:50 joint venture between JSR Corp. and ExxonMobil Yugen Kaisha. EMYK is a 100 percent indirect subsidiary of Exxon Mobil Corp. of the U.S.
This expansion will incorporate ExxonMobil's recent advances in process technology. One such new proprietary technology advancement allows for the butyl polymerization reaction, which normally occurs at -95°C, to operate at -75°C.
This technological advancement will provide significant energy and capital investment savings, ExxonMobil said.
