ExxonMobil adds halobutyl capacity in Baytown, Tx

Houston, Texas- ExxonMobil Chemical is to increase halobutyl manufacturing at its plant in Baytown, Texas. The US facility will increase capacity to produce Exxon Bromobutyl rubber by 60 percent by modifying existing equipment and adding new equipment. The company did not indicate how large the facility is, but the IISRP indicates that the unit has capacity for 71 000 tonnes / year of all butyl rubber materials. Bromobutyl uses ordinary butyl rubber as a raw material and adds bromine groups to make a more effective inner liner material.

ExxonMobil Chemical is a major supplier of halobutyl rubber to the global tyre industry and has expanded its capacity to produce this polymer by 80 percent in the past decade. In 2002, the company completed an expansion at Baytown that quadrupled its halobutyl capacity. Japan Butyl Co. Ltd., an ExxonMobil Chemical joint venture, recently completed an expansion that increased its halobutyl production capacity to 70 000 tons a year to meet growing demand in Asia Pacific. In another expansion at the Baytown butyl plant, the company is doubling its capability to produce proprietary Exxproâ„¢ specialty elastomer, used for new high air barrier technologies for tire inner liners. Announced in 2005, the project is targeted for completion by year end.
