BOSTON -- Cabot Corp. will expand production capacity by 25 percent at its fumed silica facility in Barry, Wales. The expansion is expected to be completed in 2012 and is part of a three-year plan to increase Cabots global fumed metal oxide capacity by 35 to 40 percent.

The project is an extension of Cabots long-term partnership with Dow Corning, and will help meet rising global demand for silicones, which is expected to continue to grow at 5 to 10 percent per year over the coming decade. Cabot and Dow Corning have worked closely together in Barry since 1991, when Cabot built its fumed silica facility adjacent to Dow Cornings silicone monomer plant. As part of a highly interdependent and collaborative "fence-line" relationship, Dow Corning provides Cabot with silanes, which are converted to fumed silica for Dow Cornings compounded silicones applications. Cabot and Dow Corning have a similar "fence-line" relationship in Midland, Mich.

"For over 30 years, weve built a long-term partnership with Dow Corning and demonstrated that we are committed to helping them grow," said Sean Keohane, VP - Performance Segment, Cabot. "This expansion represents a natural extension of our successful relationship."

"This expansion is an example of the continued spirit of partnership between the two companies," said James Whitlock, Senior VP and GM - Core Business, Dow Corning. "We look forward to working together with Cabot on future business opportunities."

Fumed silica is an ultra-fine, high-purity particle used as a reinforcing, thickening, abrasive, thixotropic, suspending, or anti-caking agent. The material is highly versatile and used in a wide-range of end-market applications for the automotive, construction, microelectronics and consumer products industries. Fumed silica helps improve the performance of adhesives, sealants, cosmetics, inks, toners, silicone rubber, coatings, polishing slurries, and pharmaceuticals.

Cabot currently has six fumed silica manufacturing facilities globally, including two in the United States (Tuscola, Ill., and Midland, Mich.) two in Europe (Barry, Wales and Rheinfelden, Germany) and two in Asia (Jiangxi Province, China and Mettur, India).
