Cabot expands UK fumed silica production

US-based specialty chemicals and performance materials company Cabot has expanded fumed silica production capacity by 25% at its facility in Barry, Wales, UK.

The expansion project, which forms part of a Cabot's three-year plan started in 2011 to increase global fumed metal oxide capacity by 35 to 40%, is an extension of the company's long-term relationship with US-based Dow Corning.

With the expansion, Cabot can use various silane raw materials to make a broader portfolio of products to meet silicones and other market needs.

Ultra-fine, high-purity particle fumed silica is used as a reinforcing, thickening, abrasive, thixotropic, suspending, or anti-caking agent for use in end-market applications for the automotive, construction, microelectronics and consumer products industries.

"With the expansion, Cabot can use various silane raw materials to make a broader portfolio of products."

Fumed silica is also expected to improve the performance of silicone rubber, adhesives, sealants, cosmetics, inks, toners, coatings, polishing slurries and pharmaceuticals.

Cabot performance materials senior vice president Sean Keohane said: "The expansion of Barry marks another milestone in our long-term relationship with Dow Corning and demonstrates our commitment to support their growth."
