Cabot increases fumed silica capacity in China

ERJ staff report (DS)

Boston, Massachusetts -- Cabot Corp. and China National Bluestar (Group) Co. Ltd. are to triple fumed silica capacity at the companies' joint venture plant in Jiangxi Province, China.

The Jiangxi site will progressively increase capacity to 15,000 tonnes of fumed silica from 5000, with the potential to increase by a further 5000 tonnes. In addition, it will manufacture a wide range of products for multiple applications. The full expansion to more than 15,000 metric tons, is scheduled to be on stream at the end of next year. The new capacity will come on stream in stages, with the first phase on stream this year.

The project will produce fumed silica using Cabot's world-class manufacturing technology and utilizing the methyltrichlorosilane byproduct from Bluestar's silicones monomer production. Bluestar's Xinhuo plant will then recycle the hydrogen chloride byproduct from the production of fumed silica as the raw material in the manufacturing of methyl chloride for their silicones monomer production.
