Evonik And Wynka Start Fumed Silica Production In China

Evonik Wynka, a joint venture between Evonik and Chinese chemical company Wynka , has set up a fumed silica production plant at the Zhenjiang New Material Industry Park in Jiangsu province in China. 

The production plant is Evonik's first fumed silica production plant in China and will produce the material under the 'Aerosil' brand name. The material is used in industrial applications such as silicones, coatings, adhesives and sealants due to the material's features such as thickening, thixotropy, anti-precipitation and matting.

The joint venture will enable resource sharing between the companies and produce high-value fumed silica products, making use of monomer by-products methyltrichlorosilane and chlorosilane from Wynka using Evonik's product technology. The by-product of fumed silica's production, hydrochloric acid, will be utilised as raw material at Wynca's Zhenjiang Site. 

Dr Claudine Mollenkopf, Head, Evonik Silica business line, said, "I am excited to witness the cooperation between Evonik and the Chinese partner Wynca. The joint venture will be a strong complement to Evonik’s global presence in fumed silica. We expect win-win results through leveraging the expertise of both parties in silicon materials." (TT)
