Evonik and Wynca Begin Construction on Fumed Silica Plant in Zhenjiang

The joint venture between Evonik and the Chinese company Wynca — Evonik Wynca (Zhenjiang) Silicon Material Co., Ltd. has officially started the construction on a new fumed silica plant in Zhenjiang, Jiangsu Province, China. Scheduled to become operational in 2021 with a projected annual output of 9,000 metric tons, the new plant will produce fumed silica marketed under the name AEROSIL®, in order to fulfil the market demand for silicones, coatings and paints, modern adhesives and gel batteries in China, the companies stated.

“As a kind of Smart Materials, silica belongs to one of the four strategic growth engines identified by Evonik because of its rapid market growth and extensive applications. As our first fumed silica plant in China, the new plant in Zhenjiang will further improve the global production network of AEROSIL® and ensure a more solid supply for Chinese customers,” said Andreas Fischer, board member of Evonik Resource Efficiency GmbH.

According to the companies, the joint venture will combine Evonik’s advanced product technology with the silicone industry value chain formed by Wynca, building a production facility for AEROSIL® fumed silica products by utilizing chlorosilanes from Wynca. The integrated production loop is expected to make full use of by-products from each side and achieve perfect resource recycling and synergies among organic silicon monomer, chlorosilane and fumed silica production, the companies added.

“Evonik regards Asia, especially China, as an important growth region. China is currently undergoing an overall industrial transformation and upgrade. These changes will generate significant market opportunities for Evonik. The establishment of the new plant will further expand our business presence in China’s fumed silica market. Meanwhile, it’s also our pleasure to work closely with Wynca as our strong local partner, and to jointly explore this attractive market,” said Dr. Claas Klasen, president of Evonik’s Asia Pacific North region.
