The second phase of a pyrogenic silica plant in China is under construction by Dow Corning Corp. and Wacker Chemie AG. The pyrogenic silica plant, along with a siloxane plant, are key facilities of an integrated silicone manufacturing site developed by both companies at Jiangsu Yangtze River Chemical Industrial Park in Zhangjiagang. The materials produced at the facilities are used extensively in the beauty and personal care, power, construction and automotive industries. Covering an area of approximately 10.7 millon ft2(1 million m2), the site is China’s largest facility of its kind.

The overall nameplate capacity for both siloxane and pyrogenic silica, including the second-phase silica plant, is expected to be approximately 210,000 metric tons per year. Both companies also own and manufacturing plants for finished silicone products at the Zhangjiagang site. Marketing and sales are undertaken independently by each company.
The corporate headquarters of Dow Corning Corp. is located in Midland, Mich. Wacker Chemie AG is headquartered in Munich.
