Wacker expands pyrogenic silica production capacity

Wacker Chemie AG is increasing its production capacities for HDK pyrogenic silica. To this end, Wacker is expanding an hydrophobic silica specialities plant at its site in Burghausen, Germany. The plant’s capacity will rise by 40% as a result, with capital expenditures on the project amounting to €1.4M.

With work beginning early next year, project completion is expected in Q3 of 2017. Hydrophobic speciality silicas are used in toner powders for printers. They enhance the stability of the end product, as well as its flow and charging properties. Used in speciality adhesives and paints, these kinds of silica permit optimum adjustment of rheological and mechanical properties.

Wacker also produces HDK pyrogenic silica at Nünchritz in Germany and Zhangjiagang in China.
