Huber Engineered Materials, a division of J.M. Huber Corp., has announced a price increase for its precipitated silica and silicate products manufactured in North America.  The increase is effective January 1, 2017, or as current contracts allow for direct customers and distributors. The company says the price adjustment of three percent for North America manufactured products is necessary due to increasing costs in raw materials, energy, freight, labor and manufacturing. Huber is a global supplier in silica production, with multiple production sites in North America, Europe and Asia. These produce a variety of silicas and silicates used in consumer, food, industrial, paper and pharmaceutical applications.
