“We’re pursuing a clear growth strategy for our silica business. With the additional capacities, we’re ensuring supply for our customers over the long term,” said Harald Schwager, deputy chairman of Evonik’s executive board. As part of Smart Materials, silica belongs to one of Evonik’s four strategic growth engines with above-average market growth. The growth of the global market for fumed silicas is expected to exceed 4% annually.
Along with the market for hydrophilic fumed silica, demand is also growing for specialty hydrophobic silicas. The existing plant in Antwerp has been upgraded such that hydrophilic fumed silica can be given hydrophobic properties by special post-treatment. Evonik therefore now produces hydrophobic AEROSIL at a second European site in addition to Rheinfelden, thus servicing continued high demand.
