Developmental products from the Business Line Silica


Evonik continuously develops new products for its customers throughout the world based on its many technologies for the production and modification of fumed silicas and metal oxides. 


Evonik presents a selection of its latest developmental products on this website. All developmental products are marked with the prefix VP and are generally already being produced on a pilot scale. Whether they will ultimately be commercialized or not depends on their success in the market. Do you have other ideas or do you need a very special product for your application? Then please get in touch with us.

Hydrophilic fumed specialty silicas

Evonik is the leading producer of fumed specialty silicas marketed under the brand name AEROSIL®. One special product development in this category is VP DOX 110, an aluminum-doped fumed silica with a low surface area and structure, which is especially suitable as a carrier, for example in the area of catalysis.

Titanium dioxide-based products

With our AEROSIL® process we can specifically produce and modify fine-particle titanium dioxides with different specific surface areas and chemical compositions. Potential applications for these include use as raw materials for catalysts and UV filters and as additives for toners and plastics.
