International. Earlier this month, Evonik Industries officially opened a new production line for the manufacture of surface-treated pyrolysis silica under the trade name Aerosil.
The new line will be located in Rheinfelden, Germany, which will increase its global production capacity of these products by 25%. According to the company, this product will improve the properties of high-performance adhesives, sealants and industrial resins, as well as varnishes and paints.
The key factor behind the growing demand for these chemicals is the development of resource-efficient products and technologies. Market trends, including the development of renewable energy sources, and the automotive industry's trend away from mechanical fasteners in favor of higher performance will be supported by this expansion. Other important applications using silica grade specialties include antifoaming, plastic, and toner products.
Among other qualities, the special pyrolysis silica grades performed by Evonik optimize the rheology, viscosity and thixotropy of liquid and gel-type formulations, as well as the suspension properties of pigments and filler materials they contain. They also increase the flow rate of powdered products and prevent agglutination during production and storage.
