The Silicas segment is led by Evonik Resource Efficiency GmbH and brings together Evonik’s activities in specialty chemicals for industrial applications. Abandoned Application number US09/740,039 Inventor Gunther Michael of SiO2. Evonik is a leading global manufacturer of silica. Hydrophobic fumed silica, which Evonik markets under the brand name Aerosil, stands out for its low moisture absorption and excellent dispersibility. SIPERNAT® D 10 by Evonik is a milled, synthetic, amorphous, hydrophobic silica. It has a shelf life of 24 months. Evonik Industries will invest an amount in the low double-digit million euro range to expand its Rheinfelden facility, Germany, which further processes hydrophilic silica to a hydrophobic variety. AEROSIL® R 976 is a hydrophobic fumed silica aftertreated with DDS (Dimethyldichlorosilane). Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) It exhibits high methanol wettability, low surface area, high effectiveness and ease of dispersion. Therefore, as all minerals, it is not biodegradable, but belongs into a natural cycle. With this, the specialty chemicals company can now serve the high demand for fumed silicas marketed under the AEROSIL® brand. The group will invest an amount in the low double-digit million euro range to expand its Rheinfelden facility, which further processes hydrophilic silica to a hydrophobic variety. AEROSIL® hydrophobic fumed silica is used as an additive in a variety of coatings to optimize rheology during processing, as reinforcement of silicone elastomers and leads to excellent water-repelling properties and improved corrosion protection. Evonik SIPERNAT® D 17 Silica Powder. Evonik is a leading supplier of hydrophobic silica, the key ingredient in creating “dry water.”. 60 % and indicates its highly hydrophobic character. The hydrophobic nano silica (Aerosil®R812) was kindly supplied by Evonik (Hanau, Germany) with spe- cific area of 260±30 m 2 g –1 and average particle size 7
