Abstract:
The present invention relates to a hydrophobic, fumed silica which is obtained by milling a fumed silica which has fixed dimethylsilyl and/or monomethylsilyl groups on the surface due to silanization; and to a process for the preparation of the silica according to the invention, and to silicone rubber materials containing the silica according to the invention.
