Abstract

The invention relates to granulates based on silicate fillers, the surface of which was modified with organosilicon compounds, a process for manufacturing the granulates by spraying a suspension of these fillers together with the organosilicon compounds in a spray granulator and the use of the granulates in vulcanizable rubber mixtures.
