  • Silane-modified oxidic or siliceous filler, process for its production and its use
    Patent number: 7186768
    Abstract: Silane-modified oxidic or siliceous filler with a bead fraction below 75 ?m of less than 15 wt. % and a median particle size distribution between of 150 to 500 ?m, which is produced by the reaction of at least one microbeaded or microgranular, oxidic or siliceous filler in a compressed gas with at least one silane. The silane-modified oxidic or siliceous fillers are used in rubber compounds.
    Type: Grant

  • Low-dust, well dispersible granulates based on silicate fillers modified with organosilicon compounds
    Patent number: 6123762
    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.
