  • 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.
    Type: Grant
    Filed: March 12, 1997
    Date of Patent: September 26, 2000
    Assignee: Degussa-Huls AG

  • Surface modified synthetic, silicatic filler, a process for its production and its use
    Patent number: 4704414
    Abstract: The invention is directed to the modification of synthetic, silicatic fillers with water insoluble sulfur containing organosilicon compounds. For this purpose, the fillers are converted into an aqueous suspension and treated with the organosilicon compounds, optionally in the presence of an emulsifier. The thus modified filler in vulcanized rubber mixtures results in a clear improvement in the industrial properties of the rubber.
