  • FLAKES HYDROPHOBIC THROUGH-AND-THROUGH AND COMPRISING PYROGENICALLY PREPARED SILICON DIOXIDE
    Publication number: 20100254876
    Abstract: Hydrophobic flakes comprising pyrogenically prepared silicon dioxide prepared by optionally mixing pyrogenically prepared silicon dioxide with water or another reaction auxiliary and a water repellent, compacting and, optionally after ripening, annealing. The hydrophobic flakes thus produced can be used as a filler in natural rubber and synthetic rubber.
