Zusammenfassung:Particles P and methods of making the same. The particles P are composed of a core K comprising crosslinked silicone elastomer composition X and of a shell H of silica S. Where the core K includes a reinforcing filler F which is selected from pyrogenic or precipitated hydrophobic silicas having DIN 66131 BET surface areas of at least 50 m2/g and also from carbon blacks and activated carbons and silicone resins.
