Silane-modified oxidic or siliceous filler, process for its production and its use

摘要

Silane-modified oxidic or siliceous filler with a bead fraction below 75 mum of less than 15 wt. % and a median particle size distribution between of 150 to 500 mum, 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.
