Tailor made Silica/Silane-Systems

Precipitated Silica – Morphology Control

Precipitated silica, especially in combination with bifunctional organosilanes, is one of the most important active filler, filler system respectively, that is used in the rubber industry and especially in passenger car tire tread compounds. Despite the fact that there are already many different silica having a broad range of different specific surface areas, the variety of cluster sizes in the nanometer range is rather low in contrast to the broad range of available carbon black structure variations. more...
