Abstract
Uniquely dispersible precipitated silica particulates, e.g., beads, powders and granulates/extrudates, very well suited for the reinforcement of elastomer/rubber matrices, e.g., tires for the automotive industry, have characteristic particle sizes, BET and CTAB specific surface areas, DOP oil absorption values, total pore volumes and pore size distributions, and reduced degree of attrition.
