Abstract

Although the addition of precipitated silica confers peculiar mechanical properties to rubber compounds enabling its application in several areas, Its incorporation process is extremely complex due to the difficult dispersion of silica in the elastomeric matrix, equipment wear and risk to the operators. The silica sequential precipitation process from any alkali silicate in an emulsion of latex of any origin not only enables the homogeneous distribution of silica in the elastomeric matrix, but also decreases the costs from the reduced wear of the rubber processing equipment and reduced production time, since the silica is already homogeneously incorporated into the matrix.
