Abstract
Base compositions for silicone compositions with viscosity <500,000 mPas are continuously produced by, in a first stage, homogeneously mixing and kneading organopolysiloxanes (A) and prehydrophobized oxidic reinforcing fillers (B) in a continuous kneading cascade with kneading chambers arranged alongside one another, and in a second downstream stage, the compositions produced in the first stage of the process are subjected to aftertreatment in a mixing apparatus where the compositions have been subjected to a mixing procedure with introduction of shear force.
