Continuous process for preparing organo-polysiloxane compositions (A) having a measured viscosity of at least 500 Pas at 25[deg] C, comprises: (a) mixing organo-polysiloxanes and fillers to raw mixtures in a kneading cascade with at least two kneading chambers arranged side by side in series, which respectively contains kneading tools driven in same- or opposite directions, and kneading the raw mixture; and (b) kneading and degassing the crude mixture in a continuously operating double hollows kneader with discharge screw, at 100-250[deg] C. Continuous process for preparing organo-polysiloxane compositions (A) having a measured viscosity of at least 500 Pas at 25[deg] C, comprises: (a) mixing organo-polysiloxanes and fillers to raw mixtures in a kneading cascade with at least two kneading chambers arranged side by side in series, which respectively contains kneading tools driven in same- or opposite directions, located parallel to an axis, and are transversely connected together to the axis of the kneading tools passable openings, where the first kneading chamber exhibits an input opening and the last kneading chamber exhibits a discharge opening, and kneading the raw mixture; and (b) kneading and degassing the crude mixture in a continuously operating double hollows kneader with discharge screw, at 100-250[deg] C. |
