Base compositions for addition-crosslinking silicone compositions are continuously produced by, in a first stage, homogeneously mixing and kneading organopolysiloxanes and flowable prehydrophobized oxidic reinforcing fillers in a continuous kneading machine with kneading chambers arranged alongside one another. In a second, downstream, stage of the process, the compositions produced in the first stage are subjected to aftertreatment in a mixing apparatus in which the compositions have been subjected to a mixing procedure with introduction of shear force.

Continuous process for the production of base compositions for improved-stability silicone compositions

Addition-crosslinkable silicone compositions contain

Addition-crosslinkable silicone compositions with low coefficients of friction

Addition curable elastomer compositions whose cured products exhibit high elongation at break and high tear propagation resistance are prepared from specific molecular weight ranges of alkenyl-terminal, alkenyl-pendant, and substantially non-functional organopolysiloxanes.

Addition-crosslinkable silicone compositions comprising high-viscosity polydiorganosiloxanes

Storage-stable silicone compositions

Silicone compositions having improved heat stability
