The invention relates to a vulcanizable rubber composition, which comprises a) one or more rubbers that can be cross-linked by means of amine, b) one or more light-colored fillers, and c) one or more polyorganosiloxanes having at least two NH 2 groups per molecule. The total amount of organosilane is restricted in the rubber compositions. After vulcanization, the rubber compositions exhibit good compression set. |
