The invention relates to rubber compositions that are provided with polyorganosiloxanes as plasticizers. The rubber compositions can be vulcanized by means of a cross-linking resin and they are particularly suitable for use as curing bladders in the production of tires. The invention further relates to the use of polyorganosiloxanes as corresponding plasticizers.
