    Abstract: The invention relates to novel organopolysiloxane compositions which can be crosslinked by means of a condensation reaction. The compositions can be produced using (1) organopolysiloxanes containing condensable end groups, (2) at least three organosilicon compounds which have acyloxy groups (-OCOR) bonded directly to silicon, (3) condensation catalysts, (4) anhydrite, and (5) silicic acids in quantities of at least 1 and maximally 15 parts by weight, preferably maximally 10 parts by weight, for every 100 parts by weight of organopolysiloxane (1) with the proviso that (6) the additional use of kaolin is excluded and (7) additional fillers in quantities of maximally 25 parts by weight, preferably maximally 15 parts by weight, preferably maximally 5 parts by weight, in each case based on 100 parts by weight of organopolysiloxane (1), are additionally used, and (8) optionally additional materials which are normally additionally used in compositions that can be crosslinked by means of a condensation reaction and which differ from the components (1) to (7).
