PURPOSE: Provided are a silicone rubber composition for preparing cables and profiles which retains functions of cables and profiles in the event of fire, and a process for preparation thereof. CONSTITUTION: The composition includes at least one peroxidically crosslinking, condensation-crosslinking or addition-crosslinking silicone rubber; at least one metal compound component selected from the group consisting of magnesium oxide, aluminum oxide, tin oxide, calcium oxide, barium oxide, metal oxide precursors thereof, boric acid, zinc borate, and mixtures thereof; at least one platinum complex containing at least one unsaturated group; and hollow beads. The platinum complex is a platinum-vinylsiloxane complex. The platinum-vinylsiloxane complex is a platinum-1,3-divinyl-1,1,3,3-tetramethyldisiloxane complex. The hollow beads are expandable hollow beads.
