Summary:A process for manufacturing foamed silicone compositions by foaming a cross-linkable composition which comprises: (a) 100 parts by weight of a vinyl-containing polysiloxane containing 0.0002 to 3% by weight of vinyl groups and a viscosity of from 0.1 to 1,000 Pascal-seconds at 25 DEG C., (b) up to 10 parts by weight of a silanol-containing silicon compound with a viscosity from 0.01 to 10 Pascal-seconds at 25 DEG C., (c) up to 200 parts by weight of filler, (d) 1 to 50 parts by weight of a polysiloxane with a viscosity of 0.005 to 0.1 Pascal-seconds at 25 DEG C., and (e) a platinum catalyst, is characterized by foaming the cross-linkable composition with a substance containing hydroxyl groups at temperatures of 50 DEG to 150 DEG C.
