Cured silicone rubber powder containing large amounts of particulate material formed by dispersing a liquid silicone rubber composition curable by a platinum-catalyzed hydrosilation reaction into water. The presence of a low molecular weight, volatile polydiorganosiloxane makes it possible to incorporate at least 100 parts by weight of particulate material per 100 parts of curable polydiorganosiloxane into the composition. The volatile polydiorganosiloxane is removed from the cured powder. Finely divided magnetic metals, electrically conductive materials and reinforcing silica powders can be incorporated using the present method.
