ABSTRACT:
Silicone compositions consisting essentially of 100 parts by weight organopolysiloxane, 20-200 parts by weight finely divided silica filler, 5-100 parts by weight finely divided manganese carbonate, and 5-1,000 ppm platinum alone or in a platinum containing material, based on the weight of the organopolysiloxane. Finished products prepared by molding the compositions exhibit particularly excellent flame-proofing and improved degrees of permanent strain caused by stress. Particularly preferred are silicone compositions with 5-100 parts by weight of finely divided manganese carbonate having a particle size from about 1.mu. to about 50.mu..
