Siloxane compositions comprising 100 parts by weight of polydiorganosiloxane, 10 to 100 parts by weight of reinforcing silica filler, and 0.1 to 5 parts by weight of manganous oxide are elastomeric bases. When further compounded with organic peroxide and optional additives and cured, the finished products exhibit improved heat stability. If flame-retardant additives are used, the finished products exhibit improved flame-retardancy. The manganous oxide is a purified material having a maximum particle size of 15 micrometers. |
