Abstract
A composition which is useful for producing profiles and cable insulation which retain their function in the event of fire, comprise peroxidically crosslinking or condensation-crosslinking silicone rubber, metal oxides selected from magnesium oxide, aluminum oxide, tin oxide, calcium oxide and barium oxide and metal compounds of this class which produce oxides on heating, boric acid, zinc borate, and a platinum complex having at least one unsaturated group.
Claims16
A composition comprising a peroxidically crosslinking or a condensation-crosslinking silicone rubber;
- one or more metal oxides or metal oxide precursors selected from the group consisting of aluminum oxide, tin oxide, and compounds of magnesium, aluminum, tin, calcium, and barium which produce oxides on heating, boric acid, and zinc borate;
- and at least one platinum complex containing at least one unsaturated hydrocarbon group, said composition free of hydrophobic metal nitrides and carbides, and being a composition which produces a ceramic material at temperatures of 650° C. or more.
