Beschreibung
Zusammenfassung:	Silicone foam compositions for forming foamed silicone elastomers are described herein, together with the respective foamed silicone elastomers formed therefrom and to methods of making such compositions and foamed silicone elastomers. The silicone rubber foam composition comprising: (a) one or more organopolysiloxane polymers having an average of at least two epoxide groups per molecule; (b) a Lewis acid catalyst, (c) one or more surfactants and optionally (d) a physical blowing agent. The foamed silicone elastomers are prepared by either mechanically foaming components (a), (b) and (c); or by introducing a physical blowing agent (d); and causing foaming by physical blowing.
