  • Blowing agent compositions and compositions curable to give elastomeric silicone foams
    Patent number: 5332762
    Abstract: Blowing agent compositions (a) comprising aqueous emulsions containing organopolysiloxanes (1), emulsifiers (2), water (3) and thickeners (4) which may be used in the preparation of elastomeric silicone foams.The blowing agent compositions are used in curable compositions to form elastomeric silicone foams which comprise the blowing agent compositions (a), diorganopolysiloxanes (b), crosslinking agents (c) and, if appropriate, crosslinking catalysts (d) and optionally fillers (e). Elastomeric silicone foams are prepared by mixing the blowing agent compositions (a), with curable organopolysiloxane compositions containing diorganopolysiloxanes (b), crosslinking agents (c) and, if appropriate, crosslinking catalysts (d) and optionally fillers (e) and also optionally additional substances and then the resultant mixture is cured at temperatures in the range of from 100.degree. to 250.degree. C. with simultaneous foaming to form the elastomeric silicone foams.
