Abstract
A method of reducing the density of a silicone foam is provided comprising mixing with a foamable silicone composition having a base polydiorganosiloxane, an effective amount of a resinous copolymer selected from the group consisting of resinous copolymers of R.sub.3 SiO.sub.0.5 units and SiO.sub.2 units, and ratio of R.sub.3 SiO.sub.0.5 units ranging from 0.25 to 0.8:1, and resinous copolymers formed from R.sub.3 SiO.sub.0.5 units, R.sub.2.sup.1 SiO units and SiO.sub.2 units, the ratio of R.sub.3 SiO.sub.0.5 to SiO.sub.2 units ranging from 0.25 to 0.8:1 and the ratio of R.sub.2.sup.1 SiO to SiO.sub.2 units ranging from 0 to 0.1:1, and thereafter simultaneously foaming and curing the mixture.
