摘要： A method of producing elastomeric silicone foams from a two-part system is disclosed. The method mixes the ingredients then allows a froth to form and cure at ambient temperature to an elastomeric silicone foam. The method mixes a vinyl-containing polydiorganosiloxane (1), a hydroxylated polydiorganosiloxane (2), a platinum catalyst (3), an organohydrogensiloxane (4) and a profoamer (5). The profoamer is a resinous, benzene-soluble organosiloxane copolymer consisting essentially of SiO.sub.4/2 units, silicone bonded hydroxyl groups, (CH.sub.3).sub.3 SiO.sub.1/2 units, and fluorine-containing units. An embodiment of the method includes a liquified blowing agent and stores the mixture under superatmospheric pressure, forming a foam by releasing the mixture to atmospheric pressure. Another embodiment includes an alcohol in the mixture to provide a foam of lower density. When lauryl alcohol is used and the alcohol is mixed with (1), (3), and (5) before (2) is admixed, the foam has a Bashore resiliency of less than 20.

摘要： A composition useful in producing an open-cell, elastomeric silicone foam combines a silicone oil-in-water emulsion, which forms an elastomer upon removal of the water, with an aerosol propellant. When the composition is discharged to atmospheric pressure, a froth is formed. Removing water from the froth yields an open-cell foam. The froth is stabilized by surfactants, thickeners, or froth stabilizers selected from fibers or lauryl alcohol.

摘要： Moisture curable, foamable compositions, that do not slump appreciably in the uncured state when applied on a vertical surface, consist essentially of an RTV elastomeric composition, a liquified blowing agent and finely divided silica. The RTV elastomeric composition comprises the product obtained by mixing (1) at least two hydroxyl endblocked polymers selected from diorganosiloxane homopolymers and copolymers, and (2) an effective amount of a moisture reactive crosslinker for the hydroxyl endblocked polymer where from 0 to 80% by weight of said hydroxyl enblocked polymers is a graft copolymer derived from a liquid polydiorganosiloxane and an ethylenically unsaturated organic monomer. When the silica content is less than 10 percent by weight of the composition or the blowing agent concentration exceeds 20 percent by weight of said composition, the composition contains a slump inhibiting amount of said graft copolymer.

摘要： This invention relates to a method of producing silicone elastomeric foam of low density. The method mixes polydiorganosiloxanes having hydroxyl endblocking or vinyl endblocking or mixtures of both along with water to react with silicon hydride in the presence of platinum catalyst to release hydrogen gas to create a froth which cures to a foam. The combination of ingredients allows the manufacture of silicone foam having different combinations of properties than those obtained from previous methods. Embodiments of the invention also make use of specific profoamers and specific alcohols to further modify the properties of the foams produced. The method of this invention yields a low cost, low density, silicone elastomeric foam having physical properties which enable it to be used in cushioning and sealing applications.
