ABSTRACT:
A method for preparing a siloxane foam by mixing an organohydrogensiloxane, a hydroxylated organosiloxane, a platinum catalyst, and an aluminum silicate, and thereafter allowing a foam to form. Preferably, the aluminum silicate comprises about from thirty percent (30%) to about forty percent (40%) by weight of the total composition. The new foams are economical and have improved fire retardancy, physical strength, sealing and wear characteristics, and consistency of composition. The new foams are especially useful as fire retardant insulation in the construction industry, especially as a protective encasement for mechanical and electrical wires, pipes, conduits, and the like.
