Procedure
About 2 parts by weight silico-formic acid and about 4 parts by weight hexamethylene diisocyanate are mixed and heated to about 50° C while agitating for about 50 minutes thereby producing a hexamethylene diisocyanate silico-formate polymer. About 3% by weight of an activator mixture containing 25% dimethyl ethanolamine and 10% ammonium stearate in water is added to the mixture, mixed well, and heated to about 50° C thereby producing a semi-rigid hexamethylene diisocyanate-silico-formate foam which has expanded to approximately 6 times its original volume.
