Abstract

The process of obtaining siloxane elastomeric foams according to the parent Specification is modified by using an organopolysiloxane having a viscosity of at least 50 but less than 1,000 c.s. at 25 DEG C.; and the hydroxylated compound is limited to silanols, low molecular weight hydroxylated siloxanes, water, carboxylic acids and alcohols containing less than 12C atoms. Additives are as in the Provisional Specification.ALSO:The process of obtaining siloxane elastomeric foams according to the parent Specification is modified by using an organopolysiloxane having a viscosity of at least 50 but less than 1000 c.s. at 25 DEG C.; and the hydroxylated compound is limited to silanols, low molecular weight hydroxylated siloxanes, water, carboxylic acids and alcohols containing less than 12 C. atoms.
