Method and apparatus for the preparation of silicone elastomer foams

摘要: In accordance with the present method for preparing an elastomeric silicone foam, inert gas is injected under superatmospheric pressure during or after merging of a silanol-containing organopolysiloxane that liquid at room temperature organohydrogenpolysiloxane temperature, and hydrosilation catalyst, step followed by mechanical mixing in enclosed chamber, which time mixture ejected into atmosphere. Completion cure simultaneous evolution hydrogen occur atmospheric reactive ingredients all homogeneously microdispersed/mixed state. The stabilizes cells formed makes possible development large quantity uniform size distribution, resulting high-expansion ratio foam.
