| Abstract: | s A foamable silicone rubber compound was prepared from the rubber compound filled with fumed silica and precipitated silica, taking AC as foaming agent, compounding with proper auxiliary foaming agent, and using DBPMH as vulcanizing agent. Silicone sponge rubbers with different sectional forms were then prepared from the foamable silicone rubber compoud by means of extrusion molding and vulcanizing, the tensile strength and elongation at break of the silicone sponge rubber were 0.52 MPa and 160% respectively. |
