SPONGE-FORMING LIQUID SILICONE-RUBBER COMPOSITION AND SILICONE RUBBER SPONGE MADE THEREFROM |
摘要 |
<p>A sponge-forming liquid silicone-rubber composition comprising: a diorganopolysiloxane (A) comprising a diorganopolysiloxane (A1) that has alkenyl groups on both molecular terminals and does not have any alkenyl groups in molecular side chains; and a diorganopolysiloxane (A2) that has two or more alkenyl groups in molecular side chains; an organohydrogenpolysiloxane (B) that has in one molecule at least two silicon-bonded hydrogen atoms; a mixture (C) composed of water and inorganic thickener; an emulsifier (D); a hydrosilylation-reaction catalyst (E); and a curing retarder (F). The aforementioned sponge-forming liquid silicone-rubber composition provide a silicone-rubber sponge that has a reduced coefficient of shrinkage upon molding, does not bleed out non-cross-linked components, and has a fine, uniform, and continuous porosity.</p> |
