Abstract
This disclosure relates to continuous methods of making foamed silicone elastomers. This disclosure also relates to compositions used for forming foamed silicone elastomers. The compositions comprise: (i) an organopolysiloxane having at least two silicon-bonded unsaturated groups per molecule; (ii) an organohydrogensiloxane having at least two silicon-bonded hydrogen atoms per molecule; (iii) a hydrosilylation catalyst; and (iv) a physical blowing agent. Foamed silicone elastomers can be prepared from such compositions, using, for example, the methods disclosed herein.
