Abstract: This disclosure relates to continuous methods of making foamed silicone elastomers and the compositions used for forming the foamed silicone elastomers in said methods. The compositions utilised 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 liquid blowing agent. Foamed silicone elastomers are prepared from such compositions.
