                 Abstract: The addition-type liquid silicone rubber was foamed using physical foaming agents, sodium
             bicarbonate as a foaming aid, and hollow glass microspheres, respectively, to obtain foamed silicone rubber.
             This paper deeply investigated the effects of three foaming aids and their different dosages on the foaming
             effect, and conducted characterization and testing of the structure and properties of the successfully
             prepared foamed silicone rubber. The research results showed that the foaming effect of the foamed silicone
             rubber prepared using physical foaming agents was more ideal, and medium-foaming foam materials could
             be prepared; the tensile strength and elongation increased with the increase in the density of the foamed
             silicone rubber; the pressure during molding has a significant impact on the foaming effect, and the foaming
             ratio increased as the pressure decreased.
                 Key words: addition-type liquid silicone rubber; foaming agent; foamed silicone rubber; foaming ratio;
             tensile strength
