In this paper, foaming process used supercritical carbon dioxide as a physical blowing agent and the characteristics of the foamed silicone rubber, which is vulcanized rubber, were investigated. First, the degree of vulcanization of silicone rubber was evaluated by the plasticity. And the relationship between plasticity and foaming conditions was investigated using samples changed variously degrees of vulcanization. Foaming process of vulcanized rubber was designed based on plasticity of rubber and discussed. And besides, the characteristics of foamed rubber were also measured. As results, foamed rubbers having fine cell size were produced using carbon dioxide as a physical blowing agent
