Technology for Obtaining Foamed Rubber and Latest Technological Trends Takashi Hakuta MITSUI CHEMICALS,INC.,Chiba,Japan Nippon Gomu Kyokaishi,(2003),76(6), 212-218 General Review in Japanese. Abstract Foamed rubber is now widely used in a variety of technological applications.  First,the text explains the general outline of technology for obtaining foamed rubber such as the choice of blowing agents, the balance a cure crosslinking reaction and a blowing agent decomposition reactions, and the mechanism of foamed rubber.  Second, the text explains manufacture technology of weather-strip sponge which is the typical sponge product of EPDM.  Finally,the text introduces the latest technology for contributing to the cost-reduction of foamed rubber, the safety sanitation and the performance improvement such as the high-cure crosslinking reaction-EPDM, the EPDM alloy and EPDM by hydrosilylation. Keywords: Foamed rubber, Blowing agent , Sponge, EPDM
