Nonflammable foam body and method of manufacturing the foam body |
摘要 |
A resin composition containing thermoplastic resin and a flame retardant is sufficiently kneaded and molded and carbon dioxide in a supercritical state is caused to permeate into it. Subsequently, the resin composition is degassed by cooling and/or pressure reduction. As a result of degassing, a resin foam body 1 having a fine and uniform micro-cellular foam structure is obtained. The resin foam body 1 has a cyclic structure in which a resin phase 2 and a pore phase 3 are continuous and intertwined. The obtained resin foam body 1 can suitably find applications such as home OA parts, electric and electronic parts and automobile parts that are required to be highly strong, lightweight and nonflammable.
