摘要： A resin foamed product is formed of a resin, and closed cells dispersed in the resin. The resin with the closed cells therein has a shape-recoverable property at an ambient temperature, a closed cell rate higher than 30% and a compression permanent set lower than 10%. Thus, when contraction takes place in the resin with the closed cells, after a predetermined time has passed without providing an outer stimulation to the resin, a shape of the resin foamed product formed of the resin with the closed cells is automatically recovered at least in one direction without equally expanding in all directions.
