摘要： A melamine molded foam is produced by heat-compressing a melamine foam to a thickness of {fraction (1/1.2)} to {fraction (1/12)} to cause plastic deformation and temporarily fixing the shape; the heat-compression is performed under the conditions of from 210 to 350° C. for 3 minutes or longer; the heat-compression is preferably performed at a temperature within the range of lower than the decomposition temperature of the melamine monomer by 140° C. or less; in some of such molded foams, the shape recovery in the direction of thickness with the lapse of time is observed depending upon the heat-compression conditions; and the dimensional recovery ratio is 40% or less when allowed to stand at 23° C. for 200 hours.
