PROBLEM TO BE SOLVED: To provide a foam molding unlikely to contract on a molding occasion and accompanied by scarce dimensional deformations without exerting an inner pressure.SOLUTION: The problem-solving thermoplastic polyurethane resin foam particles include a thermoplastic polyurethane resin as a matrix resin, whereas the matrix resin includes a high-compressive-permanent-set thermoplastic polyurethane resin having a compressive permanent set of at least 40% as it is measured in compliance with JIS K 6262. |
