摘要

P To provide a styrene-modified thermoplastic polyurethane resin expansion molded form better in physical properties than conventional polystyrene-based resin expansion molded forms. PSOLUTION: Styrene-modified thermoplastic polyurethane resin beads are provided, comprising 100 pts.mass of a thermoplastic polyurethane resin and 20 pts.mass or more but less than 300 pts.mass of a polystyrene-based resin and wherein the thermoplastic polyurethane resin contains polystyrene-based resin particles 0.5 m or less in major axis in a dispersed state.
