STYRENE-MODIFIED THERMOPLASTIC POLYURETHANE RESIN BEADS, EXPANDABLE STYENE-MODIFIED THERMOPLASTIC POLYURETHANE RESIN BEADS, STYRENE-MODIFIED THERMOPLASTIC POLYURETHANE RESIN EXPANDED BEADS, AND STYRENE-MODIFIED THERMOPLASTIC POLYURETHANE RESIN EXPANSION MOLDED FORM, AND METHOD FOR PRODUCING THEM

摘要

PROBLEM TO BE SOLVED: To provide a styrene-modified thermoplastic polyurethane resin expansion molded form better in physical properties than conventional polystyrene-based resin expansion molded forms. SOLUTION: 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, wherein the thermoplastic polyurethane resin contains polystyrene-based resin particles 0.5 μm or less in major axis in a dispersed state.
