摘要:
The present invention is concerned with expanded beads of thermoplastic polyurethane in which a water-soluble anionic surfactant is attached at 50 mg/m2 to 1,000 mg/m2 onto the surfaces of expanded beads of thermoplastic polyurethane having a dispersant attached thereto; and a method for producing an expanded beads molded article, including filling the expanded beads of thermoplastic polyurethane in a mold for molding and heating with a water vapor to mutually fuse the expanded beads with each other. The present invention provides expanded beads from which an expanded TPU beads molded article having excellent tensile strength and a method for producing an expanded TPU beads molded article.
