Abstract
Official abstract text for this publication.
The present invention is concerned with expanded beads of thermoplastic polyurethane in which a water-soluble anionic surfactant is attached at 50 mg/m 2 to 1,000 mg/m 2 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.
First claim
Opening claim text (preview).
1 . Expanded beads of thermoplastic polyurethane in which a water-soluble anionic surfactant is attached at 50 mg/m 2 to 1,000 mg/m 2 onto the surfaces of expanded beads of thermoplastic polyurethane having a dispersant attached thereto. 2 . The expanded beads of thermoplastic polyurethane according to claim 1 , wherein the thermoplastic polyurethane that constitutes the expanded beads of thermoplastic polyurethane is an ether-based thermoplastic polyurethane. 3 . The expanded beads of thermoplastic polyurethane according to claim 1 , wherein the anionic surfactant is a polyacrylic acid salt. 4 . A method for producing an expanded thermoplastic polyurethane beads molded article, comprising filling 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, wherein the expanded beads of thermoplastic polyurethane are ones obtained by attaching a water-soluble anionic surfactant in a range of from 50 mg/m 2 to 1,000 mg/m 2 onto the surfaces of expanded beads of thermoplastic polyurethane having a dispersant attached thereto. 5 . The method for producing an expanded thermoplastic polyurethane beads molded article according to claim 4 , wherein the thermoplastic polyurethane that constitutes the expanded beads of thermoplastic polyurethane is an ether-based thermoplastic polyurethane. 6 . An expanded thermoplastic polyurethane beads molded article obtained by the method for producing an expanded thermoplastic polyurethane beads molded article according to claim 4 .
