  • THERMOPLASTIC ELASTOMER COMPOSITION AND THERMOPLASTIC ELASTOMER MOLDED BODY
    Publication number: 20220315748
    Abstract: A thermoplastic elastomer composition: 41 to 70 parts by mass of component (A), 0 to 54 parts by mass of component (B), and 5 to 59 parts by mass of component (C) ((A), (B), and (C) being 100 parts by mass), with dynamic heat treatment with a cross-linking agent. Component (A): a propylene block copolymer having a melt flow rate measured in accordance with ISO1133. Component (B): an ethylene/?-olefin/non-conjugated polyene copolymer including a structural unit derived from ethylene, a structural unit derived from an ?-olefin having 3 to 20 carbon atoms, and a structural unit derived from a non-conjugated polyene. Component (C): an ethylene/?-olefin copolymer including a structural unit derived from ethylene and a structural unit derived from an ?-olefin having 4 to 20 carbon atoms and having a melt flow rate measured in accordance with ISO 1133.
