HIGH PERFORMANCE THERMOPLASTIC ELASTOMER COMPOSITION

摘要

The present invention provides a thermoplastic elastomer composition comprising: 100 parts by weight of component (A), 10 to 100 parts by weight of component (B), 50 to 200 parts by weight of component (C), and 5 to 30 parts by weight of component (D). Component (A) is a propylene polymer having a melting point of 155 °C or more. Component (B) is a crystalline propylene-ethylene copolymer. Component (C) is an ethylene-a-olefin rubber having Mooney Viscosity of 30 to 100(ML1+4, 125 °C). Component (D) is a hydrogenated product of block copolymer comprising blocks of aromatic vinyl compound units and blocks of conjugated diene compound units.
