THERMOPLASTIC ELASTOMER COMPOSITION, POWDER OF THE SAME COMPOSITION AND MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To obtain a thermoplastic elastomer composition capable of providing a molded product excellent in appearance and tensile characteristics even at a relatively low molding temperature such as about 210 deg.C in the thermoplastic elastomer composition consisting essentially of a polyolefin-based resin and a hydrogenated vinyl-aromatic compound-conjugated diene compound copolymer, a powder of the composition and the molded product prepared by using the powder. SOLUTION: This thermoplastic elastomer composition comprises 100 pts.wt. of a polyolefin-based resin and 10-250 pts.wt. of a hydrogenated vinyl-aromatic compound-conjugated diene compound copolymer and has <=3×104 P complex dynamic viscosityη* (0.1) at 210 deg.C. The powder of the thermoplastic elastomer composition comprises the thermoplastic elastomer composition. The molded product uses the powder of the thermoplastic elastomer composition.
