POYETHERESTER THERMOPLASTIC ELASTOMER RESIN COMPOSITION

摘要

A poyetherester thermoplastic elastomer resin composition is provided to ensure high extrusion and hollow moldability by controlling flowability, to satisfy flexibility and mechanical property and to exhibit excellent durability. A poyetherester thermoplastic elastomer resin composition comprises (a) a low-hardness poyetherester block copolymer 10-80 parts by weight with Shore hardness 28~50 D; (b) a high-hardness poyetherester block copolymer 10-80 parts by weight with Shore hardness 51~81 D; (c) polybutylene terephthalate 5-12 parts by weight; and (d) a polyolefin copolymers 6-15 parts by weight containing an epoxy functional group.
