THERMOPLASTIC POLYETHERESTER ELASTOMER RESIN COMPOSITION

摘要

PURPOSE: A thermoplastic polyether ester elastomer resin composition is provided to ensure excellent mechanical properties such as durability, molding processability and surface properties, to secure high flexibility and flexural properties. CONSTITUTION: A thermoplastic polyether ester elastomer resin composition comprises: 25-80 weight% of a low hardness polyester ether block copolymer having surface hardness of shore 28D-50D; 10-70 weight% of a high hardness polyester ether block copolymer having surface hardness of shore 51D-81D; 0.01-5 weight% of a porous silica compound; and 0.1-5 weight% of a stabilizer. The polyether ester block copolymer comprises the hard segment of chemical formula 1 and the soft segment of chemical formula 2.
