Title: POLYESTER ELASTOMER RESIN COMPOSITION FOR BLOW MOLDING
Abstract:
The present invention is a polyester elastomer resin composition for blow molding, which contains a thermoplastic polyester elastomer (A), a difunctional or higher epoxy compound (B), an alkali metal salt (C) of an organic carboxylic acid having 3-40 carbon atoms, an inorganic crystal nucleating agent (D) and a urea compound scavenger (E) having an amine value of 50 eq/t or more. The polyester elastomer resin composition contains 0.1-5 parts by mass of the component (B), 0-3 parts by mass of the component (D) and 0.1-5 parts by mass of the component (E) relative to 100 parts by mass of the component (A), and contains the component (C) at a quantity of 50-2000 ppm by mass in terms of alkali metal in the polyester elastomer resin composition. The polyester elastomer resin composition exhibits excellent blow molding properties, can suppress the occurrence of sinks in a thick part of a molded article and moreover, exhibits excellent heat aging resistance in a grease-attached state.
