INJECTION-MOLDED OBJECT

摘要

An injection molding which is biodegradable and excellent in flame retardancy and mechanical strength. The injection molding comprises 100 parts by mass of a lactic acid resin and 5 to 40 parts by mass of a metal hydroxide, wherein the metal hydroxide has been surface-treated and the amount of Na2O (w-Na2O) present on the surface of the metal hydroxide particles is 0.1 mass % or smaller. The injection molding preferably further contains an aliphatic polyester or aromatic aliphatic polyester other than lactic acid resins in an amount of 20 to 80 parts by mass per 100 parts by mass of the lactic acid resin.
