HOLLOW MOLDED ARTICLE

PROBLEM TO BE SOLVED: To provide a twin composite molded article in which bonding strength at the thermally fused section of a thermoplastic resin sheet is large, an unfavorable shaping and wrinkles are not generated, excellent appearance is presented, and in addition, a deflection temperature at loading is high, and which is suitable for in-line coating. SOLUTION: The thermoplastic resin hollow molded article is shaped in such a manner that two pieces of sheets are used, and closely joined to a die surface. In the thermoplastic resin hollow molded article, the thermoplastic resin is a polyphenylene ether resin composition (A-2). (1) The deflection temperatures at loading as the two pieces of the sheet materials are 120°C or higher. (2) When a temperature at which storage elasticity E' becomes 3×108Pa is taken as Th, and a temperature at which the storage elasticity E' becomes 1×107Pa is taken as Ts, (Ts-Th) is 20°C or lower. Also, (3) when hot plate weldable temperatures of the two pieces of the sheets are taken as Tw, (Tw-Ts) is 15°C or lower for the hollow molded article. COPYRIGHT: (C)2011,JPO&INPIT
