PROBLEM TO BE SOLVED: To provide propylene resin moldings showing useful rigidity and excellent impact strength as an industrial material for automotive components, appliance components, etc., and a method for manufacturing the propylene resin moldings. SOLUTION: These propylene resin moldings are obtained by a manufacturing method comprising a process to shape a propylene resin containing 5 to 40 mass% polypropylene with 6.0 dl/g or above limiting viscosity, with the help of an injection molding machine etc. and a process to thermally treat the precursor of the moldings at 150 to 170°C. Also the method for manufacturing the propylene resin moldings are provided. COPYRIGHT: (C)2008,JPO&INPIT |
