Publication number: 20210246304Abstract: A thermoplastic resin composition including a thermoplastic resin component and a glass filler (C), the thermoplastic resin component including a polycarbonate resin (A) having a viscosity-average molecular weight of 13,000 to 22,000 and a polyester resin (B) including a terephthalic acid residue, a 1,4-cyclohexanedimethanol residue, and a 2,2,4,4-tetramethyl-1,3-cyclobutanediol residue. The amounts of the polycarbonate resin (A) and the polyester resin (B) are 25 to 65 parts by mass and 75 to 35 parts by mass, respectively, relative to 100 parts by mass of the total amount of the polycarbonate resin (A) and the polyester resin (B). The amount of the glass filler (C) is 10 to 45 parts by mass relative to 100 parts by mass of the thermoplastic resin component. A molded article is produced by performing injection molding of the thermoplastic resin composition with a heat-insulation mold or heat-and-cool molding of the thermoplastic resin composition.Type: ApplicationFiled: April 25, 2019Publication date: August 12, 2021Applicant: Mitsubishi Engineering-Plastics CorporationInventor: Kosei HINO
