Title:
THERMOPLASTIC POLYESTER RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/179668
Kind Code:
A1
Abstract:
The present invention is a polyester resin composition containing 18-35 parts by mass of a polybutylene terephthalate resin (A), 10-25 parts by mass of a polyethylene terephthalate resin (B), 10-20 parts by mass of a thermoplastic polyester elastomer (C), 0.5-5 parts by mass of an epoxy group-containing ethylene copolymer (D), 12-20 parts by mass of a spherical and/or amorphous inorganic filler (E), 10-35 parts by mass of a glass-fiber impact strength modifier (F), 0-10 parts by mass of a polycarbonate resin (G) and 0-2 parts by mass of a transesterification inhibitor (H). The polyester resin composition exhibits superior heat resistance and ameliorates the formation of sink marks on a molded body while also imparting toughness thereto.
