Title:
INORGANIC REINFORCED THERMOPLASTIC POLYESTER RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/059125
Kind Code:
A1
Abstract:
Provided is an inorganic reinforced thermoplastic polyester resin composition capable of producing a long and thin-walled molded article which has high strength and high rigidity, maintains a good surface appearance, and has a low occurrence of burrs, the inorganic reinforced thermoplastic polyester resin composition containing (A) 16-30 mass% of a polybutylene terephthalate resin, (B) 10-25 mass% of at least one polyester resin other than the polybutylene terephthalate resin, (C) 50-70 mass% of an inorganic reinforcing material, (D) 0.1-3 mass% of a glycidyl group-containing styrene-based copolymer, and (E) 0.5-2 mass% of an ethylene-glycidyl(meth)acrylate copolymer, wherein the mass ratio of component (A) to component (B), and the mass ratio of component (B) to component (E) are within specific ranges.
