INORGANIC FILLER-REINFORCED POLYBUTYLENE TEREPHTHALATE RESIN COMPOSITION

PROBLEM TO BE SOLVED: To provide an inorganic filler-reinforced polybutylene terephthalate resin composition having excellent injection moldability and exhibiting excellent mold releasability in a mold with a complicated shape.SOLUTION: The inorganic filler-reinforced polybutylene terephthalate resin composition is a polybutylene terephthalate resin composition obtained by using a polybutylene terephthalate resin (A) with a water content of 0-0.20 wt.% and a polylactic acid resin (B) with a water content of 0-0.20 wt.%. The polybutylene terephthalate resin composition is prepared by adding and mixing 100 pts.wt. of the polybutylene terephthalate resin (A), 5-100 pts.wt. of the polylactic acid resin, 0.001-5 pts.wt. of boron nitride (C), 0.1-10 pts.wt. of at least one compound (D) selected from fatty oil ester-based wax and polyolefin-based wax, and 3-200 pts.wt. of a glass-based inorganic filler (E). A crystallization peak temperature of the polybutylene terephthalate resin (A) in the resin composition is 200-210°C in the differential scanning calorimetry in conformity with the JIS K7121.
