Title:
POLYBUTYLENE TEREPHTHALATE RESIN COMPOSITION AND MOLDING
Document Type and Number:
Japanese Patent JP3929889
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To obtain a polybutylene terephthalate resin composition with excellent moldability and mold releasability, which gives a molding exhibiting very good appearance and paintability in addition to high rigidity.
SOLUTION: The polybutylene terephthalate resin composition is obtained by formulating 40-150 pts.wt. of mixed fillers ((C) + (D)) comprising (C) a glass fiber and (D) one or more fillers selected from (D-1) an acicular filler having 40-200μm average fiber length and (D-2) a granular or platy filler having 5-60μm particle size, and (E) 0.1-5 pts.wt. of an ester compound comprising a ≥26C aliphatic carboxylic acid as a main constituent to 100 pts.wt. of a resin component comprising (A) 95-55 wt.% of a modified polybutylene terephthalate resin containing 5-30 mol% isophthalic acid unit and having 0.60-0.80 intrinsic viscosity (IV) and (B) 5-45 wt.% of a polycarbonate resin.
