POLYARYLENE SULFIDE RESIN COMPOSITION, MOLDED ARTICLE, AND INSERT-MOLDED ARTICLE

摘要

The present invention is a polyarylene sulfide resin composition used to mold a molded article that can come into contact with fluids including water, wherein: the composition contains 2.0–9.0 parts by mass of a prescribed olefin copolymer, 5–40 parts by mass glass fibers, and 0.1–0.7 parts by mass of a silane coupling agent per 100 parts by mass of a polyarylene sulfide resin having a melt viscosity of 100–250 Pa·s; the content ratio of structural units derived from α,β-unsaturated acid glycidyl esters to the olefin copolymer is 1.0–8.0 mass%; and the composition has a 20 mm-width and 1 mm-thickness flow length of 110–300 mm at a prescribed cylinder temperature, injection pressure, dwell pressure, and mold temperature.
