Title:
POLYPHENYLENE SULFIDE RESIN COMPOSITION AND MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2020/196273
Kind Code:
A1
Abstract:
[Problem] To provide a polyphenylene sulfide resin composition and a molded article thereof having excellent mechanical properties and dimensional stability, and particularly having significantly inhibited anisotropy and inhibited expansion during a moist heat treatment. [Solution] This polyphenylene sulfide resin composition is a mixture of (A) 100 parts by weight of a polyphenylene sulfide resin, (B) 100-250 parts by weight of atypical cross-section glass fibers, and (C) 25-150 parts by weight of a non-fiber inorganic filler satisfying (C-a) and (C-b), wherein the ratio X/Y of the mass X of the atypical cross-section glass fibers (B) and the mass Y of the non-fiber inorganic filler (C) is more than 1 but less than 7. (C-a) A Mohs hardness of more than 2 but less than 4. (C-b) A melting point or a softening point that is 380°C or higher.
