Title:
POLYARYLENE SULFIDE RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2024/048558
Kind Code:
A1
Abstract:
Provided is a polyarylene sulfide resin composition that can give molded articles that exhibit an excellent bending strength and an excellent impact strength. The polyarylene sulfide resin composition comprises a polyarylene sulfide resin (A); a fibrous inorganic filler (B) that has an aspect ratio of at least 3.0, wherein this aspect ratio is the ratio between the major axis and minor axis of a cross section perpendicular to the longitudinal direction; and an alkoxysilane compound (C). The cooling crystallization temperature (Tc) of the polyarylene sulfide resin (A) is at least 215°C; the content of the fibrous inorganic filler (B) that has an aspect ratio of at least 3.0, wherein this aspect ratio is the ratio between the major axis and minor axis of a cross section perpendicular to the longitudinal direction, is 55 to 180 parts by mass per 100 parts by mass of the polyarylene sulfide resin (A); and the content of the alkoxysilane compound (C) is 0.5 to 10 parts by mass per 100 parts by mass of the polyarylene sulfide resin (A).
