POLYARYLENE SULFIDE-BASED RESIN COMPOSITION AND INSERT-MOLDED ARTICLE
Document Type and Number:
Japanese Patent JP2021120422
Kind Code:
A
Abstract:
To provide: a polyarylene sulfide-based resin composition having excellent high and low temperature impact resistance, low-warpage, and fluidity; and an insert-molded article using the resin composition.SOLUTION: There is provided a polyarylene sulfide-based resin composition which comprises: a polyarylene sulfide-based resin A; a fibrous inorganic filler B1 having an aspect ratio, which is a ratio of the major axis to the minor axis in a cross section perpendicular to the longitudinal direction, of 3.0 or more; a non-fibrous inorganic filler B2; and olefin-based copolymers C and D each having a predetermined structural unit, wherein the mass ratio B1/B2 of the fibrous inorganic filler B1 to the non-fibrous inorganic filler B2 is more than 1.0, the content of a fibrous inorganic filler B3 having a longitudinal aspect ratio of 2.0 or less is 50 parts by mass or less with respect to 100 parts by mass of the polyarylene sulfide-based resin A, and the contents of the olefin-based copolymers C and D are respectively 3 parts by mass or more and less than 19 parts by mass, and 3 parts by mass or more and 30 parts by mass or less with respect to 100 parts by mass of the polyarylene sulfide-based resin A.SELECTED DRAWING: None
