Document Type and Number:
WIPO Patent Application WO/2022/215395
Kind Code:
A1
Abstract:
Provided are: a polyarylene sulfide (PAS) resin molded article that includes PAS resin, a fibrous filler, and a non-fibrous filler, suppresses swelling caused by fuel, and has excellent dimensional stability and mechanical properties even after being immersed in fuel; a PAS resin composition that can provide said PAS resin molded article; and production methods for these. More specifically provided are: a PAS resin composition for fuel system components, which contains a PAS resin (A), glass fibers (B), and a non-fibrous filler (C) as essential components, the PAS resin composition being characterized in that the PAS resin (A) is a crosslinked PAS resin, has an isothermal crystallization time of 0.7–3.7 minutes, and the glass fibers (B) are contained in an amount of 50 to 150 parts by mass and the non-fibrous filler (C) in an amount of 50 to 150 parts by mass, relative to 100 parts by mass of the PAS resin (A); a molded article; and methods respectively for producing the PAS resin composition and the molded article.
