Title:
POLYARYLENE SULFIDE RESIN COMPOSITION, MOLDED ARTICLE, AND METHODS FOR PRODUCING SAID POLYARYLENE SULFIDE RESIN COMPOSITION AND MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2023/218850
Kind Code:
A1
Abstract:
The present invention provides a polyarylene sulfide (PAS) resin molded article that has excellent thermal conductivity and mechanical characteristics and suppresses wear of materials in a sliding environment, a PAS resin composition that can provide said molded article, and methods for producing the resin composition and the molded article. More specifically, a PAS resin composition for a sliding member, obtained by blending a PAS resin with graphite, the PAS resin composition being characterized in that the melt viscosity (V6) of the PAS resin is 90-350 Pa∙s inclusive, the graphite is scaly, the amount of graphite blended is 5-50 mass parts per 100 mass parts of the resin composition, and the MD/TD ratio of the linear expansion coefficients of the resin composition is 0.5 or more; a molded article; and methods for producing the resin composition and the molded article.
