  • Long fiber-reinforced polyarylene sulfide resin molded article and method for producing the same
    Patent number: 10737427
    Abstract: To provide a polyarylene sulfide (PAS) resin composition and a PAS resin molded article that are excellent in mechanical strengths such as impact resistance while maintaining excellent heat resistance of the PAS resin, and methods for producing the PAS resin composition and the PAS resin molded article. Specifically, provided are a method for producing a long fiber-reinforced PAS resin molded article, the method including obtaining a long fiber-reinforced PAS resin composition containing a PAS resin and a fiber reinforcing material having a fiber length of more than 5 mm, subsequently subjecting the resin composition and a PAS resin to dry blending, and subsequently subjecting the dry-blended substance to melting and subsequently to melt-molding; the long fiber-reinforced PAS resin composition; and a method for producing the long fiber-reinforced PAS resin composition.

  • RESIN COMPOSITION FOR BLOW HOLLOW MOLDED ARTICLES, BLOW HOLLOW MOLDED ARTICLE AND METHOD FOR PRODUCING SAME
    Publication number: 20160319109
    Abstract: Provided are a blow-molded hollow article a method for producing the blow-molded hollow article, a resin composition for blow-molded hollow articles for exclusively providing the blow-molded hollow article, and a method for producing the resin composition. More specifically, provided are a method for producing a blow-molded hollow article containing a polyarylene sulfide resin and a fiber reinforcing material having a fiber length of 5 mm or more, including heating a long fiber-reinforced polyarylene sulfide resin composition containing the polyarylene sulfide resin and the fiber reinforcing material having a fiber length of 5 mm or more at a temperature not lower than a melting point of the resin so as to melt the resin, and subjecting the composition to blow hollow molding, a blow-molded hollow article, a resin composition for blow-molded hollow articles, and a method for producing the resin composition.
