PIPE-SHAPED INTEGRALLY MOLDED ARTICLE AND PRODUCTION METHOD FOR PIPE-SHAPED INTEGRALLY MOLDED ARTICLE

WIPO Patent Application WO/2019/139061

A1

Provided are: a pipe-shaped integrally molded article which is formed by molding a polyphenylene sulfide resin composition, and which has, at one or more portions thereof, at least one selected from sections having different shapes, bent sections, and sections having different diameters, the pipe-shaped integrally molded article being characterized in that the total length L (mm) thereof is 1000 or more, and the ratio (L/D) of an outer diameter D (mm) of the pipe-shaped integrally molded article to the total length L (mm) is 20 or more; and a production method for the pipe-shaped integrally molded article. According to the present invention, it is possible to efficiently provide a pipe-shaped integrally molded article having a desired length and including a three-dimensionally complicated shape, by using a PPS resin composition having excellent heat resistance and chemical resistance.
