Title:
POLYPHENYLENE SULFIDE RESIN COMPOSITION AND MOLDED ARTICLE FORMED FROM SAME
Document Type and Number:
WIPO Patent Application WO/2022/209848
Kind Code:
A1
Abstract:
The present invention addresses the problem of achieving: a polyphenylene sulfide resin composition which has flame retardancy, flexibility and toughness at the same time; and a molded article which is formed from this polyphenylene sulfide resin composition. The purpose of the present invention is to provide a polyphenylene sulfide resin composition which contains (a) a polyphenylene sulfide resin and (b) a silicone polymer compound, wherein: the content of the component (b) relative to 100 parts by weight of the component (a) is 3 to 40 parts by weight; with respect to the morphology (phase structure) of the polyphenylene sulfide resin composition, the polyphenylene sulfide resin composition has a phase separation structure wherein the component (a) forms a continuous phase and the component (b) forms dispersed phases that are dispersed with a number average dispersed particle diameter of 3.0 μm or less; a test piece which is obtained by injection molding the polyphenylene sulfide resin composition at a cylinder temperature of 310°C and a mold temperature of 145°C has a bending modulus of elasticity of 3.0 GPa or less as determined by a bending test that is performed in accordance with ISO 178; and the flame retardancy of a test piece that has a thickness 1.6 mm t or less is V-0 as determined according to UL 94 standard.
