  • Polyphenylene sulfide resin composition, production method thereof and molded product thereof
    Patent number: 9068078
    Abstract: There is provided a polyphenylene sulfide (PPS) resin composition, comprising: 5 to 50 parts by weight of a polyamide resin (b) and 50 to 250 parts by weight of a metal hydroxide (c) relative to 100 parts by weight of a polyphenylene sulfide resin (a), wherein the metal hydroxide is dispersed in the composition at an average secondary particle diameter equal to or less than 5 ?m. The PPS resin composition may provide excellent tracking resistance without significantly damaging various intrinsic properties of a PPS resin, such as excellent mechanical strength and low gas generation.
