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 μm. 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.

A polyphenylene sulfide 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 μm;
- wherein the polyphenylene sulfide resin composition is prepared by melt kneading the composition at a peripheral rate of 15 to 50 m/minute with a twin screw extruder having a screw arrangement including two or more kneading sections.
