  • Patent number: 11332617
    Abstract: A polyarylene sulfide resin composition contains a polyarylene sulfide resin, a transition metal particle, a fibrous inorganic filler, and an inorganic nucleating agent, and a molded article made from the resin composition. The resin composition has excellent mechanical, corrosion, and haze properties, and heat resistance. The resin composition prevents corrosion of a mold and deterioration in the durability of a manufactured product upon injection by effectively removing halogen-based impurities, and also has excellent mechanical, corrosion, and haze properties, and heat resistance. A molded article manufactured from the resin composition satisfies the standards required for components of a vehicle and an electric/electronic device.
