  • Patent number: 11286374
    Abstract: The present disclosure relates to a polyarylene sulfide resin composition for an automobile headlamp component, a method for producing the same, and an automobile headlamp component manufactured using the same. The polyarylene sulfide resin composition includes: about 45 wt % to about 75 wt % of a polyarylene sulfide resin containing about 300 ppm or less of chlorine; about 24.5 wt % to about 55 wt % of an inorganic filler; about 0.1 wt % to about 1 wt % of a nucleating agent; about 0.05 wt % to about 1 wt % of metal powder; and about 0.1 wt % to about 2.5 wt % of a composite metal hydroxide.
    Type: Grant

  • Patent number: 9499687
    Abstract: Provided is a polypropylene resin composition. The polypropylene resin composition includes: from about 20 to about 80 parts by weight of a polypropylene resin; from about 1 to about 35 parts by weight of an amine-based kenaf master batch; and from about 1 to about 25 parts by weight of a vinyl-based acetal compatibilizer. Also disclosed is the polypropylene resin composition which is used for vehicle interior and exterior materials, thereby improving physical properties such as low-temperature properties and tensile strength and providing superior resistance against damages.

  • Patent number: 9200151
    Abstract: The present invention provides a polypropylene resin composition including (A) about 60 to 80% by weight of a base resin selected from the group consisting of a high crystalline polypropylene, a propylene-ethylene copolymer, and a mixture thereof; (B) about 2 to 8% by weight of a styrene-ethylene/butene-styrene elastomer; (C) about 6 to 10% by weight of an ethylene-octene elastomer; (D) about 5 to 10% by weight of whisker; (E) about 2 to 8% by weight of talc; (F) about 1 to 3% by weight of a modified polypropylene grafted with maleic anhydride; (G) about 1 to 5% by weight of a vinyl-based acetal compatibilizer; and (H) about 1 to 3% by weight of a slipping agent containing a siloxane-based compound and an amide-based compound, with respect to the total weight of polypropylene. Polypropylene resin compositions according to the present invention can exhibit excellent physical properties such as high stiffness and impact resistance even though formed into a thin film.
