  • Patent number: 11359082
    Abstract: Disclosed are: a polypropylene-based resin composition comprising 100 parts by mass of polypropylene-based resin (A) (provided that, when the polypropylene-based resin includes other resins and/or inorganic filler, the total amount of the polypropylene-based resin and other resins and/or inorganic filler is taken as 100 parts by mass), 0.80 to 5.0 parts by mass of on or more types of aluminum flakes (B) having an average particle size of 5 to 90 ?m, and 0.005 to 0.06 parts by mass of carbon black (C); and a molded article obtained by injection-molding this polypropylene-based resin composition. The polypropylene-based resin composition and the molded article obtained from this are excellent in a flip-flop metallic feeling, a heavy luxury feeling, light resistance and a feeling of luminance.

  • Patent number: 7893120
    Abstract: A pulverized thermoplastic resin product such as a pulverized thermoplastic product containing a black pigment, a mixture of a pulverized thermoplastic product containing a colored pigment and a pulverized thermoplastic product containing a colored pigment, or a pulverized thermoplastic product containing two or more different colored pigments can be converted into colored reclaimed resin particles by a method comprising the steps of mixing the pulverized resin product with a white pigment and a black pigment, melting the resulting mixture, and converting the molten mixture into solid particles. The colored reclaimed resin products can be utilized in various field.

  • Publication number: 20040130053
    Abstract: A thermoplastic resin product having a skin film, such as a bumper of automobile can be used to produce reclaimed resin particles utilizable in various uses, without removing the skin film, by mixing a pulverized thermoplastic resin product containing a small amount of cured resin particles and a black or colored pigment with one or more of a light-shielding pigment such as a white pigment, a black pigment, and a colored pigment, converting the mixture into a molten product, and converting the molten product into solid particles.
