  • Thermoplastic resin composition and article produced therefrom
    Patent number: 11091624
    Abstract: A thermoplastic resin composition of the present invention comprises: a thermoplastic resin comprising an acrylate rubber-modified vinyl graft copolymer and an aromatic vinyl copolymer resin; a crosslinked aromatic vinyl copolymer resin; and zinc oxide having an average particle size of about 0.3 to 3 ?m and a BET specific surface area of about 1 to 10 m2/g. The thermoplastic resin composition and the article formed therefrom are excellent in low-glossiness, weather resistance, antibacterial properties, etc.
    Type: Grant
    Filed: December 21, 2017
    Date of Patent: August 17, 2021
    Assignee: Lotte Advanced Materials Co., Ltd.
    Inventors: Min Kyoung Ham, Dong Hyun Park, Eun Joo Lee, Young Chul Kwon, Yun Jeong Yang, Hyun Ji Oh
  • Thermoplastic resin composition and molded article using the same
    Patent number: 10717858
    Abstract: A thermoplastic resin composition and a molded article produced using the same. The thermoplastic resin composition includes: a styrene-based copolymer resin; a rubber-modified acrylic graft copolymer; a silicone compound-containing branched copolymer; glass fibers; and metal particles, wherein a weight ratio of the branched copolymer to the glass fibers ranges from about 1:1 to about 6:1.

  • Thermoplastic resin composition and molded article using the same
    Patent number: 9340668
    Abstract: A thermoplastic resin composition and a molded article including the same are disclosed. The thermoplastic resin composition includes: (A) a base resin including (a1) a styrene copolymer and (a2) a rubber-modified vinyl graft copolymer; and (B) surface-treated metal particles, wherein the surface-treated metal particles include: a metal core; a first coating layer formed on the metal core; and a second coating layer formed on the first coating layer. The thermoplastic resin composition can exhibit significantly improved glossiness and appearance by preventing flow marks and weld lines that can occur upon injection molding, while exhibiting a luxurious metallic texture even without painting.
