  • Patent number: 8779037
    Abstract: A polycarbonate resin composition is provided. The composition comprises (A) 50 to 90% by weight of a polycarbonate resin, (B) 5 to 30% by weight of a polymethyl methacrylate resin, (C) 5 to 20% by weight of a phosphate compound, (D) 0.01 to 2% by weight of a metal sulfonate as an organic salt, and (E) 0.05 to 2% by weight of a fluorinated olefin. The composition is highly flame retardant and scratch resistant.

  • Patent number: 8398904
    Abstract: The present invention relates to a microcellular foam of a thermoplastic resin and a method for preparing the same, and more particularly to a microcellular foam comprising a skin layer having a porosity of below 5% and a core layer having a porosity of at least 5%, wherein the thickness of the skin layer accounts for 5 to 50% of the entire foam, and a method for preparing the same. The microcellular foam of the present invention is advantageous in that it has a thicker skin layer and smaller and uniform micropores in the core layer, compared with conventional microcellular foams, while having mechanical properties comparable to those of conventional non-foamed sheets.

  • Patent number: 8378024
    Abstract: The present invention relates to a low surface gloss styrene resin composition. The composition of the present invention is composed of (A) 80-99.9 weight % of the basic resin comprising rubber-modified styrene resin and (B) 0.1-20 weight % of syndiotactic polystyrene, the matting agent. The composition also includes (C) hydrogenated styrene block copolymer comprising styrene block and butadiene rubber block as a compatibilizer by 0.1-20 weight % for the total weight of the low surface gloss styrene resin composed of (A) the basic resin and (B) the matting agent and additionally includes (D) a plasticizer by 0.1-30 weight %. The composition of the present invention has excellent weatherability and impact-resistance in addition to the low surface gloss properties, so that it can be applied in various products, particularly exterior products for structures such as sidings and window frames, etc.
