  • Patent number: 10364329
    Abstract: The present invention relates to a thermoplastic resin composition. More particularly, the present invention relates a thermoplastic resin composition including 100 parts by weight of a base resin including (a) an aromatic vinyl compound-conjugated diene-based compound-vinyl cyan compound copolymer and (b) an aromatic vinyl compound-vinyl cyan compound copolymer; and (c) greater than 0.05 parts by weight and less than 11 parts by weight of a polyolefin oxide-based triblock copolymer, and a molded article including the same. In accordance with the present invention, the thermoplastic resin composition having superior chemical resistance and paintability with identical or superior impact strength, fluidity, and heat resistance, to conventional thermoplastic resin compositions, and a molded article including the same are provided.

  • Patent number: 10364346
    Abstract: Disclosed are an ABS-based resin composition and a molded article manufactured therefrom. More particularly, the ABS-based resin composition according to the present disclosure includes (a) 22.5 to 50% by weight of a vinyl cyan compound-conjugated diene-based rubber-like polymer-aromatic vinyl compound copolymer resin; (b) 47.5 to 75% by weight of an aromatic vinyl compound-vinyl cyan compound copolymer resin; (c) 1 to 6% by weight of a polyether ester amide resin; and (d) 1.5 to 3% by weight of an ethoxylated alkylamine-based antistatic agent, thereby providing a high humidification amount and less deformation. Accordingly, the present disclosure relates to an ABS-based resin composition suitable for application to disks for air washers, humidifiers, and the like, and a molded article manufactured therefrom.

  • Patent number: 10160851
    Abstract: The present invention relates to a styrene-based thermoplastic resin composition with improved flowability and, more specifically, a thermoplastic resin composition, which retains heat resistance and improved flowability by introducing a low-molecular weight styrene-acrylonitrile (SAN) resin into an acrylonitrile-butadiene-styrene (ABS) resin, which has enhanced heat resistance through the addition of a heat-resistant resin, and to a molded article into which the composition is molded. According to the resin composition, there can be obtained: a thermal resin composition, which has an improvement in the flowability of the heat-resistant ABS resin and retains non-deteriorating or favorable heat resistance and impact resistance; and a molded article.
