    Abstract: The present disclosure relates to a thermoplastic resin composition and an exterior material including the same. The thermoplastic resin composition included 90 to 99.5% by weight of styrene-based resins each including 5 to 30% by weight of acrylate rubber having a DLS average particle diameter of 0.25 to 0.32 μm or a TEM average particle diameter of 0.2 to 0.27 μm based on a total weight of the styrene-based resins; and 0.5 to 10% by weight of a polyamide resin, and an exterior material including the thermoplastic resin composition. According to the present disclosure, a low-gloss thermoplastic resin composition having excellent aesthetics, such as softness, luxuriousness, and naturalness, due to uniformity, low gloss, and improvement in surface texture while having mechanical properties and processability equal or superior to those of conventional ASA resins; and an exterior material including the low-gloss thermoplastic resin composition may be provided.

    Abstract: The present disclosure relates to a thermoplastic resin composition and a molded article including the same. The present disclosure relates to a thermoplastic resin composition including two or more types of acrylic graft resins (A) having different average particle diameters; a first copolymer (B) including an alkyl-substituted styrene, a (meth)acrylate, and a vinyl cyanide compound; a second copolymer (C) including an alkyl-unsubstituted styrene, a (meth)acrylate, and a vinyl cyanide compound; and a (meth)acrylate polymer (D), wherein the (meth)acrylate is included in an amount of 40 to 59% by weight based on a total weight of the thermoplastic resin composition, and a molded article including the thermoplastic resin composition. The thermoplastic resin composition having these compositional features may have excellent impact resistance, fluidity, and heat resistance, and may provide an economic advantage by suppressing increase in processing cost. In particular, the thermoplastic resin composition may implement a deep black color.

    Abstract: The present invention relates to a thermoplastic resin composition, a method of preparing the same, and a molded article manufactured using the same. More specifically, the thermoplastic resin composition of the present invention includes 100 parts by weight of a base resin consisting of an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-1) containing acrylate rubber having an average particle diameter of 0.05 to 0.15 μm as a core, an acrylate-aromatic vinyl compound-vinyl cyanide compound graft copolymer (A-2) containing acrylate rubber having an average particle diameter of 0.3 to 0.6 μm as a core, an aromatic vinyl polymer (B-1), and a heat-resistant aromatic vinyl polymer (B-2); and 0.5 to 10 parts by weight of a polyolefin elastomer (C). Within this range, the thermoplastic resin composition may have a heat deflection temperature (HDT) of 89° C. or more.

    Abstract: The present disclosure relates to a thermoplastic resin composition and a molded article including the same. More particularly, the present disclosure relates to a thermoplastic resin composition including 100 parts by weight of a styrene-based resin and 1 to 10 parts by weight of a surface modifier and having a skewness (Rsk) of 0.65 to 1.35 and a molded article including the thermoplastic resin composition. In addition, the present disclosure provides a thermoplastic resin composition that is capable of imparting a rough feeling to the surface of a product and has excellent weather resistance while maintaining mechanical properties and processability equal or superior to those of conventional ASA resins; and a molded article including the thermoplastic resin composition. In particular, due to these properties of the thermoplastic resin composition, a product manufactured using the thermoplastic resin composition may have a luxurious appearance without an artificial plastic feel.
