Abstract
The present disclosure relates to a thermoplastic resin composition and an exterior material including the same. The thermoplastic resin composition includes 100 parts by weight of styrene-based resins; 0.5 to 5 parts by weight of a first polyamide resin having a melting temperature (Tm) of 230° C. or less; and 0.5 to 10 parts by weight of a second polyamide resin having a melting temperature (Tm) of 250° C. or more. Both the first and second polyamide resins have a relative viscosity of 2.5 or less. The present disclosure advantageously provides a low-gloss thermoplastic resin composition having excellent aesthetics, such as softness, luxuriousness, and naturalness, due to uniform and 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.
