Beschreibung
Zusammenfassung:	A thermoplastic resin composition of the present invention is characterized by comprising: a thermoplastic resin containing a rubber-modified vinyl-based graft copolymer and an aromatic vinyl-based copolymer resin; a polyalkylene glycol; zinc oxide having an average particle size of about 0.5 to about 3 μm and a specific surface area BET of about 1 to about 10 m2/g; and zinc phosphate. The thermoplastic resin composition and a molded article formed therefrom have excellent discoloration resistance, antibacterial properties, and acid resistance, even after exposure to ionizing radiation.
