Title:
THERMOPLASTIC RESIN COMPOSITION AND MOLDED ARTICLE PRODUCED THERERFORM
Document Type and Number:
WIPO Patent Application WO/2019/190068
Kind Code:
A1
Abstract:
A thermoplastic resin composition of the present invention comprises: polypropylene resin; polyolefin copolymer resin; and zinc oxide, wherein the zinc oxide has an average particle size of about 0.5 to about 3 ㎛, a specific surface area BET of about 1 to about 10 m2/g, a 2θ peak position in the range of 35° to 37° in an X-ray diffraction (XRD) analysis, and a crystallite size value by formula 1 in the range of about 1,000 to about 2,000 Å. The thermoplastic resin composition has excellent antibacterial properties, impact resistance, chemical resistance, weather resistance, fluidity, etc.
