    • The present invention relates to a polycarbonate resin composition that can have excellent light stability and dimensional stability, including: (A) 70 to 95 parts by weight of a thermoplastic polycarbonate resin; (B) 5 to 40 parts by weight of a thermoplastic non-crystalline polyester copolymer; (C) 5 to 50 parts by weight of titanium dioxide; (D) 0.1 to 10 parts by weight of an organic siloxane copolymer; and (E) 0.05 to 5 parts by weight of a fluorinated polyolefin-based resin. The polycarbonate resin composition can have excellent light stability and dimensional stability and also can have excellent mechanical strength without reduced impact strength and workability. The polycarbonate resin composition can be used in molded products such as LCD backlight parts requiring product dimensional stability and other parts requiring light stability.
    • 本发明涉及一种能够具有优异的光稳定性和尺寸稳定性的聚碳酸酯树脂组合物,其包括:(A)70〜95重量份的热塑性聚碳酸酯树脂; (B)5〜40重量份的热塑性非结晶性聚酯共聚物; (C)5〜50重量份的二氧化钛; (D)0.1〜10重量份有机硅氧烷共聚物; 和(E)0.05〜5重量份的氟化聚烯烃类树脂。 聚碳酸酯树脂组合物可以具有优异的光稳定性和尺寸稳定性,并且还可以具有优异的机械强度,而不降低冲击强度和加工性。 聚碳酸酯树脂组合物可用于需要产品尺寸稳定性的其它部件等需要光稳定性的液晶背光部件等成型品。
