摘要：
In an embodiment, a polycarbonate composition comprises: polycarbonate; 7 wt % to 20 wt % titanium dioxide, based upon a total weight of the polycarbonate composition; an optional flame retardant; and an optional UV stabilizer. A plaque formed from the polycarbonate composition has a reflectance of greater than or equal to 95%, as determined by reflectance measurements using a Gretag Macbeth Coloreye spectrophotometer (D65 light source, 10 degree observer, UV included) made at a wavelength of 680 nm. In an embodiment, a polycarbonate composition comprises: a polycarbonate; 7 to 20 wt % titanium dioxide; a flame retardant; and an optional UV stabilizer; wherein the polycarbonate composition has a maximum reflectance of greater than or equal to 95%. The melt volume rate as determined at 300° C. using a 1.2 kilogram weight, in accordance with ASTM D1238-04 is from 5 to 30 grams per 10 minutes.
