Abstract:
In an embodiment, a reflector comprises a polycarbonate composition, the polycarbonate composition comprises: polycarbonate; 10 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. A molded article of the polycarbonate has transmission level greater than or equal to 90.0% at 2.5 mm thickness as measured by ASTM D1003-00 and a yellow index (YI) less than or equal to 1.5 as measured by ASTM D1925.
