Abstract: A thermoplastic polycarbonate composition comprising: 5 to 28 wt % of a brominated polycarbonate; 45 to 90 wt % of a homopolycarbonate having a weight average molecular weight from 20,000-25,000 grams/mole as measured via gel permeation chromathography using bisphenol A homopolycarbonate standards; 0 to 15 wt % of an aromatic poly(ester-carbonate) comprising carbonate units derived from bisphenol A, resorcinol, or a combination thereof, and ester units derived from a bisphenol, preferably bisphenol A, or resorcinol, and terephthalic acid, isoterephthalic acid, or a combination thereof, wherein a molar ratio of carbonate units to ester units ranges from 1:99 to 99:1; 2 to 10 wt % of a core-shell impact modifier; 1 to 7 wt % of an α,β-unsaturated glycidyl ester copolymer impact modifier; 0.6 to 3.5 wt % color composition comprising titanium dioxide and carbon black; wherein the wt % of each component is based on the total weight of the composition, which totals 100 wt %.
