Flame retardant polycarbonate compositions

Abstract

A flame retardant composition including A. 50 to 90 wt. % of a polycarbonate composition including from 15 to 85 wt. % based on the weight of the polycarbonate composition of a first polycarbonate and from 85 to 15 wt. % of a second polycarbonate, the first polycarbonate having a higher molecular weight than the second polycarbonate; B. 5 to 30 wt. % of glass fillers; C. 4 to 10 wt. % of a phosphazene compound; D. 0 to 10 wt. % of other components; wherein, the combined amounts of (A) to (D) is 100 wt. %, and wherein, the composition is selected to have: a heat distortion temperature of at least 110° C., as determined in accordance with ISO 75/A flatwise at a load of 1.8 MPa, and a flame retardancy of V-0 at a sample thickness of 0.8 millimeters when tested per UL-94 protocol.
