Abstract:
1. A thermoplastic composition, comprising: 30 to 50 wt.% of a polycarbonate; 15 to 35 wt.% of a polyester carbonate; 25 to 35 wt.% of an impact modifier; polycarbonate-polysiloxane copolymer; and 0 to 10 wt.% of an aromatic vinyl copolymer; based on the total combined weight of the polycarbonate, polyester carbonate, impact modifier and aromatic vinyl copolymer, wherein the composition has a Notched Izod impact value at −20° C. of greater than 20 kJ/m wherein the composition has a Melt Stability between −10% and +10% when measured as the percent shift in Melt Volume Rate from a 6 minute preheat to an 18 minute preheat, when measured according to ASTM D1238 at 260° C. using a 5 kilogram weight over 10 minutes.
