Abstract:
A polycarbonate composition contains, based on the total weight of the polycarbonate composition: one or more polycarbonate homopolymers; a poly(carbonate-siloxane) copolymer comprising siloxane units with an average block length of 5 to 120, preferably 10 to 100, the poly(carbonate-siloxane) copolymer being present in an amount effective to provide 2.5 to 10 wt % of siloxane units based on the total weight of the polycarbonate composition; 1 to 8 wt % of an elastomer-modified graft copolymer; 0.01 to 5 wt % of a silicone oil; and 0.1 to 8 wt % of an additive; and wherein the composition has a melt mass flow rate higher than 16 g/10 min, determined in accordance with ASTM D1238 under a load of 1.2 kg at 300° C. with a dwelling time of 300 seconds; and an Izod notched impact energy of at least 700 J/m measured at 23° C. on a sample of 3.2 mm thickness according to ASTM D256-10.
