Abstract
A polycarbonate composition comprises: a first poly(carbonate-siloxane) copolymer, comprising a polysiloxane block with an average block length of 10 to 100, and a siloxane content from 5 wt % to 10 wt %; and a second poly(carbonate-siloxane) copolymer comprising a polysiloxane block with an average block length of 10 to 100, and a siloxane content from 30 wt % to 60 wt %; wherein the weight ratio of the first poly(carbonate-siloxane) copolymer to the second poly(carbonate-siloxane) copolymer is greater than or equal to 2 to less than 8; and a bisphenol A homopolycarbonate, wherein the polycarbonate composition has a total siloxane content of 2.5 wt % to 10 wt % based on the total weight of the composition; and a molded part of 1 mm thickness has a haze of less than 10% as measured by HazeGard (ASTM D1003-00).
