Polycarbonate copolymer compositions for rail interiors

Abstract

A polycarbonate composition comprising: a polycarbonate comprising a homopolycarbonate, a poly(ester-carbonate-siloxane), a poly(aliphatic ester-carbonate), a poly(ester-carbonate-siloxane), a brominated polycarbonate, a poly(ester-carbonate), or a combination thereof and optionally, a poly(phthalate-carbonate); a poly(carbonate-siloxane) present in an amount effective to provide 1-10 wt % total siloxane, based on the total weight of the composition; 11-25 wt % of a reinforcing composition comprising 10-24 wt % glass fibers, and 1-10 wt % mineral filler comprising talc, kaolin, calcium carbonate, wollastonite, or a combination thereof; optionally, an organophosphorous flame retardant in amount effective to provide up to 1.5 wt % phosphorous; optionally, up to 10 wt % additive composition, wherein each amount is based on the total weight of the polycarbonate composition, which sums to 100 wt %.
