Abstract
A thermoplastic composition comprises: 35 to 45 weight percent of a branched, end capped polycarbonate, 55 to 70 weight percent of a poly(aliphatic ester-carbonate) having a weight average molecular weight of 15,000 to 25,000, a non-flourinated sulfonate salt flame retardant and a polysiloxane. Weight percent is based on the combined weight of the branched, end capped polycarbonate and poly(aliphatic ester-carbonate).
