Abstract
A thermoplastic composition comprisese: 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).
Claims20
A thermoplastic composition comprising:
- 35 to 45 weight percent of a branched, end capped polycarbonate;
- 55 to 65 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, wherein weight percent is based on the combined weight of the branched, end capped polycarbonate and poly(aliphatic ester-carbonate).
2 more elements
A thermoplastic composition comprising:
- 30 to 45 weight percent of a branched, end capped polycarbonate, 55 to 70 weight percent of a combination of a first poly(aliphatic ester-carbonate) having a weight average molecular weight of 15,000 to 25,000 and a second poly(aliphatic ester-carbonate) having a weight average molecular weight of 30,000 to 40,000, a non-flourinated sulfonate salt flame retardant and a polysiloxane wherein the weight ratio of the first poly(aliphatic ester-carbonate) to the second poly(aliphatic ester-carbonate) is 3:4 to 5:2 and weight percent is based on the combined weight of the branched, end capped polycarbonate and poly(aliphatic ester-carbonate).
