Abstract
A thermoplastic composition includes a poly(etherimide-siloxane) copolymer having a siloxane content of more than 0 to less than 50 weight percent based on the total weight of the poly(etherimide-siloxane) copolymer; an aromatic polyketone; and a mineral filler having a particle diameter of 0.1-2 micrometers. The thermoplastic composition has a lower toxicity index than the same composition without the aromatic polyketone, the mineral filler, or both, as determined in accordance with EN53505.
Claims19
A thermoplastic composition comprising, based on the total weight of the composition,
- 25 to less than 95 weight percent poly(etherimide-siloxane) copolymer having a siloxane content of more than 0 to less than 50 weight percent based on the total weight of the poly(etherimide-siloxane) copolymer;
- 5-75 weight percent of an aromatic polyketone;
- and
- greater than 0 to 15 weight percent of a mineral filler comprising kaolin clay, talc, or a combination comprising at least one of the foregoing, wherein the mineral filler has a particle diameter of 0.1 to 2 micrometers;
- wherein the thermoplastic composition has a lower toxicity index than the same thermoplastic composition not including the aromatic ketone, the mineral filler, or both, as determined in accordance with EN 53505, or a lower HCN/benzene ratio than the same thermoplastic composition not including the aromatic polyketone, the mineral filler, or both.
A thermoplastic composition comprising, based on the total weight of the composition,
- 25 to less than 100 weight percent of a poly(etherimide-siloxane) copolymer having a siloxane content of more than 0 to less than 50 weight percent based on the total weight of the poly(etherimide-siloxane) copolymer;
- and
- greater than 0 to 15 weight percent of a mineral filler comprising kaolin clay, talc, or a combination comprising at least one of the foregoing, wherein the mineral filler has a particle diameter of 0.1 to 2 micrometers;
- wherein the thermoplastic composition has a lower toxicity index than the same thermoplastic composition not including the mineral filler, as determined in accordance with EN 53505, or a lower HCN/benzene ratio than the same thermoplastic composition not including the mineral filler.
