In various aspects, the disclosure relates to thermally conductive thermoplastic compositions comprising a polymer matrix, an impact modifier composition having a chemically reactive impact modifier, and, optionally, a chemically non-reactive impact modifier, and a thermally conductive filler. The disclosed thermally conductive thermoplastic compositions exhibit good thermal conductivity and improved impact and ductile properties.

Thermal conductive compositions having good impact performance

The disclosure concerns blended thermoplastic compositions comprising (a) from about 50 wt % to about 80 wt % of a polycarbonate component; (b) from greater than 0 wt % to about 12 wt % of an impact modifier component; (c) from about 10 wt % to about 40 wt % of a filler; and (d) from about 5 wt % to about 15 wt % of a flame retardant component comprising an oligomeric phosphate ester, wherein the oligomeric phosphate ester is a free flowing powder at 23&#xb0; C.; wherein the blended thermoplastic composition has a ductility of 100% at 10&#xb0; C. when measured by a Notched Izod Impact test performed according to ASTM D256; wherein the combined weight percent value of all components does not exceed 100 wt %; and wherein all weight percent values are based on the total weight of the composition.

Reinforced polycarbonate compositions

A polymer composition includes: about 20 wt % to about 80 wt % of a polycarbonate polymer; about 1 wt % to about 20 wt % of a polycarbonate-siloxane copolymer; about 15 wt % to about 35 wt % of a reinforcing filler having a tensile modulus of at least about 150 GPa; and about 4 wt % to about 20 wt % of a flame retardant comprising phosphorous. The polymer composition demonstrates a flexural modulus in an amount equal to or greater than about 10 GPa. Methods of forming a polymer composition and blended thermoplastic compositions are also described.

Reinforced flame retardant polycarbonate composition and molded article comprising same

A composition includes specific amounts of an aromatic polycarbonate, a block polycarbonate-polysiloxane, a poly(alkylene terephthalate), a block polyestercarbonate, and an organophosphate ester. Relative to a corresponding composition lacking the block polyestercarbonate, the composition exhibits improved solvent resistance while substantially maintaining impact strength, melt flow, and flame retardancy. The composition is useful for fabricating articles that may come into contact with liquid chemicals or chemical vapors.

Polyester-polycarbonate composition and article

The invention concerns polymer compositions comprising 20-80 weight percent polycarbonate polymer, 15-40 weight percent filler and 4-20% flame retardant and articles comprising same.
