摘要:
A composition includes specific amounts of an aromatic polycarbonate, an impact modifier, a black colorant, and a copolyester or a block polyestercarbonate or a combination of the copolyester and the block polyestercarbonate. The composition exhibits increased gloss and decreased haze relative to a corresponding composition without the copolyester or the block polyestercarbonate. The composition is useful for fabricating parts such as television bezels, covers of computer gaming consoles, and mobile phone front bezels and back covers.
摘要:
In various aspects, the disclosure relates to reinforced thermoplastic compositions exhibiting improved physical properties as well as thin wall flame resistance. The reinforced thermoplastic compositions comprise polycarbonate polymer, a filler, and a polyolefin elastomer.
摘要:
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° C.; wherein the blended thermoplastic composition has a ductility of 100% at 10° 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.
摘要:
Disclosed herein are blended thermoplastic compositions comprising at least one polycarbonate component, at least one impact modifier, at least one mineral filler, and at least one flame retardant. The resulting compositions can be used in the manufacture of articles requiring materials with high modulus, ultra-high ductility, good flow, thin wall flame retardancy and good thermal resistance. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
摘要:
Disclosed herein is a flame retardant composition comprising 10 to 90 weight percent of a linear polycarbonate; a branched polycarbonate; 10 to 70 weight percent of a polysiloxane-polycarbonate copolymer where the polysiloxane-polycarbonate copolymer comprises 10 weight percent or less of polysiloxane having a weight average molecular weight of less than 30,000 Daltons; and 1 to 20 weight percent of a phosphazene compound; were all weight percents are based on the total weight of the composition, and where the composition does not contain a flame retardant other than the phosphazene compound. Disclosed herein too is a method comprising blending 10 to 90 weight percent of a linear polycarbonate; a branched polycarbonate; 10 to 70 weight percent of a polysiloxane-polycarbonate copolymer where the polysiloxane-polycarbonate copolymer comprises 10 weight percent or less of polysiloxane having a weight average molecular weight of less than 30,000 Daltons; and 1 to 20 weight percent of a phosphazene compound; to form a flame retardant composition; were all weight percents are based on the total weight of the composition, and where the composition does not contain a flame retardant other than the phosphazene compound.
