  • Patent number: 10240039
    Abstract: 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.

  • Patent number: 9908272
    Abstract: A method for making a thin wall component comprise: locating a film (40) in a mold cavity of a mold, wherein the mold cavity has an initial mold thickness, wherein the film comprises a base layer (41) and a pattern layer (42); injecting a molding material (60) into the mold cavity such that the molding material contacts the pattern layer, wherein the molding material comprises a polymeric material and a filler; compressing the mold to a final mold thickness that is less than the initial mold thickness, to form a molded product, wherein the pattern layer forms a surface of the molded product; and removing the molded product from the mold. A molded product formed by the method. The method produce a thin walled component without warpage, inner stresses, poor surface quality, or washout defects.

  • Publication number: 20170362731
    Abstract: Disclosed are platable resin compositions for use in, for example, metal plating of plastics. The resin compositions include polycarbonate, acrylonitrile butadiene styrene and a filler, and may exclude a laser direct structuring additive. The compositions possess markedly improved characteristics, such as notched IZOD impact, flex modulus, and peel strength. Also disclosed are methods for plating metal on a substrate that is formed from the present resin compositions, as well as articles that include the disclosed compositions.

  • Publication number: 20150232661
    Abstract: 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.
