  • Polymeric sheets, methods for making and using the same, and articles comprising polymeric sheets
    Patent number: 10196494
    Abstract: In one embodiment, a polymeric sheet, comprising: a foamed layer comprising a polymeric material, wherein the polymeric material has a Tg of greater than or equal to 100° C.; and wherein the sheet has a weight reduction of 10% to 60%, as compared to a solid sheet of the same geometry and size formed from the same polymeric material. The sheet, at the thickness of 1.0 mm, has a smoke density of less than or equal to 200 particles after four minutes of burning according to ASTM E662-06. The sheet is thermoformable.
    Type: Grant
    Filed: February 21, 2014
    Date of Patent: February 5, 2019

  • Flame retardant polycarbonate compositions, method of manufacture thereof, and articles therefrom
    Patent number: 8691902
    Abstract: A thermoplastic polycarbonate composition includes, based on the total weight of the thermoplastic polycarbonate composition: 15 to less than 40 wt. % of a reinforcing mineral filler; and greater than 60 to 85 wt. % of a polymer component, including, based on the weight of the polymer component, 68 to 99.9 wt. % of an aromatic polycarbonate, 0.1 to 2 wt. % of a fluorinated polymer, optionally, 0.1 to 25 wt. % of an impact modifier; and optionally, 0.1 to 5 wt. % of an additive composition including an antioxidant, a mold release agent, and a stabilizer; wherein a molded sample of the thermoplastic polycarbonate composition has no drips when measured in accordance with NF P 92-505 at a thickness of 3.0 mm.
