  • Patent number: 11118052
    Abstract: Thermoplastic compositions include: (a) a thermoplastic polymer including a polycarbonate component; (b) a poly(carbonate-siloxane) copolymer; and (c) from 4 wt % to 25 wt % carbon black. The composition has a total siloxane content of from 2 wt % to 14 wt %. The thermoplastic compositions exhibit improved physical properties as compared to compositions that do not include the poly(carbonate-siloxane) copolymer, including volume resistivity, melt viscosity, impact strength, puncture impact energy and surface resistivity.
    Type: Grant
    Filed: December 21, 2020
    Date of Patent: September 14, 2021

  • Patent number: 9567461
    Abstract: A composition is prepared by melt blending specific amounts of components including a poly(phenylene ether), a first hydrogenated block copolymer (HBC1) that includes a polystyrene-poly(ethylene-butylene)-polystyrene triblock copolymer having a polystyrene content of 50 to 75 weight percent, and a second hydrogenated block copolymer. The second hydrogenated block copolymer can selected from five different hydrogenated block copolymer types and their combinations. The composition exhibits high light transmittance, low haze, and high impact strength at low temperature, which make it useful for molding objects such as containers for storage in refrigerators and freezers.

  • Publication number: 20140088236
    Abstract: A composition includes 15 to 35 weight percent of a poly(phenylene ether) having an intrinsic viscosity of 0.29 to 0.43 deciliter per gram, and 65 to 85 weight percent of a rubber-modified polystyrene. The composition exhibits improved heat resistance relative to acrylonitrile-butadiene-styrene copolymer (ABS) while maintaining comparable levels of melt flow, impact resistance, and tensile strength. Articles such as electrical housings can be molded from the composition.

  • Publication number: 20140045979
    Abstract: A composition having a combination of high heat resistance, high impact strength, and high flame retardance includes specific amounts of poly(phenylene ether), hydrogenated block copolymer, and organophosphate flame retardant. The composition has minimal amounts or excludes certain styrenic polymers, polyolefins, and reinforcing fillers. Also disclosed are injection molded articles formed from the composition. The composition is particularly useful as a molding composition for photovoltaic junction boxes and connectors.
