Synthetic Resin Or Polymer Patents (Class 428/349)
  • Patent number: 10414105
    Abstract: The invention relates to use of polylactide (PLA) as an extruded polymer coating on paper or board intended for the production of containers and packages, which are heated in a stove or microwave oven. According to the invention a polyfunctional cross-linking agent, such as trialkyl isocyanurate (TAIC), is blended with PLA, and the extruded coating layer is subjected to cross-linking electron beam (EB) radiation. PLA may be used as such or blended with another biodegradable polyester such as polybutylene succinate (PBS). EB radiation has been found to improve adhesion of the coating to the paper or board substrate, heat-scalability of the coating, and heat-resistance of the finished containers and packages.

  • Patent number: 10315404
    Abstract: A method for surface preparation of composite substrates prior to adhesive bonding. A curable surface treatment layer is applied onto a curable, resin-based composite substrate, followed by co-curing. After co-curing, the composite substrate is fully cured but the surface treatment layer remains partially cured. The surface treatment layer may be a resin film or a removal peel ply composed of resin-impregnated fabric. After surface preparation, the composite substrate is provided with a chemically-active, bondable surface that can be adhesively bonded to another composite substrate to form a covalently-bonded structure.

  • Patent number: 8956556
    Abstract: The present application is directed to dielectric isolators for use in aircraft fuel systems to control lightning induced current and allow dissipation of electrostatic charge. The dielectric isolators are configured to have a high enough impedance to limit lightning currents to low levels, but low enough impedance to allow electrostatic charge to dissipate without allowing buildup. Although the dielectric isolators may develop a potential difference across the dielectric length due to the effects of lightning currents and its inherent impedance, they are configured to withstand these induced voltages without dielectric breakdown or performance degradation. In one embodiment, the dielectric isolator includes a tube constructed of a composition including a thermoplastic organic polymer (e.g., PEEK) and carbon nanotubes, and a pair of fittings attached to opposing ends of the tube.

  • Publication number: 20150044456
    Abstract: Articles and laminates include a substrate with a first polyester surface and a second polyester surface, a crosslinked polyurethane-based primer coated on at least the first polyester surface, and an optically clear heat activated adhesive adjacent to the crosslinked polyurethane-based primer. The articles and laminates are prepared by applying a polyurethane-based dispersion and a crosslinker on at least one polyester surface, drying the applied coating, heating while stretching the substrate and the coating to form a crosslinked primer layer on the stretched polyester surface, and applying an optically clear heat activated adhesive onto the crosslinked primer layer.

    Abstract: The multilayer film comprises a first outer layer which is heat sealable. The first outer layer comprises from 95 to 100 percent (by weight of the first outer layer) of a first polymer, said first polymer being derived from propylene monomer and optionally one or more comonomers selected from the group consisting of ethylene and C4-C8 alpha olefins. The first polymer should have a melting point of at least 125 C. The multilayer film further comprises an inner portion adjacent to the first outer layer. The inner portion may be a single layer or may comprise several layers. At least one layer of the inner portion comprises an elastomeric propylene based polymer (“EPBP”). Further at least one layer of the inner portion comprises a second polymer, wherein the second polymer is selected from the group consisting of high pressure low density polyethylene, high density polyethylene, ethylene acrylic acid copolymers, ethylene (meth)acrylic acid copolymers and combinations thereof.
