  • Patent number: 10576429
    Abstract: Polyvinyl difluoride (PVDF) membranes prepared from casting solution including the biopolymer kappa-carrageenan (kCg) as an additive demonstrate improved structure and properties. The resulting asymmetrical structure has a thin layer on the upper surface, a porous sublayer with reduced volume of macro void space and increased porosity, and a spongy layer beneath the sublayer. This results in an increased hydrophilic nature, and provides enhanced wetting, membrane porosity, and water permeability—all important properties making these membranes suitable for a wide range of uses.

    Abstract: The present invention relates safing insulation and, particularly, to safing insulation with pre-applied smoke sealant and methods for using the same. In one exemplary embodiment, safing insulation sheets are formed from individual safing insulation sections having a layer of smoke sealant applied to the upper surface of the safing insulation sections. In order to form the safing insulation sheets, individual safing insulation sections are arranged with the fibers of each individual section extending in a vertical direction and a smoke sealant is applied thereto. The smoke sealant acts to mechanically secure the individual sections of safing insulation to one another and also eliminates the need to apply smoke sealant to the safing insulation after installation. Advantageously, by pre-applying the smoke sealant to the safing insulation, the need to use spraying equipment to apply the smoke sealant to the safing insulation at a job site is eliminated.

  • Publication number: 20130075016
    Abstract: The method forms a layered-open-network polishing pad useful for polishing at least one of magnetic, semiconductor and optical substrates. Exposing a first and second polymer sheet or film of a curable polymer to an energy source creates an exposure pattern in the first and second polymer sheet, the exposure pattern having elongated sections exposed to the energy source. Then removing polymer from the exposed first and second polymer sheets to forms elongated channels through the first and second polymer sheets in a channel pattern that corresponds to the exposure pattern. Attaching the first and second polymer sheets forms a polishing pad, the patterns of the first and second polymer sheets cross wherein the first polymer sheet supports the second polymer sheet and the elongated channels from the first and second polymer sheets connect and to form the layered-open-network polishing pad.

  • Patent number: 8303752
    Abstract: Provided is a method of manufacturing a wiring board, in which: a composite adhesive sheet 20 is attached to one of the surfaces of a support substrate 10, and a double-sided CCL 30 is attached to the other surface. Then, in an integrated state of the above components, a multilayer wiring structure including a conductive layer and a resin insulating layer is formed on a metal layer 33 of the double-sided CCL 30 by a known build-up method. A thermally foamable adhesive layer 22 of the composite adhesive sheet 20 is then heated, thereby thermally decomposing a thermal foaming agent to generate gas, and the support substrate 10 is separated from the remaining bonded body. Thereafter, a carrier foil layer 32b and a copper foil layer 32a of a carrier-foil coated copper foil 32 are mechanically peeled from each other at a boundary between both the layers, thereby obtaining a wiring board 1.

    Abstract: A method of fabricating a formed structure with expandable polymeric shell microspheres. A first plurality of polymeric shell microspheres are heated from an unexpanded state to an expanded state to form a plurality of expanded microspheres. The plurality of expanded microspheres are mixed with an epoxy resin and a second plurality of unexpanded polymeric shell microspheres. The mixture is formed in a shape to create a preform. The preform is wrapped with fiber tape to create a wrapped preform. The wrapped preform is placed in a mold. The mold is heated and the second plurality of unexpanded microspheres expand from an unexpanded state to an expanded state. The mold is cooled and the formed structure is removed from the mold.

  • Publication number: 20120193284
    Abstract: Method for preparing a filtration membrane and a filtration membrane prepared by the method. According to one embodiment, the method involves casting a polymer solution onto a porous support to form a coated support. The coated support is then quenched to form a membrane/support composite, and the membrane/support composite is then dried. Next, a first end of a first piece of adhesive tape is applied to the membrane side of the composite, and the second end of the first piece of adhesive tape is applied to a first rotatable winder. In addition, a first end of a second piece of adhesive tape is applied to the support side of the composite, and the second end of the second piece of adhesive tape is applied to a second rotatable winder. The two winders are then rotated so as to pull apart the membrane from the support.
