  • Publication number: 20120045603
    Abstract: The invention relates to a foamed fluoropolymer, preferably a polyvinylidene fluoride (PVDF) structure, such as from Kynar® resins. The foamed structure is continuous self-supporting, sized, and has a dense skin. The foamed structure is manufactured in a process using foaming agents and nucleating agents. The structure is sized into a specific shape during the manufacturing process—requiring a good melt viscosity of the PVDF foam. In one process, a master batch containing the nucleating agent is used. The foamed article could be a sheet, film, profile, tube, pipe, article, rod foam-core structure, or other self-supporting shape. Foamed tubes, pipes, rods, sheets and conduit are especially useful. The foamed structure of the invention provides added value by being lighter weight, more flexible, and more impact resistant than a comparable non-foamed PVDF structure. It also has increased hysteresis, increased insulation properties, reduced dielectric constant, and increased compressibility.

  • Patent number: 8119082
    Abstract: Plastic test tube for taking blood samples, comprising a hollow tubular body and an adhesive protective film able to adhere to the tubular body. The tubular body is made of polyethylene terephthalate and has: a tubular wall which delimits a working volume and defines an outer surface; an open mouth for insertion of liquids at a first end of the wall; and a bottom for closing a second end of the wall. The adhesive protective film is able to adhere to the wall of the tubular body over at least a portion of the outer surface. The test tube is characterized in that the wall of the tubular body has a thickness in the range of 1 to 3 mm and in that the protective film is defined by a layer of polypropylene, polyethylene or copolymers thereof. The layer has a thickness in the range of between 40 and 60 ?m and is able to form a liquid barrier.

  • Publication number: 20120040122
    Abstract: A temporary part is fixed to a base by using an adhesive layer to which fillers are mixed at a predetermined density. When the temporary part is heated, heat is applied to the fillers and the adhesive layer. At a temperature equal to or higher than the glass-transition temperature of the adhesive agent, the heated adhesive layer is thermally contracted so as to release remaining stress, and on the other hand, the heated fillers are thermally expanded. In this manner, the peel-off strength between the adhesive layer and the base (or the temporary part) is reduced, and the disassembly is facilitated.

    Abstract: The present invention has its object to provide a resin composition for tubes excellent in balance among wear resistance, flexibility, gas permeation resistance and low resilience (pliability). The object is accomplished by a resin composition for tubes which comprises an isobutylene block copolymer (A) constituted of a polymer block (a) derived from isobutylene as a main constituent and a polymer block (b) derived from a monomer component other than isobutylene as a main constituent, and a thermoplastic polyurethane resin (B).

  • Patent number: 8057877
    Abstract: A flexible hose for transporting food liquids, particularly for irrigation or the like, comprising at least one outer protective layer (2) of a first flexible polymer material and at least one inner layer (3) in direct contact with the fluid to be transported, made of a second flexible polyvinyl chloride (PVC)-containing polymer material. The second polymer material includes a plasticizer agent having as low a migration level as to maintain the flexibility of said second polymer material substantially unaltered with time. The plasticizer agent is selected from the group comprising non-phthalate additives, so that it can be non-toxic and non-polluting for the food products to be transported.

  • Patent number: 8053069
    Abstract: A composite material being excellent in heat conductivity is provided. In order to realize this, a fibrous carbon material made of fine tube form structures constituted with single-layer or multiple-layer graphene is present to form a plurality of layers within a substrate made from a spark plasma sintered body of a metal powder, a mixed powder of a metal and ceramics, or a ceramic powder. The fibrous carbon material constituting each layer is made of a mixture obtained by mixing a small amount of a small diameter fiber 2 having an average diameter of 100 nm or less with a large diameter fiber 1 having an average diameter of 500 nm to 100 ?m.

  • Patent number: 8046960
    Abstract: A window includes first and second panes and a frame coupled to the first and second panes to form an air gap there between. The window further includes an electrical generator disposed in the air gap configured to convert electromagnetic radiation to electricity. The window further includes a venting system configured to vent heat from the air gap away from the first pane or the second pane. The window further includes first and second reflective coatings respectively disposed on first surfaces of the panes. The first surfaces face the air gap, and the reflective coatings are configured to reflect infrared radiation into the air gap. The window further includes first and second antireflective coatings respectively disposed on second surfaces of the panes. The second surfaces face away from the air gap, and the antireflective coatings are configured to transmit visible light and infrared radiation into the air gap.

  • Patent number: 8048351
    Abstract: A hose for use in bio-pharmaceutical applications includes an innermost tubular layer made from a fluoropolymer material. The tubular layer has an inner, relatively smooth and pure surface that defines an opening for transfer of various media. A layer of silicone is disposed next to an outer surface of the innermost tubular layer through use of, for example, an extrusion method. The outer surface of the tubular layer may first be modified by various treatments or chemicals to facilitate the adhesion of the silicone layer thereto. The silicone material may be solid or foamed. A reinforcement layer may be disposed adjacent to an outer surface of the silicone layer. The reinforcement layer may be formed of a wire braid having gaps. An outer jacket of silicone may be attached to the reinforcement layer and to the inner silicone layer through the gaps in the reinforcement layer.
