    Abstract: The present invention provides a process for effectively extruding a polypropylene polymer onto a cellulosic substrate. In the process, a polypropylene polymer is co-extruded with a polyolefin polymer other than polypropylene so as to stabilize the molten polypropylene polymer layer. Co-extrusion also allows extruding the polypropylene polymer at elevated temperatures so that the polypropylene is oxidized. Thus the polypropylene layer more readily bonds to a substrate without requiring a primer or ozone pretreatment step.

    Abstract: A pitch coated board and method of manufacture are disclosed. A porous or fibrous material, is coated and partially impregnated with a thin layer, less than 10 mil in thickness, of a petroleum or coal tar pitch. A high softening point, above 200F, coal tar or petroleum pitch is heated, then preferably roller coated on a fibrous material, then cooled within 1-2 seconds or less, to produce the pitch coated material. The porous material may be heated, preferably superficially, prior to application of the pitch to facilitate some penetration.

  • Publication number: 20020168508
    Abstract: A polymer-impregnated paper-based web for use as a medical packaging bacteria barrier fabric is provided. The use of a particular type of polymer emulsion as the saturant provides the effective range of bacteria filtration while at the same time allowing the web to maintain its enhanced strength and delamination resistance that are required when such substrates are employed to wrap surgical trays, surgical instruments, medical appliances and the like prior to sterilization. The invention consists of a paper-containing medical packaging substrate that has been saturated with a polymer having a glass transition temperature of −20° C. or less.

  • Patent number: 6468645
    Abstract: A molded fiber product is made from plant fibers containing lignin. Plant fibers ranging in size below 0.5 mm are used. Binding agents and other additives may be mixed with the fibers to enhance product or process performance. The plant fiber mixture of fibers and additives are heated at temperatures between 40 degrees C. and 300 degrees C. The heated fibers are compressed in a mold to an average density of at least 960 kg/m3. Compression pressures of at least 3.4 MPa are used. The compressed fiber product is released from the mold and the mold may be reused. A thermoset molded plant fiber product is provided having characteristics and qualities similar to engineering grade thermoplastics and thermoset plastics.

  • Patent number: 6468382
    Abstract: Packing material with good gas barrier properties comprising a first and a second layer of a fibrous material or, e.g. paper or cardboard, and a layer of a water based polymer, e.g. polyvinyl alcohol, placed between and in direct contact with the layers of fibrous material and functioning both as a gas barrier and as a binding agent in the packaging material. The packaging material is produced through bringing together and binding together with each other a first and a second strip or sheet of a fibrous material by means of a layer of a water based polymer, e.g polyvinyl alcohol, applied between and in direct contact with the strips or sheets. The surplus water in the thus applied polymer layer is absorbed by the fibrous material in one and/or the other strip or sheet to form the intermediate layer functioning as gas barrier and binding agent.

  • Patent number: 6406782
    Abstract: A multi-layer article which may be provided in the form of a tape comprises a conformable, compressible, melt flow-resistant core layer having first and second major surfaces, a sealant layer on the first major surface of the core layer, and optionally a bonding layer on the second major surface of the core layer. The sealant layer and the bonding layer each have a surface available for contacting a separate substrate. Various thermoset and foam core layers are disclosed as are thermosettable and thermoplastic sealant layers. The articles are useful for sealing two substrates together, particularly where one of the substrates is glass. Thus, the articles are especially adapted for sealing motor vehicle windshields to a frame. Various assemblies and methods for producing the same are also described.

  • Patent number: 6325969
    Abstract: The present invention provides a porous paper product impregnated with at least one chemical species. The porous paper product can be in the form of sheets, or compressed pellets. The porous paper can be prepared from a variety of sources, including wood pulp, kenaf, flax, or hemp. The chemical species impregnating the paper react and/or diffuse out of the paper to accomplish a variety of desired results. For example, diffusion of a volatile biocidal chemical out of pores in the paper create a no-growth zone on and immediately surrounding the impregnated paper. In this manner the impregnated paper can provide a sterile environment for activities such as food packaging/storage, the treatment of illness/injury, or waste disposal.

  • Patent number: 6265058
    Abstract: The present invention is a dielectric film, and method for making the film, suitable for use in the construction of capacitor devices, including wound capacitors. In order to overcome strength limitations associated with polymers having desirable dielectric properties, the invention includes a dielectric film featuring a polymer impregnated upon a strengthening substrate. The polymer is deposited directly upon the substrate, which substrate provides required physical strength for film processing and capacitor fabrication, without compromising dielectric performance. The inventive film is based on siloxane polymers modified with polar pendant groups to provide a significant increase in dielectric constant and dielectric strength. During film production, the polymer infiltrates the porous paper to provide an interfacial composite layer between the two materials, the interfacial layer consisting of polymer and paper.
