  • Publication number: 20090054861
    Abstract: Compositions and methods for improving the adhesion of a film to a nonwoven, a film to another film, or a nonwoven to another nonwoven are disclosed. Depending on the laminate or multilaminate structure, the improvement can be achieved by using low viscosity, low density ethylene- or propylene-based polymers, which physically anchor to the substrate, such as a porous nonwoven, or by using a similar polymer in a blend with one of the substrate film polymers to improve flow and adhesion.

  • Publication number: 20080139714
    Abstract: This invention pertains to highly filled polymer compositions comprising a low molecular weight ethylene and/or alpha olefin homopolymers and copolymers, or blends therefrom, filled with high concentrations of fillers or additives. Examples of such fillers or additives include fire retardants, talc, ceramic manufacturing agents, color concentrates, crosslinking agents, and blowing agents. Because of the low crystallinity (and therefore high percentage of amorphous phase) and low viscosities of the base polymers, highly processable compositions can be formed containing even if containing relatively high loadings of fillers or additives. Such highly filled compositions are thus ideally suited as concentrates or masterbatch formulations for a variety of different compounding applications.

  • Patent number: 5422055
    Abstract: A process for preparing a fiber reinforced, glass matrix composite article of manufacture. The process employs an aqueous wet-laid technique by forming a dilute aqueous slurry of solids comprising glass fibers, reinforcing fibers and binder material which may be partially or completely fibrous. The dilute aqueous slurry is destabilized and the solids are collected on a porous support means. They are then dewatered and dried to form the composite mat which can be hot-pressed into an article of manufacture. The hot-pressed article of manufacture may then be heated, in the absence of pressure, to a temperature above the softening point of the glass, but below the degradation temperature of the reinforcing fibers, to provide a lofted composite.
