  • Publication number: 20110197543
    Abstract: The invention is directed to a composite foam material that is alkaline and heat resistance. The composite foam material comprises a foam layer that having a film layer attached thereto and in which at least one of the film or foam layers includes a carbon free radical scavenger agent that is dispersed therein. The carbon free radical scavengers neutralize free radicals that are generated in the polymeric material (e.g., film or foam layer) and help prevent the degradation of the foam composite material. In particular, foam composite materials in accordance with the present invention can be used in underlayment applications in which exposure to heat can degrade the underlayment. As a result, the durability and useful life of the composite sheet material can be extended. In some embodiments of the present invention provides a floor underlayment material that overcomes many of the problems discussed above.

  • 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: 20080311379
    Abstract: A reinforced low density material is provided that includes a reinforcing mesh or other geometry. The reinforcing mesh in one embodiment of the present invention is comprised of an arrangement of glass fibers that are coated with a polymer. The insulative material is formed by placing the reinforcing mesh within a mold, wherein the introduction of a heated expanded polystyrene, for example causes the coating on the reinforced mesh 1 to bond with the polystyrene to create a reinforced insulative material after the composite material cools.

  • Publication number: 20080292868
    Abstract: A shutter assembly, or other architectural structure or exterior/interior decorative trim element, having a foam insert at least partially enveloped by a cementitious shell. The assembly is molded from cementitious slurry, including gypsum cement and a latex/water mixture. An amount of the slurry is added onto a bottom mold surface portion to a desired depth and/or weight. The foam insert is provided with a plurality of spacer elements disposed in a surface thereof, which is placed atop the slurry in a desired orientation, whereupon an additional amount of the slurry is then added so as to at least partially envelop the foam core or insert. Engagement members on the top mold portion are then brought into contact with the spacer elements so that the foam insert remains at least partially submerged within the slurry. A top portion of the spacer elements can be removed from a base portion of the spacer element to reveal a bore formed in the base portion.
