A method of making absorbent foam composites and absorbent foam composites produced therefrom. The method comprises casting an absorbent foam layer having a first side and a second side opposite the first side onto a barrier layer having a first side and second side opposite the first side, where the second side of the absorbent foam layer is in contact with the first side of the barrier layer; joining a second absorbent layer to the second side of the barrier layer before, during, or after the casting step; and breaching the barrier layer after the casting step so that the foam layer and second absorbent layer are in fluid communication. The absorbent foam composites can be used in a variety of applications, including personal hygiene articles, medical bandages, pet pads and agricultural pads.

The present invention relates to graphene-based foam, the graphene-based foam having a structure defined by a three-dimensional network of interconnected and ordered open cells, the open cells being defined by cell walls, the cell walls (i) being formed of graphene sheets, partially reduced graphene oxide sheets, reduced graphene oxide sheets, or a combination thereof, and (ii) having a thickness defined by the thickness of a plurality of graphene sheets, partially reduced graphene oxide sheets, reduced graphene oxide sheets, or a combination thereof.

According to one embodiment, a halogen free roof system is described. The roof system includes a structural deck that is positioned above joists or other support members. Polyisocyanurate foam insulation is positioned atop the structural deck. The polyisocyanurate foam insulation has an isocyanate index greater than 200 and includes a polyisocyanurate core having a halogen free fire retardant. A water proof membrane is positioned atop the polyisocyanurate foam insulation. The polyisocyanurate core is able to form a sufficiently stable char when exposed to flame conditions such that the polyisocyanurate core is able to pass the ASTM E-84 test.

A strongly scattering optoceramic converter material having a density of less than 97% is provided, as well as a method for producing such an optoceramic material. By appropriately choosing in particular the composition, blending method, and sintering conditions, the production method permits to produce converter materials with tailored properties.

A tire noise reduction device includes a sound absorbing member made of a porous material; and a band member disposed between the sound absorbing member and the tire inner surface and provided for attaching the sound absorbing member to a tire inner surface, the band member including chamfered portions on both surface sides at both ends in a width direction of the band member.

The plurality of pieces of low density cellular material, such as foam plastics, form a core panel having opposite side surfaces and with adjacent pieces having opposing edge surfaces extending between the side surfaces. Sheets of flexible material, such as veils or mats or scrim, are adhesively attached to the side surfaces, and portions of one sheet extend between the opposing adjacent edge surfaces for limiting flexing of the panel. The pieces may be tapered, and portions of the one sheet may project between the edge surfaces either partially or fully to form double wall webs. The webs may have flanges adhesively attached to the other sheet on the opposite side. One sheet may also be stretchable in areas not adhesively attached to the pieces to provide for curving the panel from a planar position maintained by the sheet on the opposite side.

An annular reinforcement structure is provided having an inner reinforcement band, an outer reinforcement band positioned around and concentric with the inner reinforcement band, and a cast-in-place polymer foam spacer, which maintains the spatial orientation of the inner and outer reinforcement bands. The annular reinforcement structure may be embedded in an elastomeric matrix material to provide stability, such as for belt for power transmission.

A fluoropolymer composite film wire or cable wrap comprises an outer layer of expanded polytetrafluoroethylene (ePTFE) and an inner layer of melt processable fluoropolymer film. The inner and outer layers are laminated with each other in tape form, such as by the application of heat and/or pressure thereto. The fluoropolymer composite tape is wrapped about one or more wires or cables, and is heated or sintered after wrapping to bond the tape to the wire or cable, and bond the tape to itself at the seams.

Aspects herein relate to apparel items and apparel systems that utilize applied or printed foam nodes to provide, among other things, stand-off between an apparel item and a wearer's skin surface. One or more of the foam nodes, or areas of the textile surrounding the foam nodes, may be perforated to provide a fluid communication path between an inner-facing surface and an outer-facing surface of the apparel item. The communication path may be used to facilitate air exchange between the external environment and the wearer's body and/or to provide an exit path for moisture vapor generated by the wearer.

Disclosed are porous resin particles which contain a polymer of a monomer mixture containing, as monomers, at least a monofunctional (meth)acrylic acid ester and a crosslinking monomer. The monofunctional (meth)acrylic acid ester accounts for 1 wt % to 50 wt % of the monomer mixture, and the crosslinking monomer accounts for 50 wt % to 99 wt % of the monomer mixture. The porous resin particles have a specific surface area of 190 m.sup.2/g to 300 m.sup.2/g and a bulk specific gravity of 0.25 g/mL to 0.45 g/mL.
