  • Publication number: 20230203266
    Abstract: A flexible foam composition includes a flexible foam body having a surface, which flexible foam is polyurethane and/or latex flexible foam, and an expandable graphite layer on the surface or within the foam surface adjacent to the surface. The flexible foam composition with the expandable graphite layer imparts improved flame retardant properties to the composition.

  • Publication number: 20230174838
    Abstract: A flexible cellular foam or fabric product is coated with a coating including highly thermally conductive nanomaterials. The highly thermally conductive nanomaterials may be carbon nanomaterials, metallic, or non-metallic solids. The carbon nanomaterials may include, but are not necessarily limited to, carbon nanotubes and graphene nanoplatelets. The highly thermally conductive nanomaterials may include but are not limited to nano-sized solids that may include graphite flakes, for example. When coated on a surface of flexible foam, the presence of nanomaterials may impart greater thermal effusivity, greater thermal conductivity, and/or a combination of these improvements. The flexible foam product may be polyurethane foam, latex foam, polyether polyurethane foam, viscoelastic foam, high resilient foam, polyester polyurethane foam, foamed polyethylene, foamed polypropylene, expanded polystyrene, foamed silicone, melamine foam, among others.

  • Publication number: 20220259478
    Abstract: A flexible foam composition comprising a flexible foam structure comprising a plurality of struts, and a plurality of fibers, where a majority of the fibers are associated with the struts. The fibers may be thermally conductive fibers. The fibers include, but are not necessarily limited to, homopolymer and/or copolymer fibers having a glass transition temperature (Tg) of ?50° C. (?58° F.) or greater, carbon fibers, animal-based fibers, plant-based fibers, metal fibers, and combinations thereof. The presence of fibers can impart to the flexible foam composition greater indentation force deflection (IFD), greater static thermal conductivity, improved compression set, improved height retention or durability, and/or a combination of these improvements.

  • Patent number: 10486341
    Abstract: Methods and combinations of a curing catalyst with a mold release mixture, which is then subsequently applied to the surface of a mold prior to the application of polyurethane reactants to said mold, where the curing catalyst component has the effect of catalyzing the reaction at the surface of the molded part. This catalysis results in greater reactivity at the surface between reacting portions and lower delamination of the surface of the foam, thereby leading to more attractive skins with a more consistent cell structure, and lower de-mold times due to skins whose nature makes them less likely to adhere to the surface of the mold. These foams will be less likely to tear upon opening of the mold, and production quality and output will be improved.

  • Patent number: 10344134
    Abstract: Combinations of gelatinous elastomer and polyurethane foam may be made by introducing a plasticized A-B-A triblock copolymer resin and/or an A-B diblock copolymer resin into a mixture of polyurethane foam forming components including a polyol and an isocyanate. The plasticized copolymer resin is polymerized to form the gelatinous elastomer in-situ while simultaneously polymerizing the polyol and the isocyanate to form polyurethane foam. The polyurethane reaction is exothermic and can generate sufficient temperature to melt the styrene-portion of the A-B-A triblock copolymer resin thereby extending the crosslinking and in some cases integrating the A-B-A triblock copolymer within the polyurethane polymer matrix. The combination has a marbled appearance. The gel component has higher heat capacity than polyurethane foam and thus has good thermal conductivity and acts as a heat sink. Another advantage of in situ gel-foam is that the gel component provides higher support factors compared to the base foam alone.
