Abstract: A customizable mattress topper system includes a first mattress topper of viscoelastic foam with a shaped top surface and a second foam mattress topper. The viscoelastic foam topper has a higher density than the second topper. The first mattress topper and second mattress topper are packaged and sold together as a system. The first mattress topper may be placed over the second mattress topper, or vice versa, and in various orientations over a bedding mattress as desired by a consumer to customize the level of cushioning support.

Abstract: A rebond polyurethane foam structure is formed by mixing shredded particles of polyurethane foam wherein at least 20% by weight of such particles comprise particles of viscoelastic polyurethane foam. The foam particles are wetted with a liquid prepolymer binder that is cured when the wetted admixture is compressed at a compression ratio of at least about 3. Despite the small viscoelastic foam particle size and the effects of compression and binder curing, the resulting polyurethane foam structure surprisingly has a viscoelastic (slow recovery) character.

Abstract: An upholstery construction for a mattress or an article of furniture includes a flame barrier foam sheet proximate to the back face of a surface fabric layer. The flame barrier foam sheet is formed by coating or impregnating a polyurethane sheet with an aqueous solution of one or more binder(s), such as but not limited to a polyvinyl chloride copolymer or an acrylic latex binder, and one or more flame retardant(s), such as but not limited to aluminum trihydrate or melamine. The flame barrier foam sheet with dried binder(s) and flame retardant(s) not only resists flame ignition but also retains its cushioning properties.

Abstract: Polyurethane foams formed under vacuum (below atmospheric pressure) conditions using toluene diisocyanate or a specific mixture of polyisocyanates with a specific mixture of polyether and graft polyols produces a foam with lower density and better flame retardancy than latex foam, but with equally high resiliency. The foam-forming ingredients are mixed together and foamed under controlled pressures in the range 0.6 to 0.95 bar (absolute), preferably 0.8 to 0.95 bar (absolute). The resulting foam has a ball rebound above about 65 percent.

Abstract: Polyurethane foams formed at above atmospheric pressure conditions using methylene diisocyanate or a specific mixture of polyisocyanate and with a major portion of methylene diisocyanate (MDI) with a specific mixture of polyether and graft polyols produces high density viscoelastic foams with improved hand touch (surface smoothness) that better retain viscoelasticity over time. The foam-forming ingredients are mixed together and foamed at controlled pressures in the range 1.05 to 1.5 bar (absolute), preferably 1.1 to 1.3 bar (absolute).

Abstract: Polyurethane foams formed using a specific mixture of polyether and graft polyols with toluene diisocyanate have fine cell size (over 70 pores per inch) and higher durability with IFD25 retention over 70% after 12,000 cycles of roll-shear. The foam-forming ingredients are mixed together and foamed at controlled pressures in the range 1.0 to 1.5 (absolute), preferably 1.05 to 1.5 bar (absolute). The foams make particularly good carpet cushions.

Abstract: Foaming a polyurethane foam at above atmospheric pressure conditions using a mixture of polyisocyanate and a specific mixture of low molecular weight (high OH number) polyether and graft polyols produces viscoelastic foams with high firmness, low energy losses and high temperature sensitivity such that firmness is reduced by at least 25% when the foam is heated from room temperature (e.g., about 70° F. (21° C.)) to 100° F. (38° C.). The foam-forming ingredients are mixed together and foamed at controlled pressures in the range 1.05 to 1.5 bar (absolute), preferably 1.1 to 1.3 bar (absolute).

Abstract: Polyurethane foams formed under vacuum (below atmospheric pressure) conditions using methylene diisocyanate or a specific mixture of polyisocyanate and with a major portion of methylene diisocyanate (MDI) with a specific mixture of polyether and graft polyols produces cushioning foams with lower density (1.4 to 1.8 pounds per cubic foot) and higher support factor (above 2.4). The foam-forming ingredients are mixed together and foamed under controlled pressures in the range 0.5 to 0.9 bar (absolute), preferably 0.6 to 0.8 bar (absolute). A major portion of the MDI is 4,4′ methylene diisocyanate.

Abstract: Polyurethane foams formed at elevated pressure using a graft polyol, or mixture of polyols to form a polyol system, having a low functionality and a high solids content, exhibit superior dynamic shock cushioning characteristics (energy absorption) as illustrated by the drop curves of deceleration versus static load. The foam-forming ingredients are mixed together and foamed under controlled pressures in the range of 1.2 to 1.5 bar, preferably 1.3 to 1.4 bar. The polyol preferably has a functionality in the range of about 2.0 to 2.5, a hydroxyl number in the range of about 50 to 90, a solids content above about 35%, preferably about 50 to 55%.
