Abstract: Hydrophilic composite structures are made by impregnating a 3DL structure with a polyurethane foam formulation and curing the formulation to produce a foam that occupies the spaces in the 3DL structure. The composite structures have an unusually good capacity for retaining water even when under compressive forces. They also exhibit at most moderate swelling when saturated with water. The foam is useful as a layer of a water containment system such as a green roof or blue roof system.

Abstract: Hydrophilic polyurethane foam is made from a diphenylmethane-based quasi-prepolymer having specified isocyanate and oxyethylene contents. The foams have an unusually good capacity for retaining water even when under compressive forces. They also exhibit at most moderate swelling when saturated with water. The foam is useful as a layer of a water containment system such as a green roof or blue roof system.

Abstract: A reaction system for forming a hydrophilic polyurethane foam for liquid based cleaning applications includes a composition that has a prepolymer component and an aqueous component. The prepolymer component is a reaction product of an isocyanate component that includes diphenylemethane diisocyanate (MDI) and a polyol component that includes a polyoxyethylene-polyoxypropylene polyol that has an polyoxyethylene content greater than 65 wt %, based on a total weight of the polyoxyethylene-polyoxypropylene polyol. The aqueous component includes at least 60 wt % of water and at least 0.5 wt % of a surfactant, based on a total weight of the aqueous component. A weight ratio of the prepolymer component to the aqueous component in the composition is from 0.5:2 to 2:0.5, the composition has a cream time of less than 20 seconds and a tack free time of less than 7 minutes, and the hydrophilic polyurethane foam for liquid based cleaning applications has a wet tear strength of at least 500 N/m.

Abstract: Sponges for cosmetic and/or medicinal applications are coated with a surface coating. The surface coating contains an elastomeric, non-silicone polymer, a certain silicone polymer, an encapsulated phase change material and optionally ceramic particles. The coated sponges have desirable haptic properties and efficiently absorb and release make-up and medicines for application to the skin.
