Hydrophilic polyurethane foam for water
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.
