## Abstract The hydraulic permeabilities of open‐cell hydrophilic polyurethane (Hypol) foams have been measured at steady state over a preassure gradient range of 10^2^–10^4^dyn/cm^3^. These permeabilites were sensitive to the relative amounts of prepolymer, water, and surfactant, and to the mode o
