Abstract: An open cell polyurea polyurethane foamed sponge is produced by mixing together a resin and an aqueous pahse. The resin phase consists of a prepolymer made from a hydrophilic oxyalkylene polyol which is capped with isocyanate groups and from about 1-30% by weight of the prepolymer of a polymeric polysocyanate such as a PAPI resin. The aqueous phase contains water, reinforcing fibers, surfactants, a thickening agent and preferably up to 40% by weight of diatomaceous earth. The resulting foam has a reduced volume swell, rapid wet out and improved wet strength.
