  • Open cell rigid thermoset foams and method
    Patent number: 4454248
    Abstract: A rigid porous, deformation resisting, nonresilient inflexible thermoset resin foam having macroscopic open cells and the method of making the same. The method comprises foaming and partially curing a polyepoxide or polyurethane resin in which the cells are closed. The partially cured resin is softened by heating and then crushed to compress the cells to produce an open-celled product. The crushed foam is reexpanded and finally cured. The foam may be filled for strengthening with a filler such as carbon black before or after the final cure.
