    摘要： The invention relates to a process for continuous production of polyurethane slab-stock foam using carbon dioxide (40), dissolved physically under pressure, as the foaming agent. Before mixing the constituents polyhydric alcohol (36) and isocyanate (35), said carbon dioxide (40) is dissolved in the polyhydric alcohol constituent, and air or nitrogen (39) is dissolved in the isocyanate constituent. Both constituents are delivered to a mixing chamber (3) in which there is a pressure 70 to 150 % of the solution pressure of the CO2 in the polyhydric alcohol constituent. The isocyanate constituent is delivered at a pressure of at least 30 bar to the mixing chamber, and by dropping to the mixing chamber pressure is sprayed into said mixing chamber. Air or nitrogen amounting to 1 g per kg of CO2 is dissolved in the isocyanate constituent, and the mixture drops to atmospheric pressure on leaving the mixing chamber.

    摘要： A process is described for producing foam materials from two-component reactive plastics using carbon dioxide as blowing agent by mixing at least one of the reactive components with carbon dioxide under pressure, mixing the components, at least one of which contains carbon dioxide under pressure, expanding the reactive mixture containing carbon dioxide obtained by mixing, and hardening, wherein the expansion takes place suddenly with the production of high rates of shear. Preferably the rate of flow of the reaction mixture is reduced after expansion.
