    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.

    摘要： The invention concerns a high-pressure mixing head preferably for polyurethane reactive plastics, the mixing head comprising a mixing chamber and a settling chamber, and the settling chamber having a substantially rectangular cross-section with an axial ratio of between 10 and 100. The high-pressure mixing head can be used in particular to produce filler-containing polyurethanes, the fillers being centrifuged laterally against the reactive mixture which emerges in the form of a curtain from the settling chamber.
