摘要：
The present invention relates to a method for producing a polyurethane foam, wherein the propellant used is present in the supercritical or near-critical state. A reaction mixture is introduced into a closed mold, wherein the closed mold is set up such that the inner volume thereof and/or the pressure in the interior thereof can be changed by external effects after introducing the mixture. By selecting the surfactant, microemulsions of the propellant can be obtained in the polyol phase. The invention further relates to a nanocellular polyurethane foam that can be obtained by means of the method according to the invention.
摘要（中）：
本发明涉及生产聚氨酯泡沫塑料的方法，其中使用的发泡剂处于超临界或接近临界状态。 将反应混合物引入封闭的模具中，其中封闭的模具被设置为使得其内部容积和/或其内部主要的压力可以在通过外部影响引入混合物之后改变。 通过选择表面活性剂，可以获得发泡剂在多元醇相中的微乳液。 本发明的另一主题是可通过根据本发明的方法获得的纳米蜂窝状聚氨酯泡沫。
