Abstract

Método para la producción de espumas de poliuretano nanoporosas, que incluye las etapas a) carga de un fundido de polímero formado de polímeros termoplásticos, con un agente propelente bajo una presión y a una temperatura en las cuales el agente propelente se encuentra en estado supercrítico, b) acondicionamiento de temperaturas de fundido de polímero cargado a una temperatura que está en el rango de 40 C por debajo a 40°C por encima de la temperatura de transición al vidrio, que puede ser determinada por medio de DSC según DIN-ISO 11357-2 a una rata de calentamiento de 20 K/min, del fundido de polímero no cargado, c) reducción de la presión del fundido de polímero cargado en la etapa a) y con acondicionamiento de temperatura en la etapa b) con una rata de reducción de presión en el rango de 15.000 a 2.000.000 MPa/sec. 10 2. Método según la reivindicación 1, caracterizado porque la carga y acondicionamiento de temperatura
