Abstract
Se describe un procedimiento para la produccion de materiales de espuma a partir de plásticos reactivos de dos componentes, utilizando dioxido de carbono como agente de expansion, mezclando al menos uno de los componentes reactivos con dioxido de carbono bajo presion, mezclando los componentes, al menos uno de los cuales contiene dioxido de carbono bajo presion, expandiendo la mezcla reactiva que contiene dioxido de carbono obtenida por mezclado, y endureciéndola, en el que la expansion tiene lugar de manera subita con la produccion de altas velocidades de corte. Con preferencia, la velocidad de flujo de la mezcla de reaccion se reduce tras la expansion.
