Abstract

La presente invención se refiere a un procedimiento de producción de un cuerpo de espuma de PUR/PIR, que comprende las etapas de proporcionar un molde adaptado para aplicar una subpresión al interior del molde; introducir una mezcla de reacción que comprende un componente A reactivo con isocianatos y un isocianato B en el molde, y aplicar una subpresión al interior del molde, de modo que la subpresión actúe sobre la mezcla de reacción introducida. La subpresión es aplicada al interior del molde no más tarde de que la mezcla de reacción haya empezado a solidificarse en el molde y el índice de isocianato de la mezcla de reacción es = 300.
