Abstract

La presente invencion se refiere a un procedimiento para la produccion de una espuma de poliuretano rígida, en el que se usa un poliisocianato que contiene un anillo de benceno como isocianto orgánico y se usa un poliéter poliol y/o poliéster poliol como poliol, caracterizado porque, se usa un hidrocarburo como agente de expansion y se usa un compuesto que tiene un grupo hidrofobo y un grupo hidroxilo en la molécula como agente emulsionante. Preferiblemente, el agente de expansion es un hidrocarburo seleccionado entre el grupo formado por ciclopentano, n-pentano e isopentano.
