Abstract
Nuevo procedimiento para la obtención de bloques continuos de poliuretano expandido, que se caracteriza porque en sustitución de las habituales bandas de papel separador de la espuma y las paredes del dispositivo moldeador se han provisto láminas metálicas de superficie especular que permiten el fácil desprendimiento del material espumado, con la ventaja, además de que se dota de mayor uniformidad a sus capas externas y, como consecuencia, los desperdicios se reducen al mínimo.
