Abstract
ESPUMA EN BLOQUE DE POLIURETANO, FLEXIBLE, SUSTANCIALMENTE HINCHADO EN AGUA, A BASE DE ISOCIANATOS DE METILENDIFENILO, QUE TIENEN UNA DENSIDAD EN EL INTERVALO DE 15-45 KG/M3. TALES ESPUMAS SE PUEDEN OBTENER POR UN PROCESO QUE NO USA PRACTICAMENTE AGENTES DE HINCHAMIENTO HIDROCARBONADOS, QUE CONSISTE EN LA REACCION DE ISOCIANATOS DE METILENDIFENILO CON AGUA Y UNO O MAS COMPUESTOS REACTIVOS DE ISOCIANATO ELEGIDOS DE POLIOLES Y POLIAMINAS CON UNA FUNCIONALIDAD DE 2-4 Y UN PESO EQUIVALENTE MEDIO DE 750-5000, MIENTRAS QUE EL INDICE DE ISOCIANATO OSCILA DE 10-60, Y LA RELACION EN PESO DE COMPUESTO(S) REACTIVO(S) DE ISOCIANATO A AGUA ES MENOR QUE 20.
