Abstract

COMPOSICION DE POLIISOCIANATO QUE COMPRENDE: (A) 30 A 45% EN PESO DE DIISOCIANATOS DE DIFENILMETANO; (B) 28 A 67% EN PESO DE POLIMETILEN - POLIFENILEN - POLIISOCIANATOS QUE TIENEN MAS DE DOS GRUPOS ISOCIANATO LIBRES EN LA MOLECULA; Y (C) 3 A 27% EN PESO DE PREPOLIMERO A PARTIR DE DIISOCIANATO DE DIFENILMETANO Y UN COMPUESTO QUE CONTIENE, AL MENOS, DOS GRUPOS REACTIVOS ISOCIANATO Y CON UN PESO MOLECULAR POR DEBAJO DE 1000; SE CALCULA EL % EN PESO SOBRE LA CANTIDAD TOTAL DE (A), (B) Y (C) PRESENTES EN LA COMPOSICION, SIENDO EL NUMERO MEDIO DE FUNCIONALIDAD ISOCIANATO DE LA COMPOSICION DE, AL MENOS, 2.3. LAS COMPOSICIONES MUESTRAN UNA MISCIBILIDAD MEJORADA CON POLIOLES PARA ESPUMAS RIGIDAS, LO QUE DA LUGAR A VENTAJAS EN EL PROCESADO. LAS ESPUMAS HECHAS CON ESTAS COMPOSICIONES PRESENTAN UN TAMAÑO DE CELDILLA MAS PEQUEÑO Y UNA CONDUCTIVIDAD TERMICA MAS BAJA.
