Abstract

METODO PARA PREPARAR UNA ESPUMA DE POLIOLEFINA. CONSISTE EN: A) MEZCLAR EN FUSION, A PRESION Y A TEMPERATURA ENTRE 160 Y 230JC, UNA POLIOLEFINA LINEAL JUNTO CON UN AGENTE DE SOPLADO Y UN AGENTE DE RETICULACION EN UNA CANTIDAD DE 0,01 A 2,0 PARTES POR CIEN, PARA FORMAR UNA MEZCLA CAPAZ DE FLUIR QUE TIENE UN INDICE DE FUSION SUPERIOR A 0,1; Y B) EXTRUIR DICHA MEZCLA A TRAVES DE UNA MATRIZ HASTA UNA ZONA DE PRESION MENOR Y A UNA TEMPERATURA COMPRENDIDA ENTRE 100 Y 140JC, Y ACTIVAR EL AGENTE DE SOPLADO PARA EXPANDIR UNA POLIOLEFINA LINEAL Y OBTENER LA ESPUMA LIGERAMENTE RETICULADA. TIENE APLICACION EN LA OBTENCION DE ESPUMAS.
