Abstract

METODO DE PREPARACION DE UN MATERIAL ALVEOLAR MICROCELULAR RETICULADO HECHO DE POLIETILENO DE BAJA DENSIDAD O DE UNA COMBINACION DE POLIETILENO DE BAJA DENSIDAD CON UNO O VARIOS OTROS POLIMEROS. LA MEZCLA DE POLIETILENO, AGENTE DE SOPLADO, INICIADOR DE RETICULACION, POLIMEROS Y ADITIVOS SE TRANSFORMA EN MATERIAL EN FORMA DE HOJA, QUE SE PRECALIENTA Y CALIENTA SEGUIDAMENTE. EL AGENTE DE RETICULACION TIENE UN PERIODO DE SEMI-DESCOMPOSICION DE 10 HORAS ENTRE 80 Y 100JC. PREFERENTEMENTE, EL AGENTE DE RETICULACION SE UTILIZA CON UN AGENTE DE CO-RETICULACION COMO CIANURO DE TRIALILO.
