Abstract

PREPARACION DE HOJAS DE ESPUMA DE PLASTICO RIGIDO FLEXIBILIZADAS, PARA AISLAMIENTO A BAJA TEMPERATURA Y CRIOGENICO. SE COMPRIMEN MECANICAMENTE ESPUMAS TERMOPLASTICAS DE CELDAS CERRADAS RECIENTEMENTE EXPANDIDAS. ASI, UNA HOJA DE ESPUMA EXTRUIDA QUE TIENE UN PESO ESPECIFICO DE 20-100 KG/M , UN TAMAÑO Y AXIAL DE CELDA DE 0,05 A 1,00 MM Y UNA RESISTENCIA A LA COMPRESION EN LA DIRECCION DEL EJE Y DE AL MENOS 1,8 KG/CM , SE FLEXIBILIZA CON 0,25 A 240 HORAS DE EXPANSION, PARA DAR UNA ESPUMA FLEXIBILIZADA CON ALARGAMIENTO, APTITUD PARA TRABAJO, RESISTENCIA AL AGRIETAMIENTO Y PROPIEDADES DE BARRERA AL VAPOR DE AGUA MEJORADOS.
