Abstract

SE DESCRIBE UNA LAMINA PLURICAPA DE POLIOLEFINAS, OBTENIDA POR COEXTRUSION, SELLABLE POR AMBAS CARAS, TRANSPARENTE, CUYA CAPA BASICA SE COMPONE ESENCIALMENTE DE UNA RESINA MODIFICADA DE POLIMERO DE PROPILENO Y CUYAS CAPAS EXTERIORES SE COMPONEN ESENCIALMENTE DE POLIMEROS SELLABLES DE OLEFINAS. LA LAMINA PLURICAPA POSEE A 120 C UNA CONTRACCION LONGITUDINAL MAYOR AL 7% Y UNA CONTRACCION TRANSVERSAL MAYOR AL 5%, ESTANDO COMPUESTA ESENCIALMENTE LA CAPA BASICA DE LA LAMINA PLURICAPA POR UN POLIMERO DE PROPILENO, DEGRADADO PEROXIDICAMENTE, CUYO FACTOR DE DEGRADACION A ES EL ORDEN DE 3 A 10, Y CONTIENE 5 A 25% EN PESO DE UNA RESINA DE HIDROCARBUROS. LAS CAPAS EXTERNAS DE LA LAMINA PLURICAPA SE COMPONEN ESENCIALMENTE DE UN COPOLIMERO ESTADISTICO DE ETILENOPROPILENO QUE POSEE UN CONTENIDO DE ETILENO DEL 2 AL 8% EN PESO, PREFERENTEMENTE DEL 3 AL 7% EN PESO, UN FACTOR DE REPARTO V SUB F MAYOR A 8 Y UNA TEMPERATURA DE TERMOOXIDACION T SUB OX SUPERIOR A 230 C. LA LAMINA POSEE UN BRILLO SUPERFICIAL (ANGULO DE MEDIDA 20 ) SUPERIOR A 100 Y UN ENTURBIAMIENTO (MEDIDO EN 4 CAPAS DE ESPESOR) MENOR DEL 22%.
