Abstract

QUE COMPRENDE: A) UNA PELICULA ELASTOMERICA CON LONGITUD NO DERIVADA, LONGITUD EXTENDIDA DE 160% DE LA LONGITUD NO DERIVADA Y UNA LONGITUD DE RECUPERACION INMEDIATA DE POR LO MENOS 55% DE LA LONGITUD NO DERIVADA DESPUES DE UN CICLO DE ESTIRAMIENTO RESULTANDO LA LONGITUD EXTENDIDA, TIENE ADEMAS UNA VELOCIDAD DE TRANSMISION DE VAPOR DE AGUA DE 300 g/m2/24 h; E INCLUYE: i) UN POLIMERO CON BASE DE ETILENO CATALIZADO CON METALOCENO CON UNA DENSIDAD QUE VA DESDE 0,850 g/cc A 0,899 g/cc, Y SE SELECCIONA DE COPOLIMEROS DE ETILENO/BUTILENO, ETILENO/HEXENO, ETILENO/OCTENO Y COMBINACIONES DE ESTOS, Y ii) POR LO MENOS 30% POR PESO DE CARBONATO DE CALCIO COMO MATERIAL DE RELLENO QUE POSEE UN TAMANO DE PARTICULA ENTRE 0,5 Y 8 MICRAS, QUE CONTRIBUYE A LA FORMACION DE POROS; Y B) POR LO MENOS UNA CAPA DE SOPORTE UNIDA A LA CAPA DE LA PELICULA MENCIONADA. Y UN METODO QUE COMPRENDE: 1) PROPORCIONAR UNA RESINA POLIMERICA QUE INCLUYE UN POLIMERO CON BASE DE ETILENO CATALIZADO CON METALOCENO; 2) AGREGAR EL MATERIAL DE RELLENO PARA FORMAR UNA RESINA RELLENA; 3) FUNDIR UNA PELICULA DE LA RESINA RELLENA HASTA UNA PRIMERA LONGITUD; 4) ESTIRAR DICHA PELICULA EN DIRECCION A LA MAQUINA HASTA FORMAR UNA PELICULA MICROPOROSA CON UNA SEGUNDA LONGITUD; Y 5) UNIR UNA CAPA DE SOPORTE A LA PELICULA PARA FORMAR UN MATERIAL LAMINARWHAT IT INCLUDES: A) AN ELASTOMERIC FILM WITH NON-DERIVED LENGTH, EXTENDED LENGTH OF 160% OF NON-DERIVED LENGTH AND AN IMMEDIATE RECOVERY LENGTH OF AT LEAST 55% OF NON-DERIVED LENGTH AFTER A CYCLE OF EXTENDED LENGTH. , ALSO HAS A WATER VAPOR TRANSMISSION SPEED OF 300 g / m2 / 24 h; AND INCLUDES: i) A METHYLENE CATALYZED BASED ETHYLENE POLYMER WITH A DENSITY THAT GOES FROM 0.850 g / cc TO 0.899 g / cc, AND IS SELECTED FROM ETHYLENE / BUTYLENE, ETHYLENE / OCTENE AND COMBINE COPOLYMERS THESE, AND ii) AT LEAST 30% BY WEIGHT OF CALCIUM CARBONATE AS A FILLING MATERIAL THAT HAS A PARTICULAR SIZE BETWEEN 0.5 AND 8 MICRONS, WHICH CONTRIBUTES TO THE FORMATION OF PORES; AND B) AT LEAST ONE SUPPORT LAYER ATTACHED TO THE LAYER OF THE MENTIONED FILM. AND A METHOD THAT INCLUDES: 1) PROVIDING A POLYMERIC RESIN THAT INCLUDES A POLYMER BASED ON ETHYLENE CATALYZED WITH METALOCHENE; 2) ADD FILLING MATERIAL TO FORM A FILLED RESIN; 3) CAST A FILM OF THE FILLED RESIN UP TO A FIRST LENGTH; 4) STRETCH SUCH FILM IN THE DIRECTION OF THE MACHINE UNTIL FORMING A MICROPOROUS FILM WITH A SECOND LENGTH; AND 5) ATTACH A SUPPORT LAYER TO THE FILM TO FORM A LAMINAR MATERIAL
