Abstract

UNA ESPUMA DE LATEX POLIMERO ABSORBENTE DE AGUA ES PRODUCIDA MEDIANTE UN PROCESO DE COMBINACION DE UN PRODUCTO DE ESPUMA DE LATEX POLIMERO CON UN POLIMERO ABSORBENTE DE AGUA; TAL MEZCLA ES SECADA PARA FORMAR UN LATEX POLIMERO CAPAZ DE CONVERTIRSE EN ESPUMA CONTENIENDO UN POLIMERO ABSORVENTE DE AGUA, LO CUAL SE EXPONE EN ESTA INVENCION. LAS ESPUMAS DE LATEX PRODUCIDAS MEDIANTE ESTE PROCESO HAN SIDO MUY USADAS, POR EJEMPLO, DENTRO DE PAÑALES, EN SERVILLETAS DE SANITARIOS, MATERIALES DE EMPAQUETAMIENTO Y SIMILARES. EN PARTICULAR, EL USO DE POLIMEROS ABSORVENTES DE AGUA CON PARTICULAS DE TAMAÑO MENOR A 30 MICRONES SE UTILIZAN PARA PRODUCIR PARTICULARMENTE ESPUMAS EFECTIVAS DE LATEX ABSORVENTE. ADEMAS, UNA ESPUMA DE LATEX POLIMERO ABSORVENTE DE AGUA, PRODUCIDA MEDIANTE EL PROCESO DE COMBINACION DE UN PRODUCTO DE ESPUMA DE LATEX POLIMERO ASI COMO UN POLIMERO ABSORVENTE DE AGUA COMBINADO A ESTA MEZCLA QUE SE COMUNICA Y SE SECA PARA FORMAR UN POLIMERO LATEX ESPUMOSO QUE CONTIENE A AMBOS ELEMENTOS.LAS ESPUMAS DE LATEX PRODUCIDAS POR ESTE PROCESO SON DE GRAN USO, POR EJEMPLO, EN HERIDAS O EN PREPARADOS QUIRURGICOS.
