Abstract
Los materiales de espuma absorbente son capaces de adquirir y distrbuir los fluidos corporales descargados como por ejemplo, la orina. Estas espyumasabsorbentes combinan presiones de absorción capilar relativamente altas y propiedades de capacidad por peso que les permiten adquirir fluido, con o sinayuda de la gravedad. Estas espumas absorbentes también entregan eficientemente este fluido a los materiales de almacenamiento con mayor presión de absorción,incluyendo a los componentes dealmacenamiento de fluido absorbente basados en la espuma, sin hundirse. Estas espumas absorbentes se preparan polimerizandoemulsiones de fase interna alta (HIPEs). La estructura de espuma polimérica tiene: A) una capacidad después de la desorción a 30 cm. de menos de 10% de lacapacidad de espuma absorbente libre; B) una presión capilar de absorción de desde 3 a 20 cm; C) una presión de desorción capilar desde 8 a 25 cm; D) unaresistencia a la compresión de deflexión de desde 5 a 85% cuando es medida bajo una presión de confinamiento de 0,74 psi; y E) una capacidad libreabsorbente de desde 12 a 125 g/g.
