(EN) HIGH PERFORMANCE SUPERABSORBENT MATERIAL AND ABSORBENT DEVICES CONTAINING THE SAME
(FR) MATERIAU ULTRA-ABSORBANT A HAUTE EFFICACITE ET DISPOSITIFS ABSORBANTS CONTENANT CELUI-CI
Abstract
(EN)
A high performance absorbent particulate composition and a method of preparation in which a non-colloidal solid filler core is substantially encapsulated within a layer of hydrogel forming polymer is disclosed. Also disclosed are absorbent devices using the high performance absorbent particulate composition and methods of making these devices.
(FR)
On décrit une composition particulaire absorbante à haute efficacité et un procédé de préparation dans lequel un noyau solide constitué d'une charge non colloïdale est sensiblement encapsulé dans une couche de polymère formant un hydrogel. On décrit également des dispositifs absorbants utilisant la composition particulaire absorbante à haute efficacité et des procédés pour réaliser ces dispositifs.
