TH36323A - High absorbency polymer foam material - Google Patents

Abstract

The disclosed DC60 (09/06/42) is a polymer foam structure suitable for the absorption and retention of bodily fluids such as urine, menstrual blood, and similar fluids. This fluid retention structure is a highly absorbent, collapsible polymer foam material. The collapsible foam, when in contact with aqueous fluids, can absorb and expand these fluids even when resisted by pronounced hydrostatic pressure. These absorbent polymer foams consist of interconnected open cells. On the one hand, the foam can absorb at least approximately 25 g/g against a hydrostatic pressure of 50 cm. On the other hand, the foam of this invention will have an absorption height when vertically suspended at 90% of at least approximately 60 cm. The disclosed is a polymer foam structure suitable for the absorption and retention of bodily fluids such as urine, menstrual blood, and similar fluids. This fluid retention structure is a highly absorbent, collapsible polymer foam material. The collapsible foam, when in contact with aqueous fluids, can absorb and expand these fluids.

Claims (1)

1. A collapsible polymer foam structure with interconnected open cells which, when in contact with an aqueous fluid, can expand and absorb the fluid. The polymer foam structure has a minimum vertical absorption capacity of approximately 25 g/g at a hydrostatic pressure of 50 cm.
