Each layer of foam adhesive helps improve the performance of the dressing.
The core of the dressing is a layer of absorbent polyurethane foam that absorbs wound exudate vertically into the dressing.
The absorbent pad retains the exudate within the dressing, preventing the exudate from re-entering the wound and impregnating the peri-wound and surrounding skin.
The polyurethane film provides an effective barrier function and is waterproof while allowing the transpiration of exudates, which contributes to the overall fluid handling capacity of the dressing.
