3M Tegaderm Foam Adhesive Dressing Overall Size: 4" x 4-1/2" Pad Size: 2-1/2" x 3" 3M Tegaderm Foam Adhesive Dressing is a highly absorbent, breathable wound dressing that is constructed from a conformable polyurethane foam pad and an additional absorbent nonwoven layer with a border of transparent adhesive film impermeable to liquids, bacteria and viruses. Heavily draining wounds often result in skin maceration, frequent dressing changes and patient discomfort. Tegaderm foam adhesive dressing provides total fluid management by a combination of fast wicking, high absorbency and breathability and uses an innovative moist skin adhesive technology. The unique spoke-shaped delivery system allows fast, easy application for wounds over body contours.
