PolyMem Dressings consist of a polyurethane membrane matrix on a semipermeable thin-film backing. Unlike any other dressing, the hydrophilic membrane contains a cleanser, a moisturizer and a super-absorbent starch co-polymer. This unique design and patented formulation eliminates the need for manual debridement and cleaning during dressing changes, reducing patient discomfort and the time and cost of dressing changes. PolyMem facilitates the healing process by promoting the concentration of the body’s naturally produced growth factors, nutrients and regenerated cells in the wound bed.
