The sterile PolyMem nonadhesive dressing is lightweight and non-adherent for quick dressing changes. It's formulated with a starch co-polymer for moisture retention and includes glycerol to regulate hydration. PolyMem 5-inch x 5-inch wound dressing absorbs output from the wound to keep it clean. The nonadherence properties keep the wound bed protected. The pink dressing expands to conform to the wound, creating a protective cover.
