N-TERFACE® Interpositional Surfacing Material is a unique, high density polyethylene sheeting. When used as the primary wound contact layer, the N-TERFACE® Material prevents wound disruption due to the adherence by absorbent dressings, decreases wound shear and provides a ?Window on the Wound? for visualization or cleansing and/or application of creams or ointments directly to the wound surface. Outer dressings are removed atraumatically from the N-TERFACE® wound contact layer. To help protect fragile epithelium, the N-TERFACE® Material may be left in place between absorbent dressing changes.
