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, assisting in a faster and less painful dressing change.
