1.description. Allevyn consists of a layer of soft, hydrophilic polyurethane foam, about six millimetres thick, bonded to a pink semipermeable polyurethane film. Although this film is permeable to moisture vapour, it provides an effective barrier to water or wound exudate and also prevents the passage of microorganisms through the back of the dressing.
