The Mepilex has a three-layer structure composed of a microporous/uniform polyester thermoset film and perforated adhesive silicones. Because of the layered and perforated structure, mechanical tests produced unreliable measurements, where reliable stress/strain results that represent physical behavior could not be determined.
