Biatain Non Adhesive Foam Biatain foam, with its unique 3DFit TechnologyTM, conforms to the wound bed up to 2cm to fill the gap and prevent exudate pooling for optimal wound healing. This saves on time and money by reducing the need of fillers in wounds less than 2cm deep. Biatain Non-Adhesive can be used on a wide range of exuding wounds where the periwound skin is extra fragile and no adhesion is preferred.
