The tailored micro-cellular matrix of INOAC medical foam is an ideal controlled delivery structure for a wide range of active agents. Our foams tear resistance allows it to be fabricated into almost any configuration by shaping, stitching, cementing, and other techniques. INOAC medical foam is a thin membrane of polyurethane encapsulating a network of open cells. INOAC’s reticulation technology removes the membranes of the foam allowing for a completely open-pore foam with a skeletal structure through which fluids and gasses easily pass. Pore size can be precisely governed for permeability control and design flexibility, as well as an aesthetic appearance whenever needed.
