Polyurethane Foam is used in Foam Dressings

Foam dressings, which are made of semipermeable polyurethane, contain foamed polymer solutions that have tiny, open cells that may store fluids. Other materials might be stacked between these cells. The thickness of the dressing affects how well they absorb substances. Since a foam dressing's contact area is nonadherent and nonlinting, it is simple to remove. To prevent germs and other pollutants from entering, the dressing's outer layer is frequently hydrophobic or waterproof. Foam dressings are available in a variety of sizes and forms, both with and without an adhesive border. A transparent film-based bacterial barrier is sometimes used to foam treatments as well.
