Three-dimensional networks of cross-linked hydrophilic polymers that are insoluble in water and interact with aqueous solutions by swelling. They are highly conformable and permeable and can absorb varying amounts of drainage, depending on their composition. Non-adhesive against the wound for easy removal. Indicated for partial- and full-thickness wounds, wounds with necrosis, minor burns and radiation tissue damage. Available in various sizes, with and without adhesive borders.
