What is Alginate Wound Dressing?
Made up of soft non-woven fibers that come from seaweed, alginates absorb wound drainage and convert it into a gel-like covering over the wound, creating a moist wound environment. A wide range of alginate products are available for a variety of wounds. Additives such as calcium and silver can be added to the dressing fibers to continue to promote a healing environment.
