"Maxorb Extra AG Alginate Dressing, 12"" Rope. Latex-Free Maxorb Extra Ag is a highly absorbent, non-woven pad composed of a high G (guluronic acid) calcium alginate, carboxymethylcellulose (CMC) and ionic silver. Exposure to wound exudate dissolves the silver and stimulates the release of silver ions. As more fluid is absorbed over time, more silver ions are released, creating a controlled-release antimicrobial effect. The silver ions protect from a broad spectrum of microorganisms, including MRSA and VRE. Plus Maxorb Extra Ag releases silver extremely small amounts that do not damage healthy tissue. Maxorb Extra Ag is biocompatible, non-irritating, non-sensitizing and will not harm new granulation tissue. "
