Ionized polyvinyl alcohol sponge

A new type of medical non-fiber sponge formed by introducing sodium polyacrylate side chains into PVA macromolecules is called ionized polyvinyl alcohol sponge. It has good biocompatibility and stable chemical properties, and has excellent hydrophilicity, liquid absorption and Blood-sucking performance. i-PVA sponge can be effectively used in medical operations such as microsurgery and eye surgery that strictly require no fiber shedding, especially in cataract and intraocular lens replacement surgery. The following grades are often used in the production process: PVA 0599, 1099, 2499, 2088.
