Polyvinyl alcohol (PVA) is a synthetic polymer made from the polymerization of vinyl acetate. It is a water-soluble substance known for its film-forming, emulsifying, and adhesive properties. PVA is commonly used in various applications, including packaging, textiles, and paper products. In addition to its industrial uses, PVA is also found in some medical and cosmetic products due to its biocompatibility. It can be used in hydrogels for drug delivery and wound dressings, as well as in adhesives and coatings that require a strong bond and flexibility.
