Polyvinyl alcohol (PVA) is a synthetic polymer known for its high water solubility, adhesion, and film-forming capabilities. These properties make it ideal for a wide range of applications, from adhesives to coatings. In the textile industry, PVA is used as a finishing agent that improves fabric strength and provides resistance to abrasion. It is also used in construction for making adhesives and coatings due to its excellent performance in terms of durability and moisture resistance. Additionally, PVA is commonly used in cosmetic formulations due to its ability to form a smooth, flexible film on the skin.
