Polyvinyl alcohol (PVA) is an essential polymer with significant applications in various industries. It is used in the textile industry as a sizing agent to improve fabric durability and strength. In construction, PVA is added to adhesives and coatings to enhance their performance, providing superior adhesion and flexibility. PVA also plays a critical role in the production of biodegradable films and coatings, making it an environmentally friendly choice for packaging and protective coatings.
