Polyvinyl alcohol (PVA) is a versatile polymer used in many industrial applications, from textiles to construction. In the textile industry, PVA is used to size fabrics, enhancing their strength and smoothness during production. PVA is also used in the production of biodegradable packaging films, offering a sustainable alternative to traditional plastic films. Additionally, PVA is incorporated into construction materials, such as cement and adhesives, to improve bonding and flexibility.
