Polyvinyl alcohol (PVA) is a synthetic polymer known for its solubility in water and strong film-forming abilities. It plays a crucial role in the textile industry by acting as a sizing agent to enhance the strength and durability of fabric during production. PVA also serves as a key component in the manufacturing of water-soluble films, providing eco-friendly packaging options. In the pharmaceutical and cosmetics industries, PVA is used for its adhesive properties in tablets and personal care products.
