PVA’s industrial applications span diverse sectors. In textiles, it serves as a warp sizing agent, increasing yarn tensile strength by 30-50% during weaving, with easy removal via washing. The paper industry uses PVA as a surface sizing agent to improve printability and water resistance in packaging papers, while in adhesives, it bonds wood, paper, and cardboard with strong, quick-drying properties. Construction benefits from PVA powder as a cement admixture, enhancing mortar flexibility and crack resistance. In pharmaceuticals, PVA acts as a tablet binder and ophthalmic solution base, leveraging its biocompatibility. Additionally, PVA is used in 3D printing as a water-soluble support material, in cosmetics as a thickener, and in electronics for protective coatings on circuit boards.
