PVA –BP-17A & PVA-BP-26
Polyvinyl alcohol (PVA) is a synthetic polymer that belongs to the family of polyvinyl compounds. It is a water-soluble polymer that is created through the polymerization of vinyl acetate, followed by hydrolysis to remove the acetate groups. The resulting polymer is a white, odorless, and tasteless solid.
PVA has a high degree of hydrophilicity, meaning it readily absorbs and dissolves in water, forming a viscous solution. This property makes it useful in a wide range of applications, particularly in industries such as textiles, paper, adhesives, coatings, and pharmaceuticals.
PVA is used as a coating or film in packaging applications. It provides excellent barrier properties against gases and oils, making it suitable for food packaging, pharmaceutical packaging, and agricultural films.
PVA is a key component in various adhesive formulations. It is used in products like wood glue, paper adhesive, and fabric adhesives. PVA-based adhesives offer good bonding strength and water resistance.
PVA is used in the textile industry as a sizing agent. It improves the strength and wrinkle resistance of fabrics, making them easier to handle during processing and enhancing their overall quality.
PVA is used in paper coatings to improve the surface smoothness, printability, and strength of paper products. It enhances ink absorption and reduces ink bleeding, resulting in high-quality prints.
PVA is used as an additive in cement-based products, such as tile adhesives and mortars. It improves the adhesion, workability, and flexibility of these materials.
PVA is used in cosmetic and personal care products, including hair sprays, gels, and lotions. It provides a film-forming effect, which helps in holding hairstyles and improving the product’s performance.
PVA is utilized in water treatment processes to aid in the flocculation and sedimentation of impurities. It helps to remove suspended particles and improve the clarity of water.
