Polyvinyl alcohol (PVA) is a versatile polymer that has a wide range of applications in various industries. Some of the major or common uses of PVA include:
- Adhesives: PVA is commonly used as a primary component in white glue, wood glue, and other types of adhesives. It is a popular choice for woodworking, paper crafting, and other DIY projects.
- Packaging: PVA is used as a coating agent in food packaging materials, such as plastic films and containers, to improve their barrier properties and prolong the shelf life of the packaged products.
- Textiles: PVA is used in textile manufacturing to create fibers that are resistant to heat and chemicals, and to provide strength and flexibility to fabrics.
- Paper: PVA is used as a coating agent in paper production to enhance the paper’s strength, printability, and durability.
- Construction materials: PVA is used in construction materials, such as cement and mortar, to improve their adhesion, water resistance, and workability.
- Medical applications: PVA is used in various medical applications, such as drug delivery systems, wound dressings, and artificial blood vessels, due to its biocompatibility and non-toxicity.
- Personal care products: PVA is used in personal care products, such as hair styling gels and lotions, to provide viscosity, adhesion, and film-forming properties.
