Polyvinyl alcohol (PVA) is a versatile polymer that finds numerous applications
due to its unique properties. PVA is a water-soluble synthetic polymer that can be produced in various
grades with different molecular weights and degrees of hydrolysis. PVA
098-15 refers to a specific grade of PVA with a particular molecular weight and hydrolysis level.
Here are some common applications of PVA, including its potential uses:
1. Adhesives: PVA is widely used as a primary component in the formulation of adhesives. It forms a
strong bond with various surfaces, including paper, cardboard, wood, and fabrics. PVA-based adhesives are
used in woodworking, packaging, bookbinding, and paper industries.
2. Packaging: PVA films and coatings are used for packaging applications.
These films offer excellent water resistance and barrier properties, making them suitable for packaging
products such as detergents, agrochemicals, and food items.
3. Textile Industry: PVA fibers are used in the textile industry to produce
fabrics with desirable properties, such as high strength, durability, and resistance to chemicals. PVA
fibers are also used in non-woven textiles, geotextiles, and in the manufacturing of filters and screens.
4. Paper Industry: PVA is used as a coating agent for paper and paperboard products. It improves the
surface strength, printability, and water resistance of papers. PVA is also employed as a binder in the
production of specialty papers, such as carbonless copy paper and inkjet photo papers.
5. Construction Materials: PVA is used in the construction industry for various applications. It is used
as an additive in cement and mortar formulations to enhance workability and adhesion properties. PVA
fibers are also used in concrete to improve its strength, crack resistance, and durability.
6. Pharmaceuticals: PVA is used in the pharmaceutical industry for various purposes. It is used as a
binder in tablet formulations to hold the ingredients together. PVA-based films are used for the
controlled release of drugs. PVA is also used as a suspending agent and viscosity modifier in liquid
pharmaceutical preparations.
7. Personal Care Products: PVA is found in various personal care products, including cosmetics, lotions,
and hair sprays. It acts as a film-forming agent, providing a protective barrier on the skin or hair. PVA
is also used in contact lens solutions and artificial tears due to its biocompatibility and
water-retaining properties.
8. Emulsifiers and Dispersants: PVA can act as an emulsifier or dispersant in various applications. It
helps in stabilizing emulsions and suspensions, improving their shelf life and preventing phase
separation.
