Polyvinyl alcohol (PVA) is a synthetic polymer that has various advantages and
applications across different industries. PVA 088-20 is a specific grade of
PVA known for its high molecular weight and excellent film-forming properties. Here are some of the
advantages and applications of PVA 088-20:
Advantages of PVA 088-20:
1. Water Solubility: PVA 088-20 exhibits excellent water solubility, making it easy to dissolve in water
and form clear solutions. This property is particularly useful in applications where a water-soluble film
or coating is required.
2. Film-Forming Capability: PVA 088-20 has a high molecular weight, which enables it to form strong and
flexible films. These films have good barrier properties, such as resistance to gas permeation, making
them suitable for packaging applications.
3. Adhesive Properties: PVA 088-20 can act as an adhesive due to its ability to form strong bonds with
various substrates. It is commonly used as a glue for paper, wood, and other porous materials.
4. Biodegradability: PVA is a biodegradable polymer, and PVA 088-20 follows the
same property. It can be broken down by microorganisms in the environment, reducing its impact on waste
accumulation.
Applications of PVA 088-20:
1. Textile Industry: PVA 088-20 is used in textile sizing and finishing processes to provide stiffness and
improve the handling properties of yarns. It forms a temporary protective coating on fibers, aiding in
weaving and preventing fiber breakage.
2. Paper Industry: PVA 088-20 is utilized as a surface sizing agent for paper and paperboard production.
It improves the surface strength and printability of the paper, resulting in better ink absorption and
reduced ink feathering.
3. Packaging: PVA 088-20 is employed in the manufacture of water-soluble packaging films and pouches.
These films are used for single-use packaging of detergents, agrochemicals, dyes, and other water-soluble
products, reducing packaging waste.
4. Adhesives: PVA 088-20 is a key component in the formulation of water-based adhesives. It is widely
used in applications such as woodworking, paperboard laminating, and general-purpose bonding, providing
good adhesion and easy clean-up.
5. Personal Care Products: PVA 088-20 finds application in the cosmetics and personal care industry. It
is used in the formulation of hair sprays, gels, and mousses, providing excellent film-forming properties
without causing excessive stiffness or flaking.
6. Medical and Pharmaceutical: PVA 088-20 is used in the production of soluble capsules and tablet
coatings for controlled release of pharmaceutical ingredients. It also finds applications in wound
dressings and as a component in eye drops and artificial tears.
