PVA 098-04 Applications
Polyvinyl Alcohol (PVA) is a synthetic polymer that has a wide range
of
applications due to its unique properties. PVA 098-04 refers
to a specific
grade or formulation of PVA.
1. Adhesives: PVA is widely used as a glue or adhesive in various industries. It forms a
strong bond with
materials such as paper, wood, fabric, and leather. PVA adhesives are commonly used in
woodworking,
packaging, bookbinding, and arts and crafts.
2. Textile Industry: PVA is used in the textile industry for sizing and finishing fabrics. It
improves
the weaving process by providing temporary stiffness to yarns, enhancing their strength and
preventing
yarn breakage. PVA is also used as a component in textile coatings and as a binder in
non-woven fabrics.
3. Papermaking: PVA is employed in the paper industry as a coating agent to improve the
surface
properties of paper, including gloss, smoothness, and ink absorption. It can also be used as
a retention
aid to enhance the retention of fine particles during the papermaking process.
4. Packaging: PVA films and coatings are used in the packaging
industry due
to their excellent barrier properties against moisture and gases. PVA films can be used as
water-soluble
packaging materials for products like detergent pods or agricultural chemicals.
5. Pharmaceuticals: PVA is utilized in pharmaceutical applications, particularly for the
formulation of
oral solid dosage forms. It can be used as a binder in tablet formulations, as a
film-forming agent for
drug coatings, or as a component in controlled-release systems.
6. Emulsifiers and Dispersing Agents: PVA can act as an emulsifier or dispersing agent in
various
industries, including paints, coatings, and personal care products. It helps to stabilize
emulsions and
suspensions, preventing phase separation.
7. 3D Printing: PVA is sometimes used as a support material in 3D printing processes that
utilize dual
extrusion printers. It can be printed alongside a primary material and later dissolved in
water to remove
the support structures.
