Properties and Viscosity of CMC

Polyvinyl alcohol (PVA) is a widely used polymer that finds applications as a glue or adhesive in various industries. Here are some key facts about Polyvinyl Alcohol as glue:

1. Water-Soluble:

PVA is water-soluble, which means it can be easily dissolved in water to form a viscous solution. This property makes PVA glue convenient to use and allows for easy cleanup with water.

2. Non-Toxic and Safe:

PVA glue is generally non-toxic and safe for use in various applications, including arts and crafts, woodworking, and paper projects. It is often preferred for use in schools, households, and DIY projects due to its safety profile.

3. Versatile Adhesive:

PVA glue exhibits excellent adhesion to a wide range of substrates, including paper, wood, fabric, cardboard, and porous materials. It is commonly used for bonding paper, cardboard, and wood in crafts, woodworking, bookbinding, and packaging applications.

4. Dries Clear:

PVA glue dries to a transparent or translucent finish, leaving no visible residue or discoloration on the bonded surface. This makes it ideal for applications where aesthetics are important, such as paper crafts, collage, and decorative projects.

5. Strong Bond:

When properly applied and allowed to dry, PVA glue forms a strong and durable bond between substrates. It provides good initial tack and adhesion strength, as well as excellent bond strength over time.

6. Modifiable Properties:

The properties of PVA glue can be modified by adjusting factors such as concentration, viscosity, and additives. This allows for customization of the glue to suit specific application requirements, such as desired bond strength, drying time, and flexibility.

7. Water-Based and Eco-Friendly:

PVA glue is water-based and does not contain volatile organic compounds (VOCs) or harmful chemicals, making it environmentally friendly. It is biodegradable and can be safely disposed of in most municipal waste systems.

8. Applications:

PVA glue is used in a wide range of applications, including:

  • Arts and crafts: collage, paper mache, scrapbooking
  • Woodworking: joinery, veneering, laminating
  • Bookbinding: binding book pages and covers
  • Packaging: sealing cardboard boxes, cartons, and envelopes
  • Textiles: bonding fabric layers in sewing and garment manufacturing

9. Variants and Formulations:

PVA glue is available in various formulations, including liquid, gel, and solid forms. It can also be modified with additives such as plasticizers, thickeners, and cross-linking agents to enhance specific properties or performance characteristics.


Polyvinyl Alcohol (PVA) glue is a versatile adhesive with a wide range of applications in arts and crafts, woodworking, packaging, textiles, and other industries. Its water-soluble nature, non-toxicity, versatility, and strong bonding properties make it a popular choice for bonding various substrates in diverse applications. Whether used in schools, households, or industrial settings, PVA glue provides a reliable and effective solution for bonding and assembly needs.
