What are the Best Industrial Uses for PVA Glue?

Originally discovered in 1912, PVA glue is one of the most universal and versatile adhesives on the market. Not only are there countless industrial PVA glue uses, but the relatively stable nature of this compound makes it ideally suited for a number of requirements. Comprised of a chemical known as polyvinyl acetate (PVA), this glue does not release any flammable fumes or hazardous odours. It can be handled without the use of gloves and it does not require a long time to dry. These are some of the reason why PVA wood glue (also known as carpenter’s glue) is commonly used. However, PVA glue uses can also be industrial in nature. Let’s take a closer look.

Surprising Industrial Applications

PVA glue is very versatile in regards to its industrial uses. For example, it can be chosen as a large-scale primer for plasterboard. It represents an effective paper adhesive; often used in the production of packaging and bookbinding. These observations also arise from the fact that the glue does not degrade over time, so it provides a long-term adhesive solution that is capable of withstanding a fair amount of wear and tear.

A Binding Agent

A handful of lesser-known PVA glue uses should also be mentioned. Its chemical composition allows it to be employed as an ingredient in products including (but not limited to) industrial paint coatings, glass fibres and textile finishes. PVA can likewise be used to create other important industrial chemicals. The two most common are:

• Polyvinyl alcohol
• Polyvinyl acetate phthalate

Widely used throughout the medical sector and additive manufacturing is polyvinyl acetate. Thanks to its low toxicity, other industrial uses such as the large-scale production of certain types of synthetic fibres. Polyvinyl acetate is also used within the photography industry.

Polyvinyl acetate phthalate (PVAP) is commonly used as an enteric coating for medications. This is once again due to the fact that the compound is not toxic to humans.

Industrial Uses Related to Wood

As mentioned previously, some of the most well-known PVA glue uses are related to wood. PVA is soluble in water, so different concentrations can be created based upon the needs of the project in question. It can be used to bond a number of layers of sheet materials together (such as mdf and plywood) thanks to its sheer strength. PVA is particularly suited for gluing together two or more porous surfaces, so it enjoys many applications within the construction sector. Certain products such as Timbond D4 Waterproof PVA Wood Adhesive are likewise effective when bonding wood materials that may be exposed to harsh exterior elements.

Range of Unique Applications

Whether or not we realise it, PVA glue is a critical component within countless industrial manufacturing processes. Although it is indeed useful for common arts and crafts, the unique composition of this non-toxic binding agent has provided benefits for more than 100 years. While technology will continue to advance, this adhesive should “stick around”.
