Is PVA Glue Eco Friendly?

We use many products in our daily life. For repair, each product and equipment need another one in addition. To fix, attach, or build something, you need to use glue that can go with anything. There are many types of glue you can find in the market that can fulfill your requirements. One of them is PVA glue.

We always try to get the best of the best products. It is important to consider the effects of the products on our family and environment. Many of these products are guileful and may use harsh or even toxic chemicals to make their product in the cheapest way possible. These products are completely disregarding the safety and health of consumers and environmental sustainability.

According to that, PVA glue is one of the products that remain in our questionable minds. Is PVA glue eco-friendly? Let’s find out.

Key Takeaways

PVA in PVA glue is known as polyvinyl acetate, which is a synthetic polymer being produced for over 100 years.
Even though the PVA glue is made up of synthetic products, the manipulation of its structure makes them biodegradable.
Environmental effect of PVA glue is quite small which makes it a popular household product.
Take some precautions before and after using PVA glue as it is still an adhesive.

What is PVA Glue?

PVA glue is a kind of glue to fix or attach any kind of material. The acronym “PVA” stands for polyvinyl acetate which is an aliphatic rubbery synthetic polymer. PVA was discovered in 1912 in Germany. It is one of the most famous and widely used water-dispersed adhesives, made up of a water-based emulsion type of glue. It is known by many names as wood glue, white glue, carpenter’s glue, school glue, but most commonly PVA glue.

PVA may be added to cement or concrete as it can improve the water-resistance properties. Thus, PVA is an emulsion, not a true water solution. PVA setting and curing are accomplished by the removal of water due to evaporation or absorption into a substrate. PVA adhesives produce clear, hard films that have good weather resistance and withstand water, softening at 30–45 °C, good biodegradation resistance, poor resistance to creep under load, and low cost.

What is PVA Glue Made Of?

PVA glue is mainly made of aliphatic rubbery synthetic polymer. The formula is (C₄H₆O₂)n. PVA is normally manufactured through the free radical polymerization of vinyl acetate, which is synthetic.

Many ingredients used to make synthetic PVA glue are plastic polymers and petroleum-derived. The petroleum industry is extremely destructive and these products do not break down readily after being rejected. Scientists isolate this compound and then manipulate it to slightly change its structure. Most of the time this happens in water.

Monomer molecules of vinyl acetate typically react when they are submerged in water and usually create an emulsion that is milky white in color. The emulsion fluid in most can cases be instantly processed as a polyvinyl acetate polymer by removing it from the water and allowing it to stabilize at room temperature. This is how PVA glue is made.

Is PVA Glue Eco-Friendly?

According to the ingredients of PVA glue, it is synthetic because it is made up of by-products of the petrochemical industry. However, it is 100% sustainable for our environment meaning it is not bad for our environment. This is because PVA glue is biodegradable, where natural microbes like bacteria can break it down to form water, acetic acid, and natural gases. Surprising right?

That is what makes it so popular among household equipment all around the globe. It is easy to apply, it dries clearly and very quickly. Most PVA glue dries completely within 24 hours or even less.

PVA glue is non-toxic for kids and pets. It only begins to release toxic vapors when you burn it. So, when you use it properly, it is a safe glue that will not damage our atmosphere. Though, some PVA products contain high levels of VOC emissions. It is possible to find low-VOC glue. You just have to keep an eye on the fine print on the glue labels.

So, consider it to be a glue that is good for your family and the environment. If you can recycle the glue and the packaging that the glue comes in then you have found a product that is doing wonders for our planet earth. And that does not seem as tricky as it used to be as many manufacturers are trying to make their product packaging greener.

Precautions

Though, PVA glue is fully eco-friendly and safe to use at home. There are a few things you need to maintain while using this glue.

The ingredient of this glue is a synthetic polymer that is plastic-like. To use it for daily use, keep it out of children. They have a common nature to put everything in their mouth. No matter how safe PVC glue is, it is not for ingestion at any point. Even it will be dangerous if someone eats it.

This glue is quite strong when in direct contact with skin. So, put your gloves on before using them. It will be itchy in contact with the nose, eyes, and facial areas. Keep the container of PVA glue in a safe place.

The glue material is fine for our nature. But the packaging should be of concern. PVA glue comes in a plastic container that is a waste that goes to nature. Now, PVA can be easily decomposed in the soil. But the packaging will remain the same and pollute our environment for a long time. To avoid that, use a recycling process and put it in on dustbin so it can be taken care of. Help our world become a better living place.

Use of PVA Glue

PVA glues are the most common for use in carpentry. PVA glue is particularly used for gluing porous materials, particularly for wood, paper, and cloth. It does not contain solvents and acts as a useful consolidate for porous building materials like sandstone. PVA adhesive is flexible, delivers a very strong bond, and unlike many polymers, is not acidic. PVA wood glue is most often used:

A wood adhesive
As a paper, fabric
Leather adhesive like shoes
Bookbinding
Arts and crafts
As envelope adhesive
As wallpaper glue
A drywall primer
As a filler by adding sawdust to it

A mixture of PVA and water makes a very good sealant for plaster. Preparing it for painting or wallpapering. It can also be used as a non-waterproof interior varnish, perfect for paper-mache projects

FAQs

1. Is PVA glue natural?

PVA glue (Polyvinyl acetate), also known as white glue, is the most used glue in wood construction nowadays. It is a product of the petrochemical industry. It can be seen as microscopic plastic particles thinned in water. Even though it is a synthetic thermoplastic, it biodegrades under the right conditions.

2. Is PVA glue toxic?

PVA is a low-cost, water-based, non-toxic way to glue wood and leather. Wood glue is a particularly strong version of ordinary PVA and it is ideal for heavier jobs. It dries completely clear but you can also buy pre-colored versions that are less visible on wood surfaces.

3. What is one drawback of using PVA glue?

The downside of PVA Glue is, you can’t varnish over PVA, but you can still paint over it. It can take up to a full day for the PVA bond to reach full strength. PVA is water soluble, so dried PVA bonding can soften if exposed to water.

4. What is PVA good for?

PVA glue is a synthetic polymer used as a gum for absorbent materials. PVA glue is used to secure or paste things like clothing, paper, and wood among other things. It’s a very adaptable adhesive, not only for using it in many different materials but also it is inexpensive.

5. How long does PVA last?

The recommended lifespan on PVA glue is generally a way for the company to cover its butt. One year is simply the length of time the company will guarantee the quality level. But most strong glues can go for two years or more if it is stored constantly at room temp. Luckily, the glue will act odd and show problems when it is bad.

6. What is an alternative to PVA?

Calcium Stearate is an Effective Alternative to Polyvinyl alcohol in Poly-Lactic-co-Glycolic Acid Nanoparticles Synthesis.

Final Thoughts

PVA glue is a 100% eco-friendly product for our daily use. There is no doubt about it. The ingredients of PVA are pretty harmless and it is very easy to use. To maintain a sustained environment, you should follow the recycling process. Overall, this glue is safer and easy to use than any other glue on the market because it is water-based.

Finding biodegradable glue is important as it helps you to do a little more for looking after our planet and the safety of the water. I am sure that your mind at ease by knowing that PVA glue is biodegradable.

As you have seen, when in a dried state, it goes back to a polymer and the elements constitute which are then processed by microorganisms. Buying a bottle of PVA glue is not just handy for your DIY work, but it also extends the life of mother earth.
