What is the difference between PVA glue and Elmers glue?

What is the difference between PVA glue and Elmers glue?

chemantics4 years ago
Elmers glue is PVA (PVAC) based - but has lots of other stuff (tackifiers and solvents), and has a pH of 5 (meaning it is acidic). For book binding, I would definitely recommend using a pH neutral PVA based glue that is specific to book binding. The acid in Elmers has a nice way of breaking down the cellulose in paper over time, and who knows what the other ingredients might do.

Wouldn't that apply to any cellulose product, eg. wood? My mother has a popsicle stick jewellery box I made for her about 40 years ago using Elmer's white glue. Other than re-gluing a couple of the sticks that were knocked off over the years, there is no evidence of any acidic deterioration that I have seen.

Paper is different to wood, it's thinner and heavily processed. L

A project making sand bowls specifys Elmers white glue.
Can't get it in UK unless its shipped over from USA and the shipping cost makes it expensive.
I thought general PVA glue the sort used in kindergartens, schools etc would be ok.
Can anyone advise.
Thanks!

PVA = Polyvinyl Acetate...Don't worry about the brand name. It's essentially white craft glue. "Elmer's", actually has a higher than average Ph than most PVA's and depending on the wood you plan on using, it might cause staining...hope this helps.

I was just going to say that Elmers is made by a cow. I'm glad you knew the right answer.
Actually, Elmers glue is entirely derived from petroleum products. This is from their FAQ: "Do you use animals when making glue? No, Elmer's does not use animals or animal parts to make glue. Our products are made from synthetic materials and are not derived from processing horses, cows or any other animals. "
And where do you suppose those petroleum products came from?

https://en.wikipedia.org/wiki/Petroleum#Formation

Just dead stuff that was once alive, and has been dead for a VERY long time. Sure it didn't come directly from the animal, nature recycled it first...
According to the Material Safety Data Sheet (MSDS) for Lineco pH Neutral PVA Adhesive, its pH is between 4.0 and 6.0, while Elmer's Glue-All is between 4.8 and 5.1 according its own MSDS.

I expect that Elmer's Glue-All is sufficiently "pH neutral" for most purposes.
Jade 403, on the other hand, is 7.1 to 7.3, so which PVA you use *is* important for archival purposes.

None. Elmer's glue is PVA glue, poly vinyl acetate.

So when doing book binding and it says to use PVA glue, I would be just fine using Elmer's?
I think Chemantics deserves Best Answer :-)
Yep. Elmers is a very typical "white glue".

Are some white glues better than others?

Possibly, the formulation is basically the same for all PVA glues but the purity may vary due to the manufacturer's quality control process. I have pretty much limited my use of PVA to two brands, Elmer's and Titebond with no discernible difference, except Elmer's seems slightly more viscous than Titebond. I've seen some Chinese made PVAs in the dollar store but never used them, the price difference between them and the Elmer's and Titebond is negligible.
