I was thinking it would be helpful to provide examples of PVA glues. I know Elmer's Wood Glue and Gorilla Wood Glue are pretty popular as far as wood glues go. Noodle24 (talk) 12:39, 30 March 2011 (UTC)[reply]

PVA vs. aliphatic resin emulsion

[edit]

What is the difference between ordinary PVA "white glue" and aliphatic resin emulsion "carpenter's glue" or "Yellow glue"?-96.237.78.13 (talk) 13:11, 17 August 2010 (UTC)[reply]

I think a whole section on PVA glues and their various compositions and properties is warranted. I wonder about the "waterproof" PVA glues like Titebond III, and how others keep microbes etc from attacking. And Mod Podge? --2602:306:CFCE:1EE0:119E:8A:FB6B:2807 (talk) 09:20, 3 December 2017 (UTC)x[reply]
The introduction has been vandalised by somebody who doesn't understand the difference between polyvinyl acetate and polyvinyl acetate adhesive. This aligns with the emerging standard that wikipedia articles require the same skills as a middle school essay. I would agree that an expansion on the topic of PVAc emulsion glues, including their many components that distinguish them from PVAc resin, as well as variation between different formulations, as well as situations where PVAc is used other than in aqueous emulsion, would be very much in order — Preceding unsigned comment added by ~2025-37460-60 (talk) 01:56, 26 December 2025 (UTC)[reply]

as paper adhesive during paper packaging converting

[edit]

What does this mean? — Preceding unsigned comment added by 50.53.245.175 (talk) 01:09, 25 September 2014 (UTC)[reply]

Paper converting is the term used to describe unwinding large rolls of paper and converting it into smaller rolls or pieces/sheets. When converting from a larger roll to a narrower rolls it is called slitting. More complex converting may include applying varies adhesives, printing, die cutting into individual pieces, folding or laminating other layers onto it.

Confusion between Alcohol and Acetate

[edit]

There are repeated references to Poly Vinyl Alcohol in this article, which is about Poly Vinyl Acetate. I think this is due to the natural confusion between two things usually abbreviated as "PVA". I think they should all be reverted to Acetate, but I'm hoping someone more versed in the actual chemistry will chime in.

If this isn't the right solution, I'd appreciate a clear explanation of the relationship between them, with links here and from Poly Vinyl Alcohol. --2603:3024:1405:D00:89B1:A100:27EE:544B (talk) 02:49, 27 March 2018 (UTC)[reply]

Solubility & Toxicity

[edit]

I have come across a PVA string which is claimed to be soluble in water and safe: http://vi.raptor.ebaydesc.com/ws/eBayISAPI.dll?ViewItemDescV4&item=123939270770&category=179972&pm=1&ds=0&t=1573990848343

Is this the same material? Is the plastic soluble and harmless? IS the glue, when set, soluble and harmless? FreeFlow99 (talk) 11:51, 17 November 2019 (UTC)[reply]

If it's deliberately soluble in water, that'll be polyvinyl alcohol, not polyvinyl acetate. The two are widely confused. I've no idea why we haven't worked out a rational pair of distinct acronyms for them by now. Andy Dingley (talk) 12:05, 17 November 2019 (UTC)[reply]
Thanks Andy. However I don't see a reference to solubility in the polyvinyl alcohol article (perhaps it needs improvement), though I do see a mention of soluble polyester in the polyester article. I agree that we ought to stop using the term PVA for the alcohol and use PVOH instead; even if we only do that within Wikipedia to avoid confusion.

PVA Glue Setting

[edit]

Please would someone knowledgeable add information about how PVA glue sets ? Does a solvent dry out, or does it react with air or moisture ? Thanks for any help ! Darkman101 (talk) 08:34, 22 August 2020 (UTC)[reply]

boiling point in table

[edit]

pvac degrades when heated, it does not boil ~2026-36515-8 (talk) 15:07, 17 January 2026 (UTC)[reply]

I deleted boiling point from the properties table with this rational:
"High molecular weight polymers do not change from a liquid to a gas, i.e. boil. They will depolymerize or degrade first. The reported boiling point may be a theoretical calculation without any proof that the calculation applies to polymers. No experimental data is reported to support the boiling point data. If there was a boiling point, one would expect that it depends on the molecular weight, similar to a series of alkanes or alcohols of increasing molecular size."
So what was the molecular weight polyvinyl acetate whose boiling point was reported?
The concept of polymers boiling is so unreasonable that I was unable to find a good source stating that they do not boil. For example. boiling is not mentioned at all in the Wikipedia article on polymers. Also, no experimental data on boiling of high molecular weight polymers can be found searching the web.
I do not know how, when, or why boiling point data was added to this or other polymer articles, but it is erroneous and should be removed. For point of reference, I have a B.S. and a PhD in polymer science and engineering, not that it matters to the Lords of Wiki. Anoldnewb (talk) 20:42, 20 January 2026 (UTC)[reply]
