Nitrile is toxic and a carcinogen. Does that mean that nitrile rubber is also toxic and a carcinogen? I am somewhat worried because i use nitrile gloves for my anatomy class and will stop using them if they are hazardous. —Preceding unsigned comment added by 128.195.63.178 (talk • contribs)

if i autoclave the Nitrile glove, it will decompose to toxic gas?? —Preceding unsigned comment added by 61.10.12.7 (talk • contribs)

A picture of the compound would be nice. —Preceding unsigned comment added by 138.130.47.172 (talk • contribs)

Try having a "Sniff" then let us know :). —Preceding unsigned comment added by 217.5.201.115 (talk • contribs)

At my hospital we recently went to nitrile gloves to replace latex gloves, I have to wonder if this wasn't the best idea. —Preceding unsigned comment added by 66.136.159.157 (talk) 00:49, 16 November 2007 (UTC)[reply]

hai i have problem with oil seal in coal driving motor generally this motor is mounted near electrical arc furnace the function of motor is pump the coal for furnace. the oil seal frequently breakes (every 3 month) we are using nbr type oil seal please give me the suggestion thanking you —Preceding unsigned comment added by 203.187.133.180 (talk) 06:53, 12 October 2008 (UTC)[reply]

Taiwan is part of China and The official name of "Taiwan" government is Republic of China. —Preceding unsigned comment added by 129.97.120.241 (talk) 17:32, 5 May 2010 (UTC) Taiwan is not part of China, China would like to think it is, but it is not. Soon Tibet might not be. Taiwan is an independent country.Black.jeff (talk)[reply]

HNBR

redirected from HNBR to NBR. Neither here nor there is explained, what the "H" of "HNBR" stands for. --Helium4 (talk) 11:16, 25 August 2010 (UTC)[reply]

I believe redirection from HNBR is not correct. HNBR stands for Hydrogenated NBR. It has different properties. — Preceding unsigned comment added by 163.188.46.193 (talk) 21:01, 28 February 2012 (UTC)[reply]

Above's is an old entry but for anyone reading, there's a section in NBR dedicated to HNBR. Also to XNBR. As in types of NBR. --181.165.248.160 (talk) 18:26, 25 June 2017 (UTC)[reply]

Chemical Resistance

Is it resistant to esters?

Can someone explain this?:

In the page it says:

- Nitrile rubber is more resistant than natural rubber to oils

- the more nitrile within the polymer, the higher the resistance to oils

- NBR has good resistance to mineral oils, vegetable oils, (...).

- Nitrile, (...) can be attacked by (...) esters.

How can that be possible?

I mean, isn't vegetable oil a bunch of triesters?

(actually, at first I hadn't found the vegetable oil thing down there, I thought maybe you needed to clarify that NBR only protected from mineral oils. Now I think it may be plain contradiction...)

Also, it seems the "attacked by ozone, ketones, esters, aldehydes"... which in the wiki has a citation needed, is extracted from this website*, but that website isn't a sci study and doesn't cite any study.

http://www.acmerubber.com/nitrile.htm

Which makes this whole thing poor.

Or maybe that page extracted the "attacked by ozone, ketones, esters, aldehydes" from the wiki, like after the wiki was written...

Also: I have just found a website that says they're resistant to esters:

http://www.parish-supply.com/nitrile-and-latex-defined.aspx

"Nitrile offers excellent protection against acids, oils, gasoline, solvents, esters, and grease."

Is it resistant to carboxyles?

Also: Is it attacked by oxhidrile, and esters, but not carboxyles?

Because I wanted to know if it would be resistant to soap.

(even though some websites will tell you they're resistant to soap, but they aren't sci studies : http://www.certified-lye.com/protect.html)

useless comment...

If I found if it's vulnerable to esters or not... I could say if it's vulnerable to vegetable oils or not..

And if I found if it's vulnerable to carboxyles... I suppose soap dissociates the cation and the carboxyle in water? (don't want to look now) So I would know if it's vulnerable to soap too.

What does attacked mean?

Also, when it says attacked... Does it decompose to cyanides that we can absorb? If so, what type of cyanides?* Should we be warned against that?

* (HCN may be more toxic acording to the wiki, although idk if they're saying that it's just as toxic as any cyanide, but it's gaseous)

Health Effects

It's also sad that it doesn't have a health effects section, like PVC has (where vinyl gloves come from), given that Nitrile rubber, or acrylonitrile butadiene rubber, comes from acrylonitrile and butadiene which are both very toxic.

And, as a personal note, I think I get dizzy from them, even though I'm trying to be careful in seeing if it does affect me or not because a search for NBR (or related terms) and dizzyness doesn't result in anything...

There is no mention of the plasticisers used in nitrile rubber. This would be a useful addition. FreeFlow99 (talk) 14:04, 23 March 2020 (UTC)[reply]

Electrical Properties

It would be nice if some information on the electrical insulating properties of Nitrile rubber could be added. — Preceding unsigned comment added by 73.191.192.154 (talk) 14:07, 5 March 2018 (UTC)[reply]

How do you process it?

The article takes us through the production of "crumb rubber." How do you make products from that? Gloves and hoses are not crumbly. Is it thermoplastic (i.e. do you melt it) Hermanoere (talk) 22:29, 15 July 2022 (UTC)?[reply]

Ullmann's encyclopedia shed no light on your question. Maybe the answer is obvious to a polymer expert since the polymerization is complete at the crumb stage. So going forward would require melt or solvent processing.--Smokefoot (talk) 21:58, 16 July 2022 (UTC)[reply]

suggesting wrongly slave labour

The Buna-Werke was a (German) slave labor factory located near Auschwitz and financed by IG Farben. The raw materials came from the Polish coalfields(1).

(1) This sentence has been used in purpose to create false feeling of responsibility and ownership of the German slavery camps. Word polish has been used in the article but word German not. 2003:CB:3702:EA93:4431:AEA3:F8A7:4282 (talk) 09:57, 5 November 2023 (UTC)[reply]
