Airsoft guns

Great article, http://bits.wikimedia.org/static-1.20wmf5/skins/common/images/button_media.pngI airsoft, and many airsoft guns are composed of ABS plastic. It's nice to know what it's really made of!— Preceding unsigned comment added by 69.237.21.118 (talk • contribs) 03:25, 18 January 2006

Temperature?

Used at up to 60 °C, eh? Is this the reason the ABS vent on some water heaters becomes damaged, brittle, and eventually snaps?— Preceding unsigned comment added by 72.142.61.182 (talk • contribs) 03:07, 9 April 2006

"In plumbing, ABS pipes are the black pipes " - believe this is incorrect (should be polyethlyene instead of ABS), and should be withdrawn from the article. 58.166.34.212 02:23, 31 May 2007 (UTC)

In Canada, all 'drain waste and vent' plumbing must be ABS and it is all black. --64.25.174.101 (talk) 19:59, 9 October 2010 (UTC)

I agree. I've removed the offending text. Here's a link to the white ABS domestic waste pipe I just bought - http://www.diy.com/diy/jsp/bq/nav/nav.jsp?action=detail&fh_secondid=9272031&fh_view_size=6&fh_location=%2f%2fcatalog01%2fen_GB&fh_search=40mm+waste+pipe&fh_eds=%C3%9F&fh_refview=search&ts=1228741056300&isSearch=true. —Preceding unsigned comment added by Abainbridge (talk • contribs) 13:06, 8 December 2008 (UTC)

ABS is used in in the extruding of pipe for many applications, specifically underground, RV, boat and trailer. ABS pipe is in most cases black in color so it can be differentiated from other materials. —Preceding unsigned comment added by 68.46.218.62 (talk) 01:11, 23 April 2009 (UTC)

Melting point?

there's a physical properties section but it needs more detail --Treekids (talk) 20:19, 25 November 2009 (UTC)

And in Australia, DWV products are made from uPVC for low-pressure systems and a polybutadiene variant for high-pressure systems. Not everyone on Wikipedia is from North America, you know :) Old_Wombat (talk) 05:37, 19 February 2012 (UTC)

Molded ABS retains residual stress within the material due to the molding process. These can be seen by illuminating the molded material with ultraviolet light.WFPM (talk) 22:18, 6 March 2013 (UTC)

Mention of Lego?

I think maybe that this material is used for lego should be mentioned as lego is one of the more popular toys in the world.# --Jamieisamonkey 18:48, 8 October 2007 (UTC)

edit: lol, dont worry. ive just reread the aricle. the mention of lego is there but maybe make it more obvious? —Preceding unsigned comment added by Jamieisamonkey (talk • contribs) 18:49, 8 October 2007 (UTC)

I've moved all the applications of ABS out of the lead section and scattered throughout to a new Applications section.—Quicksilver^{T @} 12:27, 22 October 2010 (UTC)

OK, this was a long time ago, and I dont have any references for it, but ... Either the EU or the Swedish government declared that ABS plastic was "harmful". Lego has been trying since 2012 to find a substituate for it, with no success. — Preceding unsigned comment added by 2001:8003:E422:3C01:E9F4:68A4:7061:4BC3 (talk) 05:29, 21 November 2021 (UTC)

Question about safety when used for kids bowls/cutlery?

-- I've noticed ABS is used in some other kids stuff, like eating bowls. Is it a "safe" plastic - i.e. does it leach harmful materials? It would be good to include comments about this in the post. Thanks -- —Preceding unsigned comment added by 216.21.149.156 (talk) 02:43, 13 January 2008 (UTC)

Phthalates

Talking about safety, I would like to know if all ABS products are phthalate free, meaning they comply with the phthalate ban for toys intended for children 12 and under. This information can save companies thousands of dollors avoiding unnecessary testing.Ddad312 (talk) 16:30, 5 March 2009 (UTC)

Glues?

A section on the appropriate glue to use on ABS would be nice. 71.104.113.44 (talk) 17:38, 9 August 2009 (UTC)

OK, this is a long time ago, but "Superglue" (acrylocyanite???)) and terachloroethylene (model aircraft cement) are both solvenet adhesives for ABS, that properly applied result in a bond as strong as the plastic itself. — Preceding unsigned comment added by 144.136.34.40 (talk) 08:34, 25 June 2018 (UTC)

Polymerization?

Nothing in the article gives any indication when the polymerization takes place. I assume it is before it is melted and molded. But that it not clear to me. If you know could you add a sentence about this, include something about chain length, and an example of the final polymer.

Safety

The following discussion is closed. Please do not modify it. Subsequent comments should be made in a new section.

This page needs a safety section; anyone care to write it? — Preceding unsigned comment added by Superhands99 (talk • contribs) 23:22, 3 July 2011‎

I can write it. Kci357 (talk) 11:52, 8 December 2011 (UTC)

Last time you did that, you were indef blocked for it. I see that you've just added another safety section, which I've reverted. This was hugely biased (again, for the same reason as your past block). You take real hazards and inflate them out of any reasonable proportion. Your sourcing is weak too - I particularly liked the one from the artist who objected to hand sanding ABS plastic, on the basis of comparing its precursor chemicals to anthrax!

If you want to remain unblocked, it would probably be wise to remain well away from this obsessive topic. If you insist on writing an addition here, it needs to be accurate, balanced and well-sourced. Scare-mongering is no part of this. Andy Dingley (talk) 12:05, 8 December 2011 (UTC)

Superhands is another obvious sock of KCI357 and has been blocked along with the sockmaster. If further socks pop up trying to add the same or similar info yet again, please take it immediately to ANI for immediate blocking. Toddst1 (talk) 16:09, 8 December 2011 (UTC)

The discussion above is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.

Adhesive?

I'd like to echo the previous remark about including information for a good adhesive (presumeable although not necessarily a solvent cement) for ABS. The list of solvents is good, but not quite enough. Old_Wombat (talk) 05:32, 19 February 2012 (UTC)

Monsanto used to make a suspended ABS liquid glue that could be used to glue join pieces of abs, and also to create an ABS property edge bond of materials by coating the joined edges that was very effective. I think it was called Marbond 11.WFPM (talk) 02:35, 6 March 2013 (UTC)

ABS plastic is a preferred plastic for molded cell cases for special purpose battery cells. The control of the plasticity of the molding material is important to maintaining the molded strength of the molded cell cases. The stress lines remaining in the molded cell case could be seen by illuminating the cell case with ultraviolet light.WFPM (talk) 02:43, 6 March 2013 (UTC)

Safety - CMR ingredients

I am surprised there is no safety/health section for this (and after checking the talk page I see it is contentious to add one) since ABS contains Acrylonitrile and Butadiene which are recognised as Cancerogenic, Mutagenic and toxic for Reproduction, categories 1 or 2. This means, in the EU at least, they are being phased out of use as much as possible.83.70.170.48 (talk) 10:57, 8 January 2013 (UTC)

Most interesting. In that case, what is Lego (which is totally produced in the EU) going to use if it can't use ABS? Old_Wombat (talk) 10:35, 8 April 2013 (UTC)

The original comment here is just yet another unfounded scare-mongering by a blocked sock. Andy Dingley (talk) 11:53, 8 April 2013 (UTC)

Uhh, which part is scare-mongering? That there is no safety/health section? That it is/not Cancerogenic, Mutagenic and toxic for Reproduction? That it is/not being phased out in the EU? Old_Wombat (talk) 10:46, 23 September 2013 (UTC)

since ABS contains Acrylonitrile and Butadiene That a given material is made from something doesn't necessarily mean it contains that something. Even if a material actually contains something doesn't necessarily mean it has enough to be a safety hazard. Furthermore, in this case, ABS is not a uniform product, so one type of ABS may or may not have the same hazards as another type. "Scare-mongering" is any reference to such allegations which do not address those concerns and others. --Kennkong (talk) 03:23, 5 January 2014 (UTC)

Dead Link(s)

Under External Links, "Comparisons of many physical properties with other plastics" http://www.machinist-materials.com/comparison_table_for_plastics.htm seems to no longer function. It looks like a supplier that is not operating the website. "Forbidden You don't have permission to access /comparison_table_for_plastics.htm on this server." — Preceding unsigned comment added by 70.238.137.57 (talk) 23:43, 6 April 2013 (UTC)

Second paragraph under Production should be in Properties?

"ABS combines the strength and rigidity of acrylonitrile and styrene polymers with the toughness of polybutadiene rubber. While the cost of producing ABS is roughly twice the cost of producing polystyrene, it is considered superior for its hardness, gloss, toughness, and electrical insulation properties."

Except for the reference to the cost of production, this paragraph is about the properties. Should this be added to or merged with the Properties section? --Kennkong (talk) 20:28, 3 January 2014 (UTC)

Plating ABS

Can ABS plastic be plated with nickle or copper?74.195.121.194 (talk) 21:59, 10 June 2015 (UTC)

Yes, with the same sort of process as other plastics. ABS works well and more easily than many other plastics. It's usual to plate first with an electroless process, then to deposit thicker layers, if needed, by electroplating. This is quite commonly done for EMI shielding. Andy Dingley (talk) 00:10, 11 June 2015 (UTC)

Chemical Resistance?

I noticed that the Polycarbonate article has chemical resistance listed on the right bar as well as other information that seems to be missing from the ABS article. Can I change that? Here is my source for the data http://www.rtpcompany.com/technical-info/chemical-resistance/ http://www.wolframalpha.com/input/?i=abs&a=*C.abs-_*MaterialClass-

== Airsoft Imitation Arms == The majority of Airsoft rifles on the market today use ABS as their main material alongside various metals. Most low end rifles and pistols have poor quality ABS with exactitude lapping left over from moulding templates. This might want to be added to the article Also a question, what's the melting point of ABS I need to melt two broken pieces together to fix one of my guns without it burning up in flames like it explains in the article. Note: Usually only the guns themselves are made of ABS, not the pellets/BBs and to answer someone else's question I think ABS is relativity safe as a food container/cutlery —Preceding unsigned comment added by Zzzyax (talk • contribs) 13:15, 9 July 2008 (UTC)

Thermal Properties

Coefficient of thermal expansion is given in units of kV/mm - is this right? wouldn't % or ppm be more usual? — Preceding unsigned comment added by 89.248.29.35 (talk) 12:29, 3 June 2016 (UTC)

The dielectric constant of ABS is 15-52 kilovolts per millimeter (kV/mm). Perhaps someone copied this electrical property into the thermal section? (Thank heavens for units!)
I'm removing it for now, we can add in something correct from readily available literature sources later.
(For the record, thermal expansion coefficients have units of dimension 1/Temperature, for example 1/K or or ppm/°C or %/°F )

Methyl methacrylate-acrylonitrile-butadiene-styrene

I've recently obtained some "transparent ABS" or MABS or Methyl-methacrylate Acrylonitrile Butadiene Styrene. Searching on Wikipedia doesn't seem to contain any information. It would be nice to see some added here or perhaps on it's own page. Andypreston (talk) 12:27, 8 April 2017 (UTC)

Sounds like it's a copolymer between PMMA / acrylic (aka Perspex / Lucite) and ABS. Andy Dingley (talk) 14:19, 8 April 2017 (UTC)

Use in 3D printing

As ABS is a popular feedstock for 3D printing could more detail on these aspects of its use be included here, as with PLA? Stub Mandrel (talk) 07:19, 25 August 2017 (UTC)
