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 184.108.40.206 (talk • contribs) 03:25, 18 January 2006
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 220.127.116.11 (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ABS pipes are the black pipes " - believe this is incorrect (should be polyethlyene instead of ABS), and should be withdrawn from the article. 18.104.22.168 02:23, 31 May 2007 (UTC)
- In Canada, all 'drain waste and vent' plumbing must be ABS and it is all black. --22.214.171.124 (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 126.96.36.199 (talk) 01:11, 23 April 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)
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.—QuicksilverT @ 12:27, 22 October 2010 (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 188.8.131.52 (talk) 02:43, 13 January 2008 (UTC)
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)
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.
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.184.108.40.206 (talk) 10:57, 8 January 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)
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 220.127.116.11 (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)
Sources for section "Hazard for humans"
- (complex experiments, non-free) Respiratory Responses of Mice Exposed to Thermal Decomposition Products from Polymers Heated at and Above Workplace Processing Temperatures - http://www.tandfonline.com/doi/abs/10.1080/15428119491018420
- (nano-dust, free) Ultrafine particle emissions from desktop 3D printers - http://www.sciencedirect.com/science/article/pii/S1352231013005086
- 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)
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-
|Resistance to Weak Acid||Excellent|
|Resistance to Strong Acid||Good|
|Resistance to Weak Alkalis||Excellent|
|Resistance to Strong Alkalis||Excellent|
|Resistance to Organic Solvents||poor*|
|Resistance to Alcohols||Poor|
|Resistance to Hydro Carbons||Poor|
|Resistance to Fuels||Poor|

|== 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)
