Talk:Styrofoam

message: I have removed the following sentence "U.S. Environmental Protection Agency (EPA) states on its website: "Each year Americans throw away 25,000,000,000 Styrofoam cups. Even 500 years from now, the foam coffee cup you used this morning will be sitting in a landfill."[9]" from this section since at the start of the article they explain that expanded polystyrene cups are not styrofoam. The source of the sentence was http://www.epa.gov/reg3wcmd/solidwasterecyclingfacts.htm if anyone is interested in putting it back. --Spuzzdawg (talk) 23:59, 21 April 2012 (UTC)

Aslo, why exactly have we gotton rid of all the citations?  Aren't we supposed to be encouraging them in wikipedia?Mr. Recycle 19:04, 13 April 2007 (UTC)
replies: text: Someone using IP 206.40.109.91 blanked the page, and then someone "fixed" it by rewriting the intro of the old version instead of just reverting the blanking. I've restored the pre-blanking version; I think the ban information you added is already in there, but double checking wouldn't hurt. I didn't see any other additithis on the polystyrene page. I've made this back into a redirect to there, and moved the pertinent information. Maximus Rex 23:58, 5 Dec 2003 (UTC)

text: Xerox, the company, makes things other than photocopiers.  Several paper products are sold under the brand name Kleenex.  The name Styrofoam refers to one thing only: expanded polystyrene.  FireWire (TM Apple) and iLink (TM Sony) and IEEE 1394 all point to the same page.  Tylenol and acetaminophen are different pages, but again, there are multiple Tylenol products; acetaminophen is just the most popular.  Merge if reasonably possible.  71.41.210.146 19:38, 4 May 2007 (UTC)
thread_title: Unsourced Facts

message: I was curious about what method is used to assemble expanded polystyrene beads into a form.  I checked the polystyrene article first and it mentioned this article.  It seems appropriate since in america we refer to cups made out of expanded polystyrene beads as "Styrofoam".  Does anyone have any information on the manufacture process, specifically are they glued together or heat formed or what?  Thanks. 76.212.152.1 08:48, 29 August 2007 (UTC)
replies: text: I will put something in the polystyrene article, but not in the Styrofoam article. Have a look at some of the previous talk. Polystyrene pellets containing a volatile blowing agent are heated in a closed mold. The pellets soften and expand as the blowing agent volatalizes. The expanded particles partially fuse due the heat of the process. Silverchemist 03:46, 30 August 2007 (UTC)

message: I removed the picture showing a small piece of exposed Styrofoam insulation, which is a firecode violation. Even though this is explained in the caption, IMHO the relevance of the picture doesn't justify its inclusion (it would be better suited to an article on firecodes or fire safety). If someone had a picture of a partially constructed house with the Styrofoam still exposed, that would be a much more useful image in this article.Silverchemist 02:31, 13 September 2007 (UTC)

message: If there are lots of editors confused about expanded polystyrene vs. Styrofoam, there must be even more readers who are confused.  Would it help it we had a separate article on expanded polystyrene, rather just the section in polystyrene? Ccrrccrr (talk) 11:43, 20 June 2009 (UTC)

message: well guess what, instead of paper plates we had this darned styrofoam plates that contain styrene. I didnt know that if you reheat food in the microwave on them, that the styrofoam can melt parts of the plate into smaller peices. these peices can get mixed into your food or sauce. Then you can accidentally consume it because its flavored with the foods sauce, and not even realize it. Well this just now happened to me and im mad. someone write something to warn people. Who knows if ill digest the plate peices and get sick or not, but im still furious that this could happen. these companies have no business making plates out of toxic materials to BEGIN with. I hope someone sues the pants of kroger and other companies that make these plates!  —Preceding unsigned comment added by 98.160.131.17 (talk) 22:33, 6 November 2010 (UTC)
replies: text: Firstly, the plate you were eating off (and later eating) was made of expanded polystyrene, not Styrofoam. Any plastic plate will melt eventually and you should check to see which ones are suitable for use in a microwave oven. Polystyrene is not toxic and the saying "this too shall pass" applies to ingested polystyrene. Kroger (the supermarket chain, I presume) does not manufacture polystyrene plates. Just out of curiosity, what food were you eating that could not be distinguished from polystyrene plate pieces? IMHO, no warning needs to go into this article.Silverchemist (talk) 00:24, 7 November 2010 (UTC)

message: The image on this page appears to be a sheet made from expanded polystyrene balls. Styrofoam, the specific product, is a form of extruded polystyrene. Its is characterized by a fairly homogeneous porous structure, unlike expanded polystyrene sheets which are formed from compresses masses of expanded polystyrene balls  —Preceding unsigned comment added by 86.164.124.110 (talk) 17:14, 14 February 2011 (UTC)

message: Does Styrofoam generally have the same melting point as polystyrene?
Or do different kinds of styrofoam have different melting points?
I live in Portland, Oregon, where it is very controversial putting polystyrene into the garbage.    The local sanitation service gets mad at me when I attempt to put plastic bags into our garbage can.   As for myself, I would like to recycle polystyrene, whether in foam form, or puffed pellet form ("peanuts").   I also happen to have a lot of plastic bags I want to get rid of.   Or better yet, mix them together, melt it all down into a single liquid substance, and make something useful out of it. I want to point a heat gun at it, liquefy it, and pour the fluid down a funnel into forms.   I was hoping Wikipedia would have an article on this sort of thing.    
Is recycling polystyrene more dangerous than one might first think?   216.99.219.42 (talk) 06:53, 18 September 2011 (UTC)

message: This should be moved to extruded polystyrene foam and styrofoam made into a disambig between extruded and expanded polystyrene foam. Ausir (talk) 00:50, 27 June 2018 (UTC)
replies: text: Great idea. Given that there's been no objection, I will move the current page to Styrofoam insulation, and make styrofoam a disambig. Wikiacc (¶) 20:19, 9 August 2018 (UTC)
replies: text:  It's kind of hard for anyone to comment on a move proposal that you keep a secret.  It's NOT a great idea.  Now we've got a disambiguation page that is linked from 200+ articles that used to link to a relevant topic article.  Please see WP:FIXDABLINKS.  And we've got a disambiguation page that lists articles about (1) a material, (2) three different products made out of that same material, and (3) a musician.  This is really a WP:TWODABS situation with a very clear WP:PRIMARYTOPIC. --R'n'B (call me Russ) 21:59, 9 August 2018 (UTC)
replies: text: I agree totally with Russ except for the last point.  The three products listed are not made out of branded Styrofoam extruded polystyrene, but from the confusingly similar generic styrofoam expanded polystyrene.  120 articles link to sytrofoam (lower case s), and many such as Disposable tableware are referring to expanded polystyrene foam rather than Styrofoam insulation. Is there really a clear primary topic? Certes (talk) 11:50, 10 August 2018 (UTC)

text:  if you're wondering about the sudden interest in this page, it's currently at the top of the Disambiguation pages with links list, which ideally would be empty. Certes (talk) 11:54, 10 August 2018 (UTC)

text: * Sorry to everyone who had to clean up after this move; it was hasty and I didn't take the time to familiarize myself with the process at Wikipedia:Requested moves beforehand. The reactions suggest that this would be a controversial proposal even if done correctly. Although I fully endorse Certes's point above, it may suffice to check the incoming links regularly and change the ones intended for lower-case styrofoam. So, while I would vote to move if it were proposed, I will not be proposing it now. Wikiacc (¶) 01:24, 11 August 2018 (UTC)
replies: text: I went through the links to styrofoam (lower case) yesterday and diverted those that were obviously generic ("a styrofoam cup", etc.) to expanded polystyrene foam.  A very few clearly meant the brand, so I gave those a capital S.  That leaves about 90 wikilinks which should be changed one way or the other but I don't know the topic well enough to decide which.  None of that work results from the page move, so thank you for highlighting an existing problem. Certes (talk) 11:37, 11 August 2018 (UTC)
