Talk:Polyoxymethylene

message: * Whatever takes place in the merging of these two articles, the main body of the text ought to remain with the most widely known name, DuPont's trade name, Delrin. In a reference work, communication takes precedence over classification, and to do so is no error of fact.

* They shouldn't be merged. Just provide links to the related reference. The information in each is useful in different ways to different types of people. If they are combined then readers will be forced to read information that they are likely to consider not useful. In this example Delrin is a useful material for people and organizations crafting items that don't care how it came to be or what the molecular structure is.—Preceding unsigned comment added by  66.188.120.241 (talk • contribs)  17:01, 21 May 2006
*There may be some content that may be merge-able. However, a Delrin article should still exist on its own. It would be like merging the term Big Mac into hamburger or Laser into into sailboat.—Preceding unsigned comment added by  64.187.15.104 (talk • contribs)  14:19, 15 June 2006
* I agree with above comments, Delrin should be kept seperate, but links should be placed relating the two—Preceding unsigned comment added by  24.158.91.231 (talk • contribs)  02:18, 21 June 2006
* I also agree with these comments as well. Delrin and Polyoxymethylene are on a molecular level the same, however from a historical standpoint, the two are distinctly different.—Preceding unsigned comment added by 68.34.78.194 (talk • contribs)  01:21, 10 July 2006
* I disagree.  Delrin, by definition and molecular structure is polyoxymethylene.  The two are indistinguishable and are therefore identical.  Just as 'Big Mac' is the name given to a hamburger by a company, 'Delrin' is a name given to polyoxymethylene by a company, but a Big Mac is just a burger and Delrin is just polyoxymethylene.  "Laser and sailboat" have nothing to do with each other or this discussion.  The Delrin article should be merged, but kept as a separate bullet.—Preceding unsigned comment added by SuperFluid (talk • contribs)  17:46, 18 July 2006
* I disagree as well. The properties of materials are directly related to their chemical structure. Also, wouldn't it be strange if the definition of e.g. polystyrene could only be found under "plastic coffe cup" ? Wikipedia should try to be as basic as possible. Delrin is just a brand. However, I feel that searching "delrin" should still lead one to POM. (note.: a "laser" is actually a type of sailboat)—Preceding unsigned comment added by Sikkema (talk • contribs)  13:29, 26 July 2006
* I'm joining the dissenters, because as far as the practical uses are concerned, they are identical.  Delrin shouldn't be separate just because DuPont has dominated the market for polyoxymethylene, thus permeating the vocabulary with a brand name.  Do they perform a different function?  Of course, all brand names of POM should lead to the same page, as they are functionally identical as well.  Keep the Big Mac talk to the McDonald's page and the Delrin talk to the DuPont page.—Preceding unsigned comment added by HuntClubJoe (talk • contribs)  21:02, 24 September 2006
* It's fine to merge them as long as a search on "Delrin" takes me to this page.  I didn't know what Polyoxymethylene was (until now) but I had heard of Delrin.  Laser is to sailboat as Ford is to car.—Preceding unsigned comment added by 192.153.157.50 (talk • contribs)  06:04, 3 October 2006
* I support the merger and agree that a search for Delrin should lead to the article on Polyoxymethylene, just as one for Hostaform and POM should. Delrin's dominance is not worldwide, I know this material as POM, and here the most popular brand is Hostaform. Wikipedia should be relevant for a worldwide audience; if you want to know more about Delrin, visit the DuPont website.—Preceding unsigned comment added by 62.128.27.2 (talk • contribs)  10:56, 20 October 2006
* Support the merge, or either leave Delrin to a bare minimum, and move all info to this article.  --Dirk Beetstra T C 10:17, 20 October 2006 (UTC)

message: The M16 is made out of Derlin, the army claim its designed for battlefield survivability compared to the alternative of aluminium due to its durability and impact resistance, resistance to chemicals used in combat (e.g Orange) , and the fact that it is UV stable for outdoor use in sunny climates (Read: Vietnam)
Seeing as the M16 was early 60s, could this be a good example of derlin in large scale use? The idea of a plastic rifle was revolutionary at the time, and well, a large number of A1s are still in gfood condition today, so it obviously lives up to durability.

message: Polyoxymethylene is very commonly (probably most commonly) referred to as acetal in the USA.  A search on
[Matweb:acetal] returns a list of 1082 materials, 
[Matweb:pom] returns 585 materials, 
[Matweb:polyacetal] returns 26 materials,  
[Matweb:polyformaldehyde] returns 13 materials.
While not a chemically correct name, Acetal appears to be the most common name.  Acetal is generally a copolymer or a homopolymer.

message: These sentences under "Usage" aren't clear:
Model: Thin, later claimed Modellbahnen parts, such as bogies and handle bars. POM breaks under load slightly less than ABS, but in bright translucent colors, and not paintable.
Also under "Usage," next to "Furniture," should "curtains rolls" be "curtain rods"? I'd correct these myself if I were more knowledgeable on the subject. Mr Instamatic (talk) 14:11, 30 August 2011 (UTC)
thread_title: Clarification

message: According to http://es.wikipedia.org/wiki/Junta_de_vidrio_esmerilado, the keck clips are made of "poliacetal" in spanish, i.e. polyacetal/paraformaldehyde which seems to have a lower melting point, 120°C, than the 170°C mentioned in this article for POM. Yet the figure says that the clips are made of POM. Either one of the statements concerning the material of which keck clips are made is wrong, or the statement of a melting point of 170°C is too general.

thread_title:  Concerning melting point of POM and the material of which Keck clips are made 

message: Much of this article seems written as an ad.  Example: "Properties POM is characterized by its high strength, hardness and rigidity..."   How nice. But meaningless to the average person.  If these claims are to remain, examples or comparisons should be given.  For example, how much harder is POM than say; glass? ...Nylon, other competitors, ...etc....   Also, where is the average person likely to touch or know of this stuff?  --68.127.86.60 (talk) 20:21, 3 April 2013 (UTC)
thread_title:  Nice Subjective Attributes 

message: I removed the text in the intro that said it is 'available in all colors', because this sounds like an ad and because it was unsourced. I tried to find a source but could only find vague references to custom colours on vendor websites, none of which unambiguously indicated that ANY colour could be produced. I replaced this with more generic text and linked to a vendor page that demonstrates that it "can be produced in a variety of colors". Active voice would be better, but I could not determine which verb would be appropriate to describe the method by which the material is made coloured (i.e. can it happen during production, or always after? Is this process tinting, or dying, or other?) -- RealGrouchy (talk) 21:37, 12 March 2021 (UTC)
