Is it sold in the US as 'Plexiglas' or 'Plexiglass'? Currently only the double-s version redirects here. Psmith 22:21, 13 Oct 2003 (UTC)
- The brand name is in fact Plexiglas with one s, but both spellings are common. I made a redirect from Plexiglas now so both spellings redirect here. Ed Cormany 22:51, 13 Oct 2003 (UTC)
I understand that glass does not permit transmission of Infra Red. What about Plexiglas?
- It doesn't either. AxelBoldt 18:58, 25 Jul 2004 (UTC)
- That's partially correct. I added a bullet point about this and an external link for more on transmission characteristics. --Ds13 17:24, 27 Jul 2004 (UTC)
Where did the name "perspex" come from? I had always thought it, like "Plexiglas(s)", was a trade name, but the article suggests otherwise. And is "perspex" really the most common name? I've most often heard it called just "acrylic", or PMMA (polymethyl methacrylate, I believe) in organic chem. — Danc 11:37, 10 Jul 2004 (UTC)
Perspex is a trademark just like plexiglas, so I moved this article to the more neutral title polymethyl methacrylate. AxelBoldt 18:58, 25 Jul 2004 (UTC)
"PMMA does not shiver". What does this mean? Graham 00:09, 26 Jul 2004 (UTC)
- It doesn't break or split into small pieces. AxelBoldt 21:47, 22 Sep 2004 (UTC)
- Isn't that "shatter"? I've changed it accordingly. sjorford 14:41, 23 Sep 2004 (UTC)
