Acrylics

If you insert a section called "Acrylic" in the article, then it might cause some confusion. Acrylic is a wide range of polymers being synthesized from derivatives of acrylic acid, methacrylic acid and similar compounds. PMMA is only one example, but admittedly a very indicative one for thermoplastics. However, acrylic polymers are definitely not limited only to PMMA. PAN would be another example for a thermoplastic although it does not melt under normal conditions (only at heat rates above 50 K/min to temperatures above 300 °C). On the other side, acrylic resins have a huge variety in the field of thermosets (which cannot be melted or reformed after curing anymore). --2003:53:A011:0:0:0:0:8 (talk) 11:15, 27 October 2016 (UTC)[reply]

Help?

Perhaps this page should have at least links to pages that are about moulding processes? I think this page definetly needs help. It has a lot of very scientific information, but it doesn't make much sense to someone like me researching a school project. I am a lemon 02:20, 26 May 2007 (UTC)[reply]

What are plastics used to make?

Should double double carbon bonds actually be double carbon-carbon bonds? 84.92.54.192 00:58, 10 January 2007 (UTC) what on earthim a nob 22Bold text à[reply]

Discussion a mess

]this dicussion is uberly shocking. it does not meet wikipedias standards Unsigned

Did my best to tidy it up. Hope it's looking better now. I am a lemon 04:14, 8 August 2007 (UTC)[reply]

The article as written is a great summary of physicl chemistry, with a great list of resin types; what seems to be missing is some indicatin of the pervasive impact of commodity themoplastics in our world, eg, I couldn't find current production figures, but in 2001 polyethylene alone was > 10 billion pounds per year. I also wonder if the list at the bottom could be made into table, with chemical structures and asome brief notes - or is that for the seperate articles. in any event, a great start.Cinnamon colbert (talk) 04:19, 23 January 2008 (UTC)[reply]

Table of Thermoplastics

In the Table of Thermoplastics, the melting point is not generally useful; the softening temperature would be better (formally this is the Glass transition temperature, and it determines at what temperature the plastic starts to lose its form). Two other useful columns would be indications of strength and hardness (e.g. poor, fair, good, excellent).

T_p was added; I'm interested in adding forming temperature, which is useful for those engaged in thermoforming (which should be added to See Also). It's associated with T_p, where forming temp is usually conveyed as a range and I believe T_p is usually given as the midpoint in that range (researching further). There are physical measurements of strength and hardness; not sure the subjective indicators (poor, fair, good, excellent) are as appropriate. I'm reworking this awful table.Sushinut (talk) 18:19, 30 January 2010 (UTC)[reply]

Thermosetplastics

So thermosetting plastics cannot be remoulded once they have been heated into a shape while thermoplastics can? —Preceding unsigned comment added by 04alexpeac (talk • contribs) 16:09, 31 May 2009 (UTC)[reply]

Aren't Polyurethanes thermosets? PU is listed in the table of thermoplastics. — Preceding unsigned comment added by 199.73.74.5 (talk) 16:30, 22 March 2012 (UTC)[reply]

Cleaning up the page to make it more accessible

I'll be editing the page so it is easier for casual visitors to understand. I'll try to preserve all information. Please reply here or on my talk page before reverting any edits. Thanks! Rgambord (talk) 03:40, 29 June 2012 (UTC)[reply]

Indented line

Much of the theory section belongs on the general plastics page. Rgambord (talk) 05:05, 29 June 2012 (UTC)[reply]

Will Magnesium Chloride (de-icer) eat through or ruin the Thermoplastic membrane on my roof???

I need to clear 2 sections of roof free of ice to get ready for some major duct construction. There is a lot of Ice buildup and I was wondering if I use Magnesium Chloride de-icer to help me get rid of some of this will it ruin the roof membrane?? please help??? — Preceding unsigned comment added by 67.42.72.138 (talk) 15:06, 23 January 2013 (UTC)[reply]

I helped write the bulk of this article

What in the fucking fuckity fuck did you fuckers do while I was gone? Fuck this thing is now a useless fucking mess and a disgrace to wikipedia. 63.152.94.185 (talk) 00:14, 1 October 2013 (UTC)[reply]

Calm down, I'm sure any long-standing changes weren't malicious. Not the best article on the project, but this thing is a collaborative process. The last version I edited was this one, and it has gone down hill since then. Which version in the history was yours? We could copyedit some things out - if you are, or know, someone well-versed in the topic, some references to get rid of that tag would help too. —Vanderdecken∴∫ξ φ 14:52, 2 October 2013 (UTC)[reply]

They basically have turned it into a help:categories page. Just revert to the last good edit, because this page is an unstructured mess. I was going to refer to it to look up some polymer data, but had to look elsewhere. Malicious or not, the path to hell is paved with good intentions (of idiots and their kin). 63.152.94.185 (talk) 03:08, 5 October 2013 (UTC)[reply]

I have reverted this change, as it represents no improvement whatsoever. the table is largely empty without data, and a mere list of specific polymers without explanation is not very useful. Much more useful was the general description of the classes of thermoplastics. Language-wise it also was a disaster, phrases like "The literature on thermoplastics is huge, and can be quite confusing" have no place in an encyclopedia. Surely, the audience would not be very interested in knowing the author felt confused. If there is useful information in the old version, then please add to the current article in a constructive manner. Kbrose (talk) 18:39, 6 October 2013 (UTC)[reply]

Chemically Inert

I feel that teflon should not be described as chemically inert, perhaps worded something like "rather unreactive with most materials and under most conditions." The only chemically inert substance known is helium. — Preceding unsigned comment added by Grossdm (talk • contribs) 03:52, 1 March 2014 (UTC)[reply]

XLPE is crosslinked and therefore a thermoset

Although this is a subset of Polyester, this article is about thermoplastics and this section is for examples of thermoplastics. This should be removed from this description or noted as an exception. Can I get confirmation from a Materials expert? Wmcleod (talk) 04:08, 27 November 2014 (UTC)[reply]

Bogus link in Reference section: lgschemistry.org.uk

I don't know what this link led to before (http://www.lgschemistry.org.uk/PDF/Thermosoftening_and_thermosetting_plastics.pdf), but there is no PDF on that page. In general, the listings at that URL are now ad links to dating sites and vendors of plastics. This should be removed. — Preceding unsigned comment added by 75.34.99.236 (talk) 19:05, 31 May 2015 (UTC)[reply]
