Talk:Thermosetting polymer

From Wikipedia, the free encyclopedia

Why does network polymer redirect here? Thermoset network polymers are a subclass of network polymers, but there are many example of network polymers that are not thermoset polymers (hydrogels, for example).

How do you blow mold a crosslinked material? All the materials referenced on the blow molding page are linear polymers. —Preceding unsigned comment added by 67.172.156.116 (talk) 03:01, 9 October 2007 (UTC)[reply]


Thermosetting plastics (thermosets) are polymers materials that cure, through the addition of energy, to a stronger form. The energy may be in the form of heat (generally above 200 degrees Celsius), through a chemical reaction


Thermoset is polymer which cures after heating. Polymer which cures after irradiation or chemical reaction (nota bene in thermosets there is also chemical reaction during curing) isn't THERMOset. Marcinj (talk) 11:51, 14 February 2008 (UTC)[reply]

Question on recycling

[edit]

Article states:

This implies that thermosets cannot be recycled, except as filler material.

Is this true, or would it be more accurate to say that they can't be recycled as plastics other than filler material without being subjected to additional chemical processes? Bongomatic (talk) 08:34, 15 April 2008 (UTC)[reply]

As far as I know it is true, because they sort of form unified huge molecules and you can't reprocess that. Federico Grigio, alias Nahraana (talk) 21:44, 16 April 2008 (UTC)[reply]

Are Thermo Plastics Recyclable? —Preceding unsigned comment added by 116.72.224.74 (talk) 08:42, 26 May 2008 (UTC)[reply]

Yes. See thermoplastics (not the same as thermosetting plastic). Federico Grigio, alias Nahraana (talk) 20:31, 27 May 2008 (UTC)[reply]

Question on Examples

[edit]

Acrylics such as PMMA are listed as thermosets, but on the page for PMMA they are described at thermoplastics. Which is true? —Preceding unsigned comment added by 66.71.40.47 (talk) 23:20, 21 March 2011 (UTC)[reply]

I removed it. Wizard191 (talk) 13:26, 25 March 2011 (UTC)[reply]

Irreversible?

[edit]

The BBC reports that a new class of "digestable" thermosets has accidentally been invented. Acid turns these back into their component materials.

So I have to ask: are thermosets whose curing process is reversible not thermosets? Or has the word "irreversible" been used in this article because all previously known thermosets' curing processes could not be reversed? JanCeuleers (talk) 16:42, 17 May 2014 (UTC)[reply]
