Anyone can tell of good rubber solvent/solvents? (Just in case there is misunderstanding, I'm referring to the actual material (vulcanised cautchouc),
not condoms!).
Found out that formaldehyde works, and I remember trementine could damage rubber seriously. Pentane/hexane/heptane are also on my list.
Cheers

Try N-methyl pyrrolidone (NMP), butyrolactone.
Havent tested it, but NMP dissolves PVC flooring, so it might do the job with rubber, too.garage chemist - 21-12-2005 at 09:17
Chloroform is also a good solvent for rubber as I found out accidentally.
If chloroform is not available, dichloromethane could be used as a substitute, the solvent properties of the two are roughly the same.neutrino - 21-12-2005 at 14:46
What exactly are you trying to do here? Are you after a solution of rubber in some solvent or are you just trying to get rid of some pesky rubber in
an annoying place? If you want the latter, nitric acid might be worth a try.stricnine - 22-12-2005 at 03:48
Yeah, acqua regia is my favourite, but I want to partially dissolve rubber to more or less get a solution of it - but agaion not dissolve it

There are hundreds of different kinds of rubber from natural rubber to Kalrez (perfluoroelastomer). The kind of rubber will highly influence the
selection of solvent. Please be more specific.stricnine - 22-12-2005 at 10:20
It is simple rubber: 'ol natural vulcanised latex or SBR = car tyres broken down into chips. There ain´t no fluorine as far as I know. That's why I
mentioned at the beginning "vulcanised caoutchouc".Magpie - 22-12-2005 at 11:53
I missed your reference to cautchouc. I guess I am just too used to questions being asked in English on this forum.
My reference says that "oil, gasoline, kerosene, benzene, toluene, halogenated solvents, and diester lubes" will all attack SBR. I don't know which
would be a good solvent, however.kazaa81 - 22-12-2005 at 13:26
Maybe phosphorous oxychloride will work...
If I remember right, it was used in war first of using blistering agents (or similar) to damage the rubber of gas masksNERV - 22-12-2005 at 22:35
I personally wouldn’t use POCl3 as it is fairly hard to come by, and it’s defiantly not an armature chemist friendly compound. Plus a quick google
search didn’t yield anything about it being able to dissolve rubber although I may be wrong about that.stricnine - 27-12-2005 at 18:05
I will be trying with Thioglycolate - permanent hair waving disulphide bond braeaker.
I will report on the results.
Keep on supporting!!

US patent 4465535

Reports that 1,2-Dichloroethane preps the surface well.

I've recently learned the hard way, that toluene over 24h does indeed make suba-seal septa swell and soften into sticky messes.The WiZard is In - 17-7-2010 at 05:15

Halocarbon solvents like CCl4, CHCl3, CH2Cl2, CH3CCl3, etc., should do the job, although they are mostly more expen$ive and may be liver toxins, and
have largely gone out of favor for damaging the ozone layer when their vapors are released to the atmosphere.Vogelzang - 17-7-2010 at 08:07
Perchloroethylene (tetrachloroethylene) is used as a dry cleaning solvent. How hard is that to get OTC, ie. not from a chemical company? Butyl
acetate is used as a solvent for rubber cement.Melgar - 17-7-2010 at 10:34
Nonflammable paint strippers can be distilled to get CH2Cl2. They're only around $20 a gallon too.redox - 10-6-2011 at 16:10
is there a way to extract elemental sulfur from rubber?
Why would you want to do that? Mr. Wizard - 11-6-2011 at 15:14
Try a search on that poopular search engine using " rubber cement thinner " and see if will give you what you need. It might be best.Random - 13-6-2011 at 00:17

I have rubber, but I odn't have enough sulfur.Dr.Bob - 16-6-2011 at 13:02
It is not possible to extract sulfur from vulcanized rubber, as it is crosslinked chemically to the rubber polymer chains. You can buiy sulfur cheap
at most drugstores or agrocultural supply stores, as it kills fungus well, and is used as "snake repellent".
Toluene is a common solvent for rubber cement, which is a solution of rubber in solvent. Mixtures of Toluene, Xylene, hexanes, and such are all
used. If you want to be able to remove the solvent, like for a glue, that is a good solution. Chloronated solvents also work well, but are very
volatile and more hazardous.
NMP and other high boiling solvents will slowly dissolve rubber and many other materials, but the resultant goo is hard to do anything further with. Panache - 20-6-2011 at 18:28

Care to rephrase that? lolbarley81 - 21-6-2011 at 04:22
I read somewhere that gasoline can be used to make rubber cement, but it was used with "natural rubber". I'm not sure it would dissolve vulcanized
rubber as well or at all.blogfast25 - 23-6-2011 at 06:32
Something seems to have been missed here: the word ‘vulcanised’. Vulcanised rubber (of whatever kind) CANNOT be dissolved in ANYTHING, unless you
devulcanise them first. Rubbers based on sulphur based vulcanisation methods can be devulcanised (the sulphur bearing crosslinks split), but other
types of vulcanisates (like peroxide based systems) resist devulcanisation almost 100 %. But devulcanising sulphur based vulcanisates is messy and
requires chemistry, not mere dissolution.
Vulcanised rubbers belong to the class of ‘thermoset materials’ (like the mother of all: Bakelite) and are essentially one large macromolecule:
all polymer chains being interlinked with each other by means of so-called crosslinks.
Sulphur ‘cured’ rubbers include: NR, IR, IIR, SBR, CR, NBR, most types of EPDM (EPR), polysulphide and a few others. Most other synthetic
elastomers are cured with irreversible means: peroxides and a small army of propriety chemical packages.
Trust me, I was a rubber technologist for about 15 years.
