good rubber solvent
Hi there!
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.

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.

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.

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
completely

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.

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".

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.

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 masks

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.

I will be trying with Thioglycolate - permanent hair waving disulphide bond braeaker.
I will report on the results.

I've recently learned the hard way, that toluene over 24h does indeed make suba-seal septa swell and soften into sticky messes.

Stamp collectors use toluene to remove glue.

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.

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.

Nonflammable paint strippers can be distilled to get CH2Cl2. They're only around $20 a gallon too.

Tetrachloroethylene is sold as a grease-remover in electronics. I bought a can of it today in Home Depot for 8 dollars.

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.

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.

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.
