Does anyone know of a chemical or other substance that can break down polyurethane foam?

hi, \n\nacetone will do the job nicely.\n\nbe careful, though, it essentially is making napalm.\n\nhere is a list of the effects of variuos solvents, though i think it's on bulk polyurethane, not the foam:\nhttp://www.rimnetics.com/rimsolventsheet.htm\n\nanything there that says breaking, collapse or degradation would probably eat the foam up.\n\ncheers!

search polycarbonate+physical properties\ngood luck

You need to try something which dissolves oil but does not attack canvas.  Can you try a chlorinated hydrocarbon?  Carbon tet or trike might to the trick.  Try an obscure corner of the bag first though.

try the local chemist....

alot of bubble wrap or foam?

Polythene bags..\n\nethylene on polymerization will give polythene material..\n\nThats it!

Preparative HPLC should do the trick.  Try a search at these to see if an exact procedure might be on the web.\n\n\nhttp://www.scienceresearch.com/search/\n\nhttp://www.scirus.com/srsapp/

Caramide peroxide...which is stabilized hydrogen peroxide with urea. \n\nIt must have its appropiate surfactant, to make it effective....these are trade secrets, and you won't find much data on theses, but often they use a sorbitan ester.

Ah ha.  Thermite.  Magnesium ribbon would be the usual method to start this reaction.\n\nBe careful with this reaction...

acetates are ionic, and will more easily dissolve in water than an oil. thats your best bet.

I'd sure be cautious with any Methylene Chloride!  It is highly volatile and it is a carcinogen.  Nasty stuff!  I would first try a strong detergent and steam.  Steam will loosen a lot of compounds that you wouldn't expect to respond to heat and water alone.\n\nJohnny

have you tried silicone rubber.  tensile is typically better than 1500 and 55 shore a is average.

It will highly depend on the polymer.  I would think most will not without decomposition.

Well, you'd have to specify what you are trying to dissolve.  Many plastics are soluble in several solvents... N-Methylpyrrolidone being a good one.  Solvents generally do not attack metals, unless they contain water.  I would steer away from an acid or a base.  Can you say what you're thinking of?  If so, email me at connecticutpoet37@yahoo.com

try the site http://vivisimo.com it's a meta search engine\ntype in "energetic polymers" and you will get your results!

You would need hypo. The chemicals involved are too risky to handle without expert supervision.

try ester like-chloramphenicol
