what is good to weaken plastic/ rubber that is none toxic?

Try heat. (Or wire strippers if it is infact a wire.)

Rubber comes from a tree and plastic comes from oil. Therefore rubber is "natural" and plastic is not.

Probably PVC.....it's pretty inert and resistant to acid or, in your case, base.

to prevent rust/oxidation

Regular Cloth band-aids work better than the plastic kind. My husband is a mechanic and that is the only Band-aid that holds up to the kind on work he does, they are durable.

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.

Any polar, organic, acidic solution would work the best.\n\nThe acid (try 2M sulfuric) will hydrolyze the bonds in the polymer, breaking the foam down into styrene monomers.  The polar organic solvent (try acetone) will then dissolve the monomers (like dissolves like!)

acetone might dissolve the plastic.  it can ruin a synthetic gun stock.

There are some heat treatments or annealing things they do with plastics that may change its strength.

YOU CAN TRY SOME RUBBING ALCHOL ON A RAG, YOU CAN USE WD 40...THAT WORKS GREAT, AND YOU CAN USE THIS STUFF CALLED OOPS, IT COMES IN A SMALL CAN THAT YOU GET AT THE HARDWARE STORE. GOOD LUCK! IF YOU WOULD LIKE TO LOOK UP HELOISE HINTS ON LINE...SHE HAS ALL THE ANSWERS TO HOUSEHOLD TIPS.

If you soak them in a solvent they will soften, but they may also swell a little.  Most rubbers are not resistant to acetone (nail polish remover) so you could try a couple of sample tyres with that or perhaps try paint thinners.  Some vegetable oils will have the same effect.

In the past I have used super glue remover. Seems to work for me.

It Depends on what gains more importance,\n1) If you what it to be rigid & give a good look then ABS will be good,\n2) If you want it to be soft than PP (Polyproplene) is good,\n3) If you what it to be heat resistant & high stength then Bakalite (Thermoset plastic) will be good

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!

If you mean polysesquisiloxane ( a cosmetic silicone ) try Dow Corning or Wacker for industrial quantities. If you are after small quantities, try \n\n www.soaperschoice.com

You can try Muratic Acid ( dilute 4 parts water with 1 part acid )\nMix in a 5 gal bucket , pour on tire marks then scrub with a stiff bristle broom and hose off . That should do it but do not breath the vapors , I recommend wearing a protective mask ( available at your local hardware store ) .

has to be metal, preferably in several sheets not touching each other. Wood and plastic do not stop magnetic field.\n\nThick piece of lead would definitely work, and is completely safe (as long as you do not drop it on your foot and wash your hands afterwards)
