I would've thought it would not be possible to recycle balloon latex because one of the steps of making balloons involves vulcanisation. This changes how the latex polymer cross-linking works. You'd have to reverse that somehow and I think it's widely regarded as irreversible.

Dissolving sounds like it would make the latex unusable afterwards. What about melting with heat? According to this website (answers.com/Q/What_is_the_melting_point_of_latex) the melting point of latex is 250 - 350 F. If that's correct, couldn't you melt the latex down into a mold?

I have an idea, why don't use a q24 to make a mold,( you don't need to break it, using a cork plug to seal it should be enough), that way when the method for making balloons is improved enough you could easily make more.

That could solve the problem of its disappearance from the market.

Seidenki is correct, vulcanization literally changes how the latex acts, and is irreversible, you're literally changing how the latex acts at a molecular level

I was thinking about formers. Could you use a light bulb? perfectly smooth glass, and if you drilled a hole in the screw in part, couldn't you fill it with plaster or something to make it heavy?

Sorry engineer thinking here. There are some big light bulbs...

Old thread but I am still doing this. I have some questions about chemistry of latex, specifically how it's compounded and how to tell what kind I have. Some of the balloons are like 'normal' balloons where others are super soft and deform easily without really returning to shape. I have to use completely different processes for both kinds of latex to get usable balloons.

Also a question regarding surface tension on the formers, ideas for getting coagulant to 'stick' more evenly on more kinds of surfaces. It works well on ABS and aluminum, glass is pretty good, but epoxy is very hit and miss. Usually just beads off. I'm just using the recommended surfactant found on the web, Triton I think, don't know if I should try something different maybe.
