Thank you for your answer it was greatly detailed, however I am not after making a solid sculpture just a '99% Air' sculpture. 4 years ago. Acetone melts styrofoam because it is a very good solvent for polystyrene, the material that styrofoam is made from. Now I know Acetone is a great way to melt/dissolve the polystyrene, this is not what I am after, sure if you need to dissolve the polystyrene to remould it then sweet I'll do that.

This would be pretty challenging to do without the right equipment. 'Styrofoam' is actually a polymer of styrene (vinyl benzene --- C6H5-CH=CH2). For instance, rubber cement, a fairly strong, flexible adhesive, often contains both alcohol and acetone. Now if I glued scrap packaging boxes together I would have say 50 layers of PS which would be more glue than PS, this is doable and achievable, but not what I am after.

A cup of acetone … read more . Soybean oil and other vegetable oils, and fats are classified as Lipids. For instance, acetone works well to melt abs plastic, which is a hard plastic that has many common applications. First: Pour ½ cup of acetone into the bowl. I was just hoping I could repeat the initial manufacturing method of steaming/boiling the many pieces of styrene to make it somewhat maluable to form then into a block (I am wanting to try and keep the styrene consistency somewhat unaffected, or if needs to be melted then re-enhanced to reach back to or close to the original consistency). pretty sure limonene (from citrus) does too. Unless were talking caned, but still, you usually heat up the veggies, so another vote for fruit. Amyl acetate will also dissolve styrofoam.

Mark. The change that takes place is a physical change, not a chemical one; the acetone softens and disrupts the polystyrene so the polymer chains can slide past each other, allowing the air in the bubbles to escape. Acetone (nail polish remover) Styrofoam cups. Styrofoam melts when submerged in acetone. It's magical. Which is hot! Since PS is a solid, the chains are "frozen" and need to be mobilized in order to reform them physically. (Please note: I have not tried this one because ether evaporates so fast.

I get plenty of polystyrene come to me in the form of packaging due to online purchases, instead of throwing this out I would like to remould the various pre-fabricated shapes/sizes into blocks and then carve little (or big) sculptures out of them. The DOW is trying to eliminate the use of styrene as it is because it smells so bad and is very toxic hence the company is trying to resort to co-polymerization (adding other monomers along with styrene in the polymerization process). The chemicals given off by melting and/or burning polymers (including stryrofoam) vary with the temperatures, but they present a serious threat to firefighters. Or you can just pour the acetone over the top for the styrofoam. Since Styrofoam is mostly air, you may be surprised by how much (or, in the end, how little) foam will dissolve in the acetone. Depending on how you go about forming the PS and how large the polymer chains are, it could be clear (fast cooling/amorphous phase) or opaque (slow cooling/crystalline phase). 0:40.
