The video, uploaded by YouTube channel Let's Melt This, shows acetone — commonly used as nail polish remover — dissolving a Styrofoam cup on a plate. Whatever you do, Styrofoam is like 99% air so you will need a lot of Styrofoam to make a solid sculpture. Start by breaking your block or blocks of Styrofoam in pieces that fit into your glass container. Polystyrene is made from the monomer styrene, an organic compound, which is catalyzed and turns into polystyrene, a solid plastic which is readily soluble in acetone. If the acetone will melt your plastic, the melting will occur on contact. Acetone also instantly melts Styrofoam into a gummy, runny consistency. The chemicals given off by melting and/or burning polymers (including stryrofoam) vary with the temperatures, but they present a serious threat to firefighters. It's magical. Have have an idea but I cannot seem to find an accurate answer, just a load of BS round the bush answers. Furthermore, Aliphatic Hydrocarbons (liquids), e.g. Amines will probably dissolve styrofoam. Amyl acetate will also dissolve styrofoam. I predicted that the more acetone we use the faster it will take Styrofoam to dissolve. Since Styrofoam is mostly air, you may be surprised by how much (or, in the end, how little) foam will dissolve in the acetone. Melt blending or solution casting are the only methods.

Then you might have a puck of PS if it dries properly. Metal bowl or pot. All you need to do is to pour a bit of acetone into a bowl, and place Styrofoam beads, packing peanuts, chunks of foam, or even a Styrofoam cup in the container. Anyone watching it would wonder what had happened to the Styrofoam cup which was dipped in Acetone, nothing but common nail polish remover. 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). 0:40. Second: Slowly lower a Styrofoam cup into the acetone. Report . Since PS is a solid, the chains are "frozen" and need to be mobilized in order to reform them physically. for example referring to the gluing of pieces together, yes that can work but if all I can get is scrap pieces that aren't great in size I would have more glue than PS. 'Styrofoam' is actually a polymer of styrene (vinyl benzene --- C6H5-CH=CH2). Acetone is a handy solvent found in nail polish remover and paint-store denatured alcohol. Besides acetone, what else dissolves styrofoam? The 'foam' bit goes away. Dissolve styrofoam with acetone using tips from this how-to video.

Gluing styrofoam to other surfaces or even other pieces of styrofoam is not a complicated process. So, Styrofoam is a foamed version of polystyrene (PS). Styrofoam (to make it more attractive to children, you can use shaped one: heart, star, square, box etc.) It needs to be pure acetone, not regular nail polish remover. 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. Also, Aromatic Hydrocarbons will also dissolve styrofoam, e.g Toluene (methyl benzene), benzene, etc. Or you can just pour the acetone over the top for the styrofoam. Theoretical mix RA of 3.8 (lower= better) But 25% d'limonene to 75% M.E.K has a theoretical RA of 3.7 . Caution. pretty sure limonene (from citrus) does too.
