Insert craft glue into the hole, then slide in a wooden dowel for the handle. 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). Yes. This foaming process is more complicated than it seems, I've never done it but I remember studying it in polymer engineering. 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. Then wait one to five minutes for some of the acetone to evaporate. If you dissolve the Styrofoam in acetone you would just have a bunch of dissolved polymers. Also, your recast Styrofoam may not be white and it will be like 100x harder. If ice is less dense than liquid water, shouldn’t it behave as a gas? It’s also not the easiest thing to deal with as a waste stream, either. Amyl acetate will also dissolve styrofoam. last year | 40 views. Place the container on a flat surface and fill it up with an acetone. Report . Styrofoam melts when submerged in acetone.
