This is a short and cute video and watching this could be fun for kids. Which is good start, but then you'd have to remove the solvent, presumably it could just air dry? Yes. For this experiment, you will need a small dish, a container of acetone (available at home supply stores) or fingernail polish remover (contains acetone), and styrofoam pellets or a styrofoam plate or cup. Incidentally, these are the major components of what you place in your gas tank. Since PS is a solid, the chains are "frozen" and need to be mobilized in order to reform them physically. Place the container on a flat surface and fill it up with an acetone. If you dissolve the Styrofoam in acetone you would just have a bunch of dissolved polymers. They are triglycerides of high molecular weight fatty acids. Since Styrofoam is mostly air, you may be surprised by how much (or, in the end, how little) foam will dissolve in the acetone. Observe … Styrofoam is an ever-present waste material in modern society, being used to package everything from food to futons. Using one of these may erode your Styrofoam, creating a liquid mess and ruining your project. Then you might have a puck of PS if it dries properly. Craig Beals from BealsScience.com shows how acetone breaks the bonds of styrofoam polystyrene. The 'foam' bit goes away.

Also, Aromatic Hydrocarbons will also dissolve styrofoam, e.g Toluene (methyl benzene), benzene, etc. Just substitute R and R' to get your name of the ketone. Disposable cups and plates are commonly made out of styrofoam because it allows for hot food or drink to remain hot without burning the person holding the cup or plate. Lv 4. Acetone breaks the structure of polystyrene in its expanded form, styrofoam. Mark. 0 0. Melting styrofoam with acetone! Put the cap on the top of the jar, or cover it with a heavy object like a book and let the jar sit for several minutes while the acetone breaks down the styrofoam. And, because styrofoam is mostly pockets of air, when the bonds are broken the air can escape. When acetone is used as a solvent, the expanded polystyrene will easily dissolve and you’ll be left with a liquid acetone/polystyrene solution. "Melt" Styrofoam. Press question mark to learn the rest of the keyboard shortcuts. First, you must select an appropriate glue type that is suitable for creating a bond on the surface without melting the material. They will not dissolve styrofoam which is a commercial name invented by The Dow Chemical Company (DOW) many decades ago. In other words, the polystyrene dissolves in the acetone. It’s also not the easiest thing to deal with as a waste stream, either. Wi… 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). One styrofoam cup; about 3 teaspoons of acetone/nail polish remover (add more if needed) aluminum tray to put underneath; Procedure. Acetone can be found in nail polish remover and is well known for dissolving styrofoam into a melting glob of awesomeness.What do you want to see us melt next? The fun element comes at the later part of the video. However, since it is a plastic, styrofoam will melt at high temperatures. It can rapidly dissolve or eat its way through styrofoam. 0:40. 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. Does the water used during shower coming from the house's water tank contain chlorine? Whatever you do, Styrofoam is like 99% air so you will need a lot of Styrofoam to make a solid sculpture. Fruits are sweeter and take less effort to arrange, generally, so I tend to eat more fruits.

Gluing styrofoam to other surfaces or even other pieces of styrofoam is not a complicated process. Playing next. Amyl acetate will also dissolve styrofoam. For instance, acetone works well to melt abs plastic, which is a hard plastic that has many common applications. Acetone. So, Styrofoam is a foamed version of polystyrene (PS). The chemicals given off by melting and/or burning polymers (including stryrofoam) vary with the temperatures, but they present a serious threat to firefighters. Over the holidays I came across some unusual shaped packing material made from styrofoam. How do you calculate how much room temperature water (23.3°C) will be needed to drop the temperature of warm water from 50°C to 42°C. A scientist from Ukraine shows what happens when styrofoam comes into contact with acetone. In other words, acetone "dissolves" polystyrene. 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. It's magical. Besides acetone, what else dissolves styrofoam? Styrofoam vs Acetone! So, the correct question is: Why does acetone dissolve styrofoam? read more . Acetone is a handy solvent found in nail polish remover and paint-store denatured alcohol. Basically you take molten PS and then blow a volatile blowing agent in order to foam it. Watch the Styrofoam cup slowly shrinks as it touches the acetone. Please do not touch these. What are examples of organic solvents that will dissolve styrofoam, similar to soybean oil ? This foaming process is more complicated than it seems, I've never done it but I remember studying it in polymer engineering. other ketones. Styrofoam is actually a common name for a material called polystyrene, which is a polymer made up of a long chain of molecules. Then, you simply dry the surface of the foam and apply it as evenly as you can, per the directions on the packaging. Remember that polystyrene is made up of many smaller molecules called monostyrene. Then you might have a puck of PS if it dries properly. Acetone also instantly melts Styrofoam into a gummy, runny consistency. Firefighters save dozens from … 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). Amines will probably dissolve styrofoam. Looks like 87% d-limonene to 13% Acetone by volume should do the best melt. Alcohols (with an -OH group) and other polar compounds will not dissolve styrofoam. For instance, rubber cement, a fairly strong, flexible adhesive, often contains both alcohol and acetone. nPentane, nHexane, nHeptane, nOctane. spontaneous combustion - how does it work? I would like to just know if this is the most efficient way, or, Does anyone knows of a method to 'merge/mould/intertwine/reform' two pieces together to make 1 consistent piece of PS?

This short video is about melting a styro cup without fire. Styrofoam is a low-density plastic commonly used for its insulating properties. As the air escapes the volume of the styrofoam … Because Styrofoam is plastic-based, you'll want to avoid using any glues that contain a solvent that can dissolve plastic. Insert craft glue into the hole, then slide in a wooden dowel for the handle. Then take the pieces and push them into the acetone. Footage filmed on October 1 shows the material melt when it is lowered into the liquid, where it becomes an "adhesive mass." Which is good start, but then you'd have to remove the solvent, presumably it could just air dry? This is basically what is done to recycle PS. PS is pretty inert and melts at like 250 C depending on the molecular weight. The Styrofoam will dissolve in the acetone much like sugar dissolves in hot water.
