Also do I kneed it to get some of the liquid out or should I just let it sit out the moment i remove it from liquid to let it dry? The dissolving power of p-cymene [212.0 g (100 g solvent)−1] to polystyrene at 50°C compared favorably with those of 2-p-cymenol [156.7 g (100 g solvent)−1], (R)-limonene and its structural isomers [181.7–197.1 g (100 g solvent)−1], and Abies leaf oil [84.7 g (100 g solvent)−1]. It takes very little of the gasoline or other liquid to “melt” the styrofoam. The incredibly lightweight material, used in everything from consumer electronics packaging to food-grade containers, takes a chemical toll on the human body. when solid, re melts at about 104C/220F(seriously this is like easy bake kids oven temperatures! We have only tried with traditional chemical products and the results are good but very toxic and that is not what we are looking for. Styrofoam is made from a common plastic called polystyrene and it mixed with air. Hot glue is one of the worst glues to use on Styrofoam, because, if applied directly to the Styrofoam, it will melt. p-Cymene and polystyrene can be recovered almost quantitatively from the polystyrene solution by simple steam distillation. Here are some important tips. Styrofoam is an ever-present waste material in modern society, being used to package everything from food to futons.

Polysevert uses Cymene to do what im doing with limonene info on the solvent here. My question now is what is the resulting goo? The trademark Styrofoam by Dow Chemical Company is informally used (mainly US & Canada) for all foamed polystyrene products, although strictly it should only be used for "extruded closed-cell" polystyrene foams made by Dow Chemicals. Experiments in mixes of acetone and D'Limonene Cool tool! $2. Should be able to distil out the acetone from the water for reuse. Ethyl, like the alcohol people drink, and acetate, like acetic acid a.k.a. However, since it is a plastic, styrofoam will melt … ‘Maker Goop’ Can be handy for making small plastic parts, castings, or just to make the EPS a flowable product for makers, or for Recyclers which could have the solvents extracted and reused commercially, or burned (as is done in the EU for power. The streets of the capital region are awash in styrofoam. Styrofoam is a massive problem in the developing world. A foam food container is a form of disposable food packaging for various foods and beverages, such as processed instant noodles, raw meat from supermarkets, ice cream from ice cream parlors, cooked food from delicatessens or food stalls, or beverages like "coffee to go". Should I be? This is only a simple starting point guide, most of the molds i made were mostly just proof of concept, I was preparing for the 7th Annual Albuquerque Mini Maker Faire, where i showed off my Styrofoam re-creations and a bunch of my experiments that lead me up to this point, (in the process i tried a lot of other solvents, xylene, toluene, acetone, gasoline, naphtha, lacquer thinner, M.E.K.) Hi!! Thanks for your attention. 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. Might be good for just strictly commercial use, this may also vary by formulation, D-limonene: works great on plain white ps, will dissolve quite a lot per oz, nice smell, not known to be toxic, leaves the ps very clear (sometimes a slight yellowing) virtually no bubbles, long glass transition. cut off chunks and pile them on the things you want it to flow into, and then drop it in your toaster oven, set to 210F the solvent helps lower the melting point of the plastic down from the 250F-300F pure polystyrene, and bake it at 210F for about 30-45 min if there are any bubbles, you can gently pat the surface with a spatula or other poker to get them to pop. ive mostly fixed this by transfering it from the bucket into a cookie sheet and letting it dry out flat until i can flip it. Did you make this project? In the future i want to experiment more with casting LED's into them, as well as adding magnets, trying out some plasticisers such as Butylated rubber particles to make it a more HIPS style plastic. (not connected to seller in any way other than as a satisfied customer). Polystyrene itself is a hydrocarbon, which means it is made up only of carbon and hydrogen atoms bound together. The only problem is that ,once dissolved ,there nothing which you can do except to use it as glue.I am glad that D-limonene can make it into a liquid state ,which allow one to mold it .Styrofoam dissolved in acetone is not workable,I have been doing a study on how to turn it to a liquid state.thanks to this article for providing a solution to my concern. sent you an email reply. https://en.wikipedia.org/wiki/P-Cymene, more on Cymene (thyme/Lavender terpene) https://link.springer.com/article/10.1007/s10086-009-1073-x. im also wanting to try it out with a small desktop injection molding rig too. on Step 4. whoo! you can keep stirring it in to speed things up, or you can just toss it in and snap the lid on and wait for it to all melt. In recycling energy is used to “melt” it down and retain the raw material again instead of it hitting the waste stream. My question now is what is the resulting goo? End result foams and puffs up as it dries. on Step 6. Since Styrofoam is mostly air, you may be surprised by how much (or, in the end, how little) foam will dissolve in the acetone. All the air inside escapes, and it becomes a wet, gooey mess. Or eventually a condensing chamber i can pipe in ther hot distilled acetone? And dries white, one neat thing is its totally not sticky. I have also not investigated only using acetone vapors, perhaps a bucket with a pie tin in it with acetone under it, and ps, and a lid. some spare cookie sheets or even some waxed paper or whatnot to leave things to finish curing on. The average diameter of the styrofoam fibers was 8 µm. And keep in mind that these make stylish spaces for storage, also. https://www.hansen-solubility.com/HSP-science/sol... Looks like 87% d-limonene to 13% Acetone by volume should do the best melt. 7 Cool Ways to Reuse Styrofoam Coolers. Styrofoam is a chemical of petroleum base that is fluffed up like cool whip, when it dissolves in gasoline it changes back to a liquid.
