and the Polystyrene will turn into a runny goo when it touches the solvent. Styrofoam is made from a common plastic called polystyrene and it mixed with air. It can be molded or used as a glue or sealant. Or eventually a condensing chamber i can pipe in ther hot distilled acetone? When polystyrene is sent to the landfill, it is quickly covered and this process deprives it of water and oxygen, which would normally help it to break down. Uses include protective packaging (such as packing peanuts and in the jewel cases used for storage of optical discs such as CDs and occasionally DVDs), containers, lids, bottles, trays, tumblers, disposable cutlery and in the making of models. Can't recall if they dissolve in acetone/limonene,) or distil off and recover the acetone, and see if we can do it again. Does kneeding cause more bubbles? What most people refer to as “Styrofoam” is simply generic expanded polystyrene foam, often used for things like coffee cups, food trays, coolers and different types of packaging material. If left out to dry, it gets hard again, but not like before, without the air - it resembels plastic." I am from Chile and with my thesis group we are trying to do something about the EPS that is polluting all the coasts in the south of my country. 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. All the air inside escapes, and it becomes a wet, gooey mess. We melted styrofoam with nail polish remover, 100% acetone. Ethyl, like the alcohol people drink, and acetate, like acetic acid a.k.a. (which may be useful for some resuses). (unless i can buy some expired or perhaps cheaper grade of the stuff since i'm not using it for perfume or food use. Here is a instructable about using just acetone i think i ran into early on in my research, and is totally worth a credit. Question Styrofoam is a low-density plastic commonly used for its insulating properties. Thank You. It does not naturally degrade and will last for years. Dec 12, 2013 - This is a guide about uses for Styrofoam coolers. Polystyrene is also used to make drinking cups and food containers – the hard plastic ones and also the soft foamy ones. i have found the EPS and limonene will float on water, so you can pour several cups of water in, to the bucket first. EPS (Expanded Polystyrene) foam. 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". While it is a goo is it is very sticky and can be used as a glue or sealant. I'm curious about a need for a lid for the bucket used to melt the EPS. Thanks for your attention. Common packaging styrofoam is actually puffed polystyrene, the same polymer that’s used to make things like CD cases and plastic model parts. 'Melting' the EPS, starts with breaking it up into chunks that you can put into your bucket, and then simply adding a few ounces of D-limonene solvent to the bucket and then start feeding EPS into it and let it dissolve in the process the gasses in the foam will bubble out. not very smelly, but i use toaster oven on a back porch. The incredibly lightweight material, used in everything from consumer electronics packaging to food-grade containers, takes a chemical toll on the human body. Many possibilities here. Cons, very long dry time. i suspect if i could do heat and vacuum perhaps, but it felt like the drying time was about the same or slower. (feels kinda like how dice feel). Styrofoam is a very good insulator, and it can be used to insulate pet houses, greenhouses, and other outdoor buildings. https://sites.uci.edu/chem52labs/files/2016/10/M52LA_Exp5_F16UP2.pdf. link to ebay seller of good quality 99% pure limonene i used. Is Gorilla Glue safe for Styrofoam? When you mix Styrofoam (extruded polystyrene) with gasoline or acetone, the Styrofoam breaks down. 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. 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. (not connected to seller in any way other than as a satisfied customer). Carrier, a term for something like a solvent, may be what im needing for the end reprocessing, folks are suggesting toluline, but, in the process im hearing about making conductive ps mixes, using toluene as the carrier. How It Works . although i hear there is a terpene in lavender oil that works on eps just about the same. (fewer bubbles in more thick/dry stock). This EPS comes from the fishing industry and the buoys they use in mussels culture. It is best to use Styrofoam egg crates for this purpose because there is less chance of the wax absorbing into the pores of the mold. my current work involve adding some water to the bucket, to allow the PS and limonine to float on it, which lets it deal with more of the dust and dirt and other dirty waste streams. Yes. When acetone is used as a solvent, the expanded polystyrene will easily dissolve and you’ll be left with a liquid acetone/polystyrene solution. I’ve never really seen any melt even with very hot liquid in them. A cup of acetone is enough to dissolve an entire bean bag's worth of styrofoam beads. Styrofoam is a massive problem in the developing world. I hear lavender oil can also work. Because I tried to find it in Chile but haven't been lucky at all. so a little goes a long way, although more solvent melts the foam faster, but then you have more solvent to remove later. However, the high flammability of the product gives many people pause, as using it in a home or office could have disastrous consequences in the case of fire. but i do hear you need a fair amount of peels/mint to make much limonene. Common polystyrene products include disposable razors, plastic yogurt containers, plastic mailers, and CD jewel cases. I'll be playing around with this for sure. It can be molded and formed. Our city has no program that accepts EPS, and so I looked into some experiments with it, and in the process come up with a 'Easy' technique to Recycle EPS (Expanded Polystyrene Foam) not only reducing its size, but also making it into something usable/useful (im calling it “Maker Goop” for now). The end result was a sticky ball of wet ps. Common packaging styrofoam is actually puffed polystyrene, the same polymer that’s used to make things like CD cases and plastic model parts. One of Styrofoam's most popular uses is as a construction material. And I really look forward to seeing what people do with their own nearly free 'Maker Goop'! Casts with relatively few bubbles*http://katu.com/news/local/tigard-company-plans-to-recycle-tons-of-hard-to-recycle-styrofoam-plastics. dirt falls out to the bottom and can be dumped/composted. My concern was pressure from the gasses released. Is it recyclable? I've not really worked with water crashed out eps much yet, did it two times and all, may try baking it after drying it to see if it will melt back into a puck. foam though, so be sure to grab one that is specified for foam or foamboard (such as one of the ones listed above) when using it. 8 months ago Below are some notes on my experiments on found on Degasifying the EPS (EPS is 90-99% empty space, and 1%-10% Polystyrene. The Great Plastic Patch in the pacific ocean features three million tons of plastic debris floating in an area larger than Texas. Is there a reason for the lid or is it just to keep everything clean? The Process of Styrofoam Recycling . Limonene sadly is not water absorbable so not sure how mixes of acetone/limonene will work, and results of drying lomonine under water have lead to very milky results and super slow drying time. Or 21% Xyline to 79% acetone gets us down to ra of 3.2 which is the best i've pulled from the above table. Question Did you make this project? $2. If left out to dry, it gets hard again, but not like before, without the air – it resembles hard plastic. As those melted surfaces come into contact with each other and solidify, they do form a strong, though somewhat deformed joint. There shouldn’t be any gases released which are any different from the vapours off of the original gasoline. And relatively expensive Pros, not known to be toxic, nice smell, good clean results, not much shrinkage, re-meltable and flows well, stays glassy. One has been working with mixed/dirty polystyrene/eps including drink cups, and paper plates, and togo boxes. Toaster oven, or possibly even an old ezbake oven or dehydrator may work, (only needs about 200F-250F, possible to do this with an oven or other heat sources.) I have not tried, but i did a google search and there are a few youtube videos, and a good number of research papers, looks like you may need a good source of citrus peels, (perhaps you have a nearby juice bar or orange/grapefruit juice making company, and see if you can get them to give you the leftover rinds/peels. The styrofoam was melted by using acetone and the produced fibers were varied in diameter. 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. this not only allows the eps to sink a bit deeper into the limonene, decreasing the solvent needed, but also the water gives food particles and other contaminants a place to settle out into, this plus the layer of limonene/polystyrene on top keeps it from smelling, and the end result eps is a little more easy to get out of the bucket because its a rubbery layer on top of the water. End result foams and puffs up as it dries. One other thing that keeps me from doing a larger scale trial with lavender essential oils. Since Styrofoam is mostly air, you may be surprised by how much (or, in the end, how little) foam will dissolve in the acetone. Medium . Does Gorilla Glue eat Styrofoam? ‘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. I want to know more about D-Limonene and if you have used it with dirty EPS, is it a 100% natural product, what kind of product do you imagine we could do with it to contribute the local communities that are being affected by this problem? Next time heat the soup in a glass or ceramic container or microwave safe cookware. Since Styrofoam lacks the moisture the glue needs to become active, moisture must be added along with the glue. brittle, but better with the wood to help. ) Hot glue is one of the worst glues to use on Styrofoam, because, if applied directly to the Styrofoam, it will melt. yes. here is a pretty good paper on it. I had a bit of the soup and then got scared. I have been doing research on this topic for a quite a while now .95% of people are concentrating in the fact that Styrofoam dissolve in Acetone. "When you mix Styrofoam (extruded polystyrene) with gasoline, the Styrofoam breaks down. Melt away the Styrofoam beads that are visible in most white Styrofoam with a hot air gun. Im suspecting this version will still contain a fair amount of solvent, and may still take some time to dry End result was fairly white and milky with teeny bubbles, workable. If you can't find this product, you could dissolve styrofoam in gasoline just as easily. vinegar. molds (steel or silicone ) 2 years ago. However, since it is a plastic, styrofoam will melt … It takes very little of the gasoline or other liquid to “melt” the styrofoam. It takes at least 500 years to decompose.
