Another issue with using glazed ceramics in the microwave concerns the amount of heat the dish or cup retains. So, if the food temperature isn't going to get above 175 degrees, this shouldn't take it above safe point. An open forum with loose moderation to discuss self … “Standing 20 inches away from a running microwave results in a 100-fold drop in radiation exposure,” she explains. TL:DR - Polystyrene itself shouldn't be an issue in heating food in the microwave. TUL They have electric kettles at just about every store that sells small appliances, including Wally world. level 2 Tumblr. Microwave ovens don't actually work because of friction between molecules. Microwave-safe Styrofoam . There are a lot of concerns when it comes to reheating food in Ziploc bags. However, at raised temepratures depolymerization can occur. Actual source: http://www.health.harvard.edu/healthbeat/HEALTHbeat_081606.htm. Disclaimer - I still wouldn't heat up something in polystyrene. If you aren’t sure, skip it. Be sure to put your food on a plate or other safe container before zapping them in the microwave. It is not listed as microwave safe because it melts at 240 C, a temperature that microwaved foods can easily exceed. The microwave works by creating a rapid motion with molecules, like water. The ceiling temperature of polystyrene is 395C. The first type is traditional styrofoam, which is a product name for products made out of polystyrene. Now, according to the EPA, the chemical styrene has the following effects: Gastrointestinal effects (IE stomachache), peripheral neuropathy (In layman's terms, the nerves outside the brain stop working). I'm pretty sure I'd die too If I were force fed 8 lbs of just about any raw chemical. Not too bad. At lower temperatures, polymers are very highly preferred in most cases, but as temperatures are raised, you can approach the ceiling temperature. EDIT - An average rat weighs somewhere between 267 – 500 grams. This is not the same as friction between molecules. Heat is created through a process called dielectric heating. Just follow the same rule you follow for using other plastic containers in the microwave: Check the label. We all love the convenience of popping up at our favorite restaurant and get your meal to go. I usually heat the food up for about a minute and everythings fine, the container doesn't melt really. Traditional Styrofoam. The exact cooking time may vary, since microwaves all behave somewhat differently. http://www.epa.gov/ttnatw01/hlthef/styrene.html. Basically, raw polystyrene has a max "safe" temperature of 175 Fahrenheit, and starts warping right around 212 Fahrenheit, AKA boiling point, but doesn't have a fixed melting point. If you have no other option to reheat your food, and you get a little styrofoam in your food, the worst that'll happen is an upset stomach. These waves can stimulate molecules in food, … Styrofoam In the Microwave If your container doesn’t have a microwave-safe symbol, it is not recommended to put it in the microwave. Finally, even if your cup does begin to melt (it shouldn't melt but rather soften at temperatures up to the boiling point of water), it will still be full chains of polystyrene melting and not styrene monomers. To help the noodles cook evenly, and check to make sure they're not over-stewing (which can result in over-done noodles without any bite), stop the microwave about half-way … Just follow the same rule you follow for using other plastic containers in the microwave: Check the label. It causes a mild inflammatory response when encapsulated in the body. Contrary to popular belief, some Styrofoam and other polystyrene containers can safely be used in the microwave. Chain scisscion will occur, and monomers can be released. Close 389 PS, polystyrene, Styrofoam, #7 is not safe for the microwave. Luckily, at 200o C (water boils at 100) in an air atomsphere (like in a microwave), only trace amounts of polystyrene were detected (page 114 of the NIST review). I'm 15 years old and have been heating up leftovers in styrofoam containers for many years now, and I do this about every two weeks or more. Microwave your ramen for between three and five minutes. Before we can really get into if it's safe, we need to figure out what Styrofoam actually is. The best I can break it down (pun unintended) is this: Polystyrene itself is basically nontoxic. Just follow the same rule you follow for using other plastic containers in the microwave: Check the label. TIL you're not supposed to heat up the styrofoam cup of noodles in the microwave when cooking because it releases more of the BPA chemical found in styrofoam. That's really creepy. New York: John Wiley & Sons, Inc., 1997. However, the main problem with killing bed bugs by putting them in the microwave is that the size of the cloth might not fit in the microwave. Luckily for everyone who uses plastics on a daily basis, polymers don't carry the same toxicity as their monomers since often times their large molecular weight (thousands of monomers linked together) and general inertness to chemical attack make them safe in general living conditions (Rubber, PVC, Teflon and many nylons are all built from what could be considered ''toxic'' monomers, but are safe for daily use thanks to the magic of polymers). Should I use water to put out a fire in my microwave? Polystyrene (and most high molecular weight polymers) are in no way soluble in water, and even if 50 % of your cup were to melt, unless you are actively trying to consume the molten plastic you will not be absorbing any appreciable amount through the water in your cup. If the microwave doesn’t come with a defrost option, then defrosting can still be done by one’s own calculation. Microwave can kill the adult bed bugs and even the eggs. Press question mark to learn the rest of the keyboard shortcuts, Metallurgical Engineering | Phase Transformations | Steel, http://www.health.harvard.edu/healthbeat/HEALTHbeat_081606.htm. https://www.health.harvard.edu/staying-healthy/microwaving-food-in-plastic-dangerous-or-not. But don't make a habit out of doing that because the long-term effects are pretty unpleasant. I researched this topic and found that styrofoam is a type of plastic and it should not be used when microwaving food because some of the toxic ingredients in styrofoam can get into your food. Or is there something else that makes this a bad idea? Polystyrene doesn’t melt from the heat in the microwave though, it would melt from the heat of it’s contents warming up. According to the link below, it's made of a combination of air and polystyrene, molded into cells and pressed together. Polystyrene is a plastic product that’s made from, among othe… I have always been told to not put styrofoam in the microwave because it can cause cancer. When people say “styrofoam” they usually mean any of the foam-like, lightweight products used to temporarily hold food and drink: pretty simple, right? Sources: Bloomfield, Louis A. ... Also check out the best best microwave and can you microwave styrofoam. New comments cannot be posted and votes cannot be cast. Check the container to see if it says anything about microwaving. http://www.enotes.com/expanded-polystyrene-foam-epf-reference/expanded-polystyrene-foam-epf. Heating food in styrofoam is safe from a chemical/toxicity point of view. It’s important to note that the vast majority of styrofoam containers like coffee cups, styrofoam plates, and take-out containers are probably not microwave-safe. Heating styrofoam in the microwave can cause it to lose it’s shape, or appear to melt. Various additives in polystyrene however could. level 1 Waters112 I'd like to point out that styrene and polystyrene are vastly different substances. Now, getting an actual non-biased answer about when polystyrene melts was harder than I thought it'd be, but here's the answer: http://www.tempo-foam.com/engineering/thin_wall_copolymers/flinthills/eps-rmer2.pdf. The collision between these rapidly moving molecules create frictional heat, first within the liquid water, which is then transferred to the entire food or beverage. The FDA has observed that Styrofoam containers are not safe for your health when used in the microwave for a long time, and they are also unfavorable to the planet. Does Bloomfield reference polystyrene specifically, or just discuss microwaves? Styrofoam containers package fast food, store leftovers from restaurants and wrap a variety of ready-to-eat foods at takeout restaurants. So if you melt 1-2% of your cup into your food, you're getting about 15-80 milligrams of actual polystyrene in your drink. Email. So, why do styrofoam containers melt in the microwave? If you force feed it 24g of styrene thats somewhere between 5 - 10 % of its body weight. I can't attest for any of the possible additives in polystyrene (which could in fact leach into food/water), but up to the boiling point of water polystyrene is not an issue, except for the fact you may have a melted container under your burrito by the time its done heating. However it's pretty hard not to go above that with a microwave since water boils at 212 degrees and can boil in a microwave at around 2 minutes 30 seconds, according to my own (ceramic) teacup and microwave. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. The materials used in containers designed for hot liquids (including Styrofoam) are generally safe in the microwave, unless they get really hot (above boiling temperature for water). I would just cut these out. You. From on-the-go coffee to take-out meals, many products come in polystyrene containers. Is it because the food get's too hot for them? A takeout package is a lot bigger, so you'll probably exceed the exposure limit. Please respond to every thread I ever visit. But the facts are a bit more complicated. ReddIt. Polystyrene consists of styrene and benzene that are regarded as harmful compounds. Most take out containers and clamshells are made of foam for its insulation properties. That being said, NIST has published reviews of polystyrene decomposition products and sure enough, styrene is the most prominent of these chemicals. To make sure your coffee cup or mug won’t overheat in the microwave… Non-related conclusion: The EPA has officially concluded that 50% of rats will die when force-fed 24 grams of styrene. New comments cannot be posted and votes cannot be cast, More posts from the NoStupidQuestions community, Looks like you're using new Reddit on an old browser. Common items made of styrofoam that are microwaved (that probably should not) include coffee cups, takeout containers, disposable plates, and cup noodles. So no smooshing your face against the glass while you wait for your food to … Even if the eggs are exposed to the microwave, they won’t hatch. So the answer to the question can you microwave styrofoam and is it safe is undoubtedly NO! They keep food warm during transport so you don’t have to reheat them. Place your noodles in the microwave, set the timer, and start cooking. It is not inherently FDA-approved, but can be manufactured to be so. This is due to an equilibrium between the rate of polymerization and depolymerization. r/MadeOfStyrofoam: Rest in Peace HooplaHobo, who was one of MadeOfStyrofoams founding fathers. How Things Work: The Physics of Everyday Life. The main component in extruded polystyrene foam is styrene (C8H8). But don't make a habit out of doing that because the long-term effects are pretty unpleasant. Contrary to popular belief, some Styrofoam and other polystyrene containers can safely be used in the microwave.

Press question mark to learn the rest of the keyboard shortcuts. A Google search puts the weight of a polystyrene cup between 1.5 and 4.4 grams, depending on the size and wall thickness. If you really have no choice or needed to, do check first if the container is microwave-safe and even if it is microwave safe, try to keep the cooking time to not more than 30 seconds. The standard symbol can vary, due to the fact that these products are … And yes I know these aren't great food, but just want to let people know that do eat them. The microwaveable symbol looks like a microwave with wavy lines. The site may not work properly if you don't, If you do not update your browser, we suggest you visit, Press J to jump to the feed. In air, the polymer will have already begun charring at this temperature. To sum it all up, it is perhaps safer to not microwave any Styrofoam containers at all. The radiation causes polarised molecules (like water) to rotate and this builds up heat. I like you. At this temperature, the rate of polymeirzationa and depolymerization are equal. That's a major face-palm moment lol. Polystyrene is a polymer, meaning a very long chain of chemically linked single molecules of styrene (just like polyethylene is a very long chain of linked ethylene monomers). Whether it's a carcinogen or not is inconclusive but signs point toward it causing leukemia. At the base level, there are two different types of styrofoam. Polystyrene doesn’t melt from the heat in the microwave. In other words, you have to get polystyrene REALLY hot to cause release much monomer, and it likely would be already burning in the oxygen rich microwave oven environment. This article reviews whether you can microwave styrofoam, if … Ryan Hansen However, starting at 224o C (about 370 F) the polystyrene starts to break down (so don't cook a pot roast in a polystyrene cooler). Conclusion: If the food you microwave doesn't exceed 175 degrees, it'll survive being microwaved in styrofoam. How much are you consuming? Before we delve deeper and answer the question as to whether or not you can microwave Styrofoam, let us first distinguish the two different types of Styrofoam – the traditional Styrofoam or polystyrene and the newer version of Styrofoam.. 1. [â ]blairco 1 point2 points3 points 3 years ago (0 children). Plastic releases chemicals in the food, which then enters the cells of the consumers’ body. 8 lbs of polystyrene, with a density of 1kg/m3, is not far from 4 cubic meters, which looks something like this. Ughh so when they zap the little styrene cup of beans at the local chip shop....? Looks like you're using new Reddit on an old browser. Microwave ovens are kitchen appliances that turn electricity into electromagnetic waves called microwaves. The cup should not be put in the microwave because it can release more of the BPA chemical from the Styrofoam, researchers said." Contrary to popular belief, some Styrofoam and other polystyrene containers can safely be used in the microwave. Just as a rule of thumb for the melting stuff, the Tg(glass transition temperature, not MELTING temperature, polystyrene doesn't really undergo melting in the strict chemical sense it since it is almost totally amorphous, tha 240C Tm on wikipedia is based on the very tiny crystalline content of atactic styrene) of polystyrene is around 100C depending on molecular weight, which is why you can melt some polystyrene containers by heating certain things in them. ram5928 December 5, 2014 at 11:27 am. The only type of styrofoam you should ever microwave is styrofoam that is marked to be microwaveable. This alternative material is constructed using safer materials, lower levels of hazardous chemical compounds, and is designed to remain more stable at higher temperatures. If you let it go longer and melt 10% of the packaging you're getting about 150-440 mg depending on the package, which is right at the upper limit of the EPA's guidelines for short-term exposure according to the graph in the link above.
