The Different Types of Styrofoam
Before I answer this question, I have to give some background regarding styrofoam. Don't ever think that this particular material is all but the same. Sure. The layman on the street would think that styrofoam have the same structure, purpose, or built. Guilty or not, most of you think of the white, lightweight, foam-like material when this term is being mentioned.
Don't worry. Such a misconception is nothing that you should be ashamed of. In the past, I have the same idea, too.
When I learned about the facts, I was quite surprised.
Polystyrene
One should know, styrofoam have two types. The traditional one is commonly understood in the industry as the "styrofoam" that is made from polystyrene. The latter is a variant of plastic that is formed through the combination of benzene and styrene. Well, if you have a slight hint about these compounds, you already know that they are harmful to human health.
There are some studies that confirmed that containing high levels of these two compounds can result in cancer. They have carcinogenic effects, which is something that automatically spells disaster. Aside from that, they can also harm the reproductive system, too. In short, you don't want to deal with products that contain a lot of polystyrenes.
Keep in mind that styrofoam generates unlikely effects when exposed to heat. When heated for extended periods, the material tends to melt or break. If this is the case, then there's a high possibility that benzene and styrene can be mixed with the food. Therefore, styrofoam should not put in a microwave, especially if you put it on high temperatures. If the heat is just minimal, then styrofoam should be harmful. Otherwise, it is not acceptable.
The "Safer Ones"
Recently, new types of styrofoam have been released commercially. They have a different composition as compared to the traditional polystyrene. However, you can guarantee that they still have the properties of styrofoam that we are all familiar with. The only significant change here is that the use of harmful chemicals is already mitigated.
This particular styrofoam has been designed to address the problem of conventional types of styrofoam. This variant can deal with heat better than its counterpart. When exposed to high temperatures, it doesn't melt, break, or release harmful compounds to the food. To put it simply, this styrofoam should be your choice if you want to maintain the safety levels of your food when microwaving them.
Of course, there's a guarantee that the new version of styrofoam is safe. After all, it has surpassed the standards of the Food and Drugs Administration (DFA) when it comes to chemical leaching. Any styrofoam that has been tested and approved by the FDA possesses suitability for use.
Therefore, to ensure that particular styrofoam is safe to be used in the microwave, just look at its label. Does it have the FDA seal, then you should get it. If not, then feel free to hesitate. Your safety is on the line here.
