Of course, some variables can affect the resistance of plastics: concentration, temperature, length of time, frequency, presence of other chemicals, and more. These ratings reflect plastics tested at ambient temperature. Because the chemical makeup of these plastics is so different from acetone, any reaction is negligible for mechanical properties.
You can expect at least a minor effect they contact acetone. This category indicates that acetone would have a moderate effect on the plastic. On our chemical resistance chart, we just list one: acetal. If it comes into regular contact with acetone, your part will have a limited life.
If acetone comes into contact with the plastics below, you can expect a severe effect, especially at a high concentration and over a long time. There are a variety of times when you may need to melt plastic. For instance, you may want to smooth out a sharp, broken edge to repair a plastic part or you may want to repurpose a piece of plastic to make it into something else, such as when plastic is melted and then turned on a lathe. Whatever the reason, it's easiest to use direct heat or chemicals when melting plastic at home, as these are generally safe and accessible ways of heating.
With some care and the right type of plastic, you can safely melt plastics and give them a whole new life. One easy way to melt plastic is using an oven. Just place the plastic in a heat-proof container and melt it in the oven at degrees Fahrenheit. Open some nearby windows and turn on your oven's fan while the plastic melts to get rid of any toxic fumes. You can also melt plastic using a heat gun.
First, place it on a heat-proof surface, like a metal sheet or concrete block, outside. Turn on your heat gun and apply it to the plastic in slow, sweeping motions. This can take a little while, but be patient and keep the heat gun moving so you don't burn the plastic. For more tips, including how to melt plastic with acetone, read on! Did this summary help you?

Place the plastic in a heat-proof container. In order to melt the plastic in the oven you need a surface that will fit in the oven and will hold the plastic, even when it is melted. It is important to make sure that the plastic will not spill on the oven surfaces if it becomes totally liquid. If it does, it can be difficult to remove.
This temperature will gradually melt the plastic. However, you will need to be patient with the melting. Provide adequate ventilation. Even when melting plastic gradually, there are likely fumes released into the air.
To avoid inhaling them, make sure your windows are open and air is moving through the area. If you have an exhaust fan, turn it on. Also consider wearing a respirator to avoid inhaling any fumes. Watch your plastic as it melts in order to avoid burning. Turn on your oven light and watch it through the window in the door. This will help you avoid burning the plastic, as it should be taken out of the oven right when it has melted and before it smokes or burns. Take the plastic out of the oven.
Use oven mitts to carefully pick up the container the plastic it is in. While the plastic is still hot, you can pour it straight into a mold. If you want to cut it into a new shape later, let it cool in the melting container. Melted plastic can be put into a mold to shape it. You can use a pre-made heat resistant mold or make your own.
If you want a particular shape, it may be best to make your own mold out of wood. Polypropylene and polyethylene are resistant to conventional acids but can be dissolved by super acids. The main reason plastics are resistant to acids is that they are nonpolar materials like oil. This means that it takes a super acid to ionize the atoms to pull it into solution in water. It should take a few minutes for the plastic to melt.
But remember, melting plastics will produce fumes which can be harmful if inhaled. Make sure to melt them in a well ventilated area. The basic idea is to apply heat to the edges being joined in order to melt the plastic until it is liquid enough to blend the edges together.
To glue plastic together, start by selecting the right glue. Find the recycling symbol on the plastic, which will have a number in the middle. The conventional plastics like, PE, PVC, and PS are water-insoluble thermoplastic polymers, as a result vinegar do not dissolve them at ambient conditions.
It will, however, dissolve metal, rock, glass, ceramic. Hydrofluoric acid HF is a solution of hydrogen fluoride in water. Hydrofluoric acid is a highly corrosive acid, capable of dissolving many materials, especially oxides.
When mixing or blending chemicals with sulfuric acid, an exothermic reaction may occur, and the heat of the chemical can cause damage if not properly addressed.
