Actually Styrofoam is a Dow Chemical registered trade mark for foam insulation and does not refer to all polystyrene so that term is misused. Polystyrene comes in small bead format and then is expanded into shapes like coffee cups, clam shell container at fast food outlets etc. There are also hard polystyrene products, like disposable cutlery, plastic containers like yogurt etc. electronic housing for TVs etc. It can come in clear form too.
The white foam polystyrene can be painted with acrylic paint, but the second you use a solvent based paint on it, it will dissolve.

How does polystyrene dissolves in toluene?
Polystyrene dissolves in toluene due to its non-polar nature and the similar solubility parameters of both substances. The non-polar toluene molecules can penetrate the polystyrene chains, causing the polymer to swell and eventually dissolve.
Why was methanol an appropriate solvent to precipitate polystyrene?
Methanol is used to force polystyrene OUT of solution. So the simple answer is: you can't. But, there is probably an extreme temperature or pressure that allows polystyrene to remain in solution with methanol present.
Is toothpaste non-polar?
Toothpaste is typically a mixture of polar and non-polar substances. The surfactants in toothpaste are usually polar, while other ingredients such as thickeners and abrasives can be non-polar.
Is the following combinations expected to be soluble or insoluble polar solute and non-polar solvent?
A polar solute is expected to be soluble in a non-polar solvent. This is because "like dissolves like" – polar molecules tend to dissolve in polar solvents, and non-polar molecules dissolve in non-polar solvents.
What happen when a non-polar solute is mixed in a non-polar solvent?
the non polar solute gets dissolved as non polar solutes tend to dissolve in non polar solvents than in polar solvents. for eg: benzene(non polar solute) gets dissolved in carbon tetrachloride which is a non polar solvent but not in water because it is a polar solvent.

Why does thermocol dissolve in benzene?
Thermocol is another name for polystyrene (PS), which is a type of plastic. Benzene is an industrial solvent, and it's primary use is to make styrene. The chemical structure of benzene, a non-polar organic hydrocarbon solvent, and of PS is such that benzene will dissolve styrene and polystyrene.
Why doesn't water dissolve styrofoam?
Styrofoam is made of a polymer called polystyrene, which is not soluble in water due to its non-polar molecular structure. Water is a polar molecule, while polystyrene is non-polar, leading to weak intermolecular forces between the two that prevent dissolution.
Is corn starch polar or nonpolar?
Both polystyrene and cornstarch are made of polymers, which are long-chain molecules that have a basic repeating unit. Some polymers are polar (such as cornstarch), while others are non-polar (such as polystyrene). The polar parts of cornstarch are hydroxy (--OH) groups that hang off the main chain. These hydroxy groups interact with water molecules to form hydrogen bonds, and as a result, cornstarch is soluble in water.-Journal of Chemical Education According to this, cornstarch is polar and the source seems pretty credible was the Google entry right under this one so way to look it up!
Will polystyrene dissolve sugar?
No, I don't suppose, because Polystyrene is a not a good solvent for polar compounds like sugar, itself being totally nonpolar.
Is charcoal polar or non polar?
non-polar
Is testosterone polar or non polar?
It is non polar.
What does non polar and polar mean?
Polar contains polar. Non-polar contains nothing.
Is ClO4 polar or non- polar?
ClO4 is polar.
Is C3H6Br2 polar or non polar?
Nonpolar
CF4 polar or non polar?
It is non-polar, covalent.
