Insulation. Styrofoam insulates much more effectively than plastic, which means your cold drinks stay colder longer and your hot drinks stay hotter. Plastic cups are not recommended for hot drinks, and they do not have the insulation properties of Styrofoam.
Styrofoam is a foam plastic that is made from styrene monomers. It is popular as an insulator in packaging and for food. There are hazardous chemicals in Styrofoam, including styrene and diethylhexyl adipate. When exposed to heat or acids, these chemicals can leach out of the Styrofoam in small amounts. This is partly why Styrofoam is not considered microwave-safe, as the plastic also breaks down easily.
