What is polystyrene foam made from?
Polystyrene foam is kind of plastic, a polymer made of (an inter-linked network
of) styrene molecules. Styrene is a compound composed of carbon and
hydrogen. When manufactured as an insulating material, the liquid form
of the polymer is "blown" into a foam by in-situ generation of a large
number of VERY tiny bubbles of gas. The polymer and the entrapped gas
interfere with heat flow through the material. Thus, its insulating
