It is made of polystyrene foam plastics processed through compounding, mold pressing, foaming and shaping. As polystyrene is a thermoplastic which can be melted and then cooled without degradation, it is used with 3D printers. Water uptake vs. time for EPS boards of a range of densities, normalised in terms of the water uptake at 28 days. General-purpose polystyrene is clear, hard, and rather brittle. Polystyrene is available in different forms depending upon the application where it is to be used. He covers everything within Plastics manufacturing and processing. The grafting takes place when some of the radicals start reacting to double bonds of the polybutadiene.
