Polystyrene Sheet White 4 x 8 x .040"- .080"
POLYSTYRENE HI IMPACT WHITE 48 X 96 (#22828)
As a thermoplastic polymer, polystyrene is in a solid (glassy) state at room temperature but flows if heated above about 100 °C, its glass transition temperature. It becomes rigid again when cooled. This temperature behaviour is exploited for extrusion (as in Styrofoam) and also for molding and vacuum forming, since it can be cast into molds with fine detail.
