Also be aware that most Polyurethane foams and model boards cause cure inhibition with many epoxy based pre-pregs when cured at elevated temperature.

Look for expanded polystyrene, that is what your typical white Styrofoam is. You could also use extruded polystyrene if you aren't planning on melting the foam out with acetone.
