Abstract 1. A METHOD OF PROCESSING EXPANDABLE PLASTIC MATERIAL PRINCIPALLY OF A POLYSTYRENE COMPOSITION COMPRISING THE STEPS OF: MIXING MICROWAVE ENERGY ABSORBING MATERIAL SELECTED FROM THE GROUP INCLUDING CARBON, GRAPHITE, MAGNETITE, BARIUM TITANATE AND LOSSY FERRITES WITH SAID PLALSTIC MATERIAL, PLACING SAID MIXED PLASTIC AND ADDITIVE MATERIALS IN A MOLD TO PROVIDE THE DESIRED EXPANDED OBJECT CONFIGURATION, HEATING SAID MOLD BY A MOISTURE LADEN ATMOSPHERE TO CAUSE EXPANSION OF SAID MATERIAL WITHIN SAID MOLD, REMOVAL OF SAID EXPANDED FOAMED PLASTIC MATERIAL OBJECT FROM SAID MOLD, RADIATING SAID REMOVED EXPANDED FOAMED PLASTIC MATERIAL OBJECT WITH MICROWAVE ENERGY A SUFFICIENT TIME TO DIFFUSE RESIDUAL INTERSTITIAL MOISTURE TO THE SURFACE, AND SIMULTANEOUSLY CIRCULATING A DRYING MEDIUM OVER SAID OBJECT TO REMOVE SUBSTANTIALLY ALL OF THE SURFACED MOISTURE.
