Is the extrusion plate the same as the foam board?
Foam plastic plate: plastic foam or plastic sheet, or plastic sheet, foamed, washed or foamed
Extruded board: the polystyrene resin and additives by extrusion process manufacturing have continuous uniform surface and obturator honeycomb structure plate some honeycomb structure is totally void of a plate type structure with obturator insulation materials (150-500Kpa) have the same pressure with low thermal conductivity values (only 0.028W/ M.K) has excellent insulation failure compressive strength compressive properties of 220-500Kpa
