48" x 96" x 1" Natural Gatorfoam Gator Board - 6 pack

This kraft colored natural brown surface and white core gator board is stronger than foamcore, but about the same weight. Gatorfoam has a very ridgid coating which is resistant to moisture, unlike foamcore board which is foam covered with lightweight card. Gatorfoam is not an acid free material, so you should check before using it for items which will be displayed in museums or other permanent archives. Gatorfoam is an extruded polystyrene foam mounting board encased between layers of a melamine and wood fibre veneer. Gatorfoam/Gatorboard has a harder outer surface than other foam core boards and resists warping.
