Heavy Duty Foamboard with permanent pressure sensitive adhesive. Our Heavy Duty Foam Boards are 3/16" thick. They feature a denser polystyrene core with SBS paper board surfaces. SBS is the same material used to make lightweight packaging such as toothpaste boxes and more. The SBS is stronger than the coated papers to make standard foam board and resists dents and warping better than standard foam board.
Coated with a pressure sensitive or 'cold' adhesive
Sticky to the touch, the adhesive is a high-tack permanent adhesive for maximum hold
