Foam Boards Properties

Physical, mechanical, thermal, electrical, and optical properties of foam boards

Print

Foam Boards are rigid, lightweight graphic art boards. They are easy to fabricate, can be knife cut, die cut, printed, painted, mounted, laminated, saw cut, and routed. They are widely used for POP displays, kiosks, framing and mounting, and sets and props. Foam boards are an excellent choice for short and long-term use, and can be embossed and debossed without heat for 3D effects.

Foam board is available in a variety of grades and colors. Please ask your Curbell Plastics representative for more specific information about an individual brand.
