Description
Lightweight, laminated panels of foamed polymer (Styrene, Polyethylene, Polyurethane) adhered between one or two outer layers of paper, metal or plastic to produce a rigid structure in a variety of thicknesses, sizes, and densities. Foamboards belong to the family of graphic artboards that can be easily cut, mounted, printed, and laminated. Acid-free foamboards are used for matting and mounting works of art.
Depending on the board, the outer cladding may be adhesive paper, cotton archival paper, white clay coated paper, or a common brown kraft paper. Specialized outer coatings are made with aluminum, polymer sheets and/or fire retardants.
Types of foam used for the interiors are listed below:
| FOAMS | Polymer/foam type | Characteristics | Foamboard examples | Working properties | Risks |
|---|---|---|---|---|---|
| Ethylene vinyl acetate (EVA) | thermoplastic/ closed-cell | frequently used foam sheet with a wide density range; provides good insulation, moisture resistance and can be heat formed; buoyant | Evasote, Sponge Aero Rubber | ||
| Polyester (PET) | thermoplastic/ closed-cell | Lighter weight than PVC, or balsa, but not as strong; moisture resistant and recyclable; higher densities are stiffer and stronger; UV resistant | (McMaster-Carr) | Can be soften and shaped with heat; cut with wood-working tools; tensile strength = 260-320 psi; Max temp=300F | |

Synonyms and Related Terms
cartón pluma (Esp.); plaque de plastique expensé (Fr.); foamboard; foam board; foamcore; mounting board; cushioning; packaging materials
Commercial Products: Foam Core; Artcare; Fome-Cor®; Gatorfoam®
Applications
- packaging; cushioning
- structural panels, partitions; wood replacement; light duty housing
- signage; decoration; advertising; composite layups
- architectural models
- insulation for sound, and temperature; vibration dampening
Collection Risks
Foamboards vary widely in their potential for off-gassing hazardous materials and should be tested prior to use. Boards containing beaded polystyrene may release beads from cut edge.
Environmental Risks
In general, foamboards cannot be recycled, just reused. This is because they are composed of multiple types of inseparable materials, i.e. foam, paper, adhesive, etc. The exceptions are foamboards without surface coverings, such as ... and foamboard with coverings of the same materials, such as....
The area of main concern the the environment is the trash disposal of PVC boards (Sintra, Forex, Komacel, etc.) because PVC breaks down into toxic residues. See Red list of Materials
