2. Closed-cell PVC foamboard - Wikipedia

   en.wikipedia.org/wiki/Closed-cell_PVC_foamboard

   Closed-cell PVC foam takes solid shape due to its linear structure. However, due to this structure, it is more brittle than open-celled PVC foam. It is available in densities varying from 3 to 25 pounds per cubic foot (0.048 to 0.400 g/cm 3). [3] It has a low flammability rate. [4]

3. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   For example, a 1-inch layer of closed-cell foam provides about the same insulation factor as 2 inches of open-cell foam. Closed-cell foam is very strong, and structurally reinforces the insulated surface. By contrast, open-cell foam is soft when cured, with little structural strength.

4. Polystyrene - Wikipedia

   en.wikipedia.org/wiki/Polystyrene

   Expanded polystyrene (EPS) is a rigid and tough, closed-cell foam with a normal density range of 11 to 32 kg/m 3. [47] It is usually white and made of pre-expanded polystyrene beads. The manufacturing process for EPS conventionally begins with the creation of small polystyrene beads.

5. Aluminium foam sandwich - Wikipedia

   en.wikipedia.org/wiki/Aluminium_foam_sandwich

   Ex-situ bonding is achieved by gluing face sheets with an aluminium foam by adhesive bonding, brazing or diffusion bonding. Foams used in this method are either closed-cell or open-cell. When a closed-cell foam is used then it is produced from aluminium alloys either by liquid metal route (e.g. Alporas, [3] Cymat [4]) or by powder metallurgy [2 ...

6. Package cushioning - Wikipedia

   en.wikipedia.org/wiki/Package_cushioning

   Foam structures Several types of polymeric foams are used for cushioning, the most common being expanded polystyrene, polypropylene, polyethylene, and polyurethane. These can be molded engineered shapes or sheets which are cut and glued into cushion structures. [5] Convoluted (or finger) foams are sometimes used. [6]

7. Spray foam - Wikipedia

   en.wikipedia.org/wiki/Spray_foam

   Open cell spray polyurethane foam insulation being applied in wall cavities. Open cell insulation can be crushed in your hand and has a lower insulation value. Closed cell is rigid to the touch and each air cell is completely sealed. While closed cell foam has a higher R-value, it is more costly to buy. [9] Medium-density closed-cell spray foam ...
