[6] Its appealing material properties have made it popular among the makers of scale models and theatrical props.
Most standard memory foam has a density of 16–80 kg/m 3 (1 to 5 lb/ft 3). Most bedding, such as topper pads and comfort layers in mattresses, has a density of 48–72 kg/m 3 (3 to 4.5 lb/ft 3). High densities such as 85 kg/m 3 (5.3 lb/ft 3) are used infrequently. The firmness property (hard to soft) of memory foam is used in determining comfort.
Foams are two-phase material systems where a gas is disbursed in a second, non-gaseous material, specifically, in which gas cells are enclosed by a distinct liquid or solid material.

Typically it is made from expanded pellets ('EPE bead') made with use of a blowing agent, followed by expansion into a mold in a steam chest - the process is similar to that used to make expanded polystyrene foam.
Due to the low density of polystyrene foam, it is not economical to collect. However, if the waste material goes through an initial compaction process, the material changes density from typically 30 kg/m 3 to 330 kg/m 3 and becomes a recyclable commodity of high value for producers of recycled plastic pellets. Expanded polystyrene scrap can be ...
