Foam is produced artificially and a distinction is made between 4 types of foam. With open-cell foam, the walls between the individual cells are not closed and the foam can absorb various liquids. In closed-cell foam, the cell walls are closed and the mixed-cell foam contains both open-cell and closed-cell foam. Integral foams have a closed outer skin, which is very thick, on the one hand, and a cellular core, on the other. The density of the integral foams decreases the closer the cellular core comes. foam can be compressed by pressure, the volume decreases. Other properties of the foam are the extremely low density and the ability to conduct heat, although the foam is only partially solid. For this reason it is also used for thermal insulation. In addition, foams have almost no internal stress. One advantage of foam is that the costs for both processing and machining are minimal. In addition, foam is characterized by a very low dead weight. Foam can be produced in a wide variety of thicknesses, densities and designs. Another property of foam is its elasticity. foam is often used as a protective packaging because it absorbs shocks and is very light. Foam is also used to fill cushions. Many mattresses are also made of foam.
