The innovation is based on the task of developing a plate that, despite the required elasticity good flexural rigidity and dimensional rigidity in one has a low specific weight.

The object was achieved with a multilayer board made of foam plastic, which consists of a m supporting structure of crosslinked ^ closed cell polyethylene foam, the one or both sides foam with a offenzelügen plastic entire surface connected ,, wherein the open-cell plastic foam optionally "stit a film and / or with a textile covering.

The plate according to the innovation is particularly characterized the low specific weight of the support body made of closed-cell, networked! Polyethylene foam made of, which makes it possible to rub the good and well-known upholstery properties of the soft open-cell plastic foams with which the support structure is covered, an exact dimensional stability and bending stiffness is achieved will. In the case of mattresses, etc., it is advantageous to have the support frame with a different hardness on both sides soft open-cell plastic "foam to connect so." that by turning the plate, the different sleeping habits (soft or hard) are taken into account. Appropriately when using the plate as Upholstery or wadding of the open-cell, soft plastic foam with a textile covering or a film covered, which creates good thermal insulation against the foam plastic. It also protects the textile covering or the film is in accordance with the innovation multi-layer plastic display panel as much as possible against mechanical damage.

The soft, open-cell plastic foam is used ** moderately glued over the entire surface to the support frame made of cross-linked, closed-cell polyethylene foam, or if greater mechanical stresses are to be expected, thermally welded to one another.

The pattern represents a section from the multilayer sheet of foam plastic according to the invention, on the support frame made of cross-linked, closed-cell polyethylene foam on both sides a soft open-cell plastic foam, each with a different Hardness is glued on.
