  • Publication number: 20100021699
    Abstract: A decorative laminate, comprising an upper decorative layer and a carrying core. The upper side of the core is provided with the decorative layer and the lower side of the core is provided with a balance layer. The balance layer has the purpose of preventing warping of said decorative laminate and at the same time has the purpose of acoustic dampening. The balance layer comprises a polymer and cellulose said balance layer having a density in the range 30-300 kg/m3. A predetermined area portion of the balance layer is compressed so that the density is increased by a factor of 1.3 or more. Said increased density does not exceed the density 1100 kg/m3. The balance layer thereby forms at least one low density area and at least one high density area.
