Publication number: 20100021699Abstract: 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.Type: ApplicationFiled: June 13, 2007Publication date: January 28, 2010Applicant: PERGO (EUROPE) ABInventors: Nils-Erik Engstrom, Carl-Gustav Ek
