Abstract
The invention relates to a decorative panel, in particular a floor, ceiling, building or wall panel, and a process and extrusion line for producing such decorative panel. The panel comprises at least one core layer and at least one decorative top layer, wherein at least one core layer comprises at least one structural core component and at least one balancing core component, wherein at least one structural core component comprises at least one mineral filler and at least one first polymeric composition and wherein at least one balancing core component comprises at least one second polymeric composition.
Claims19
A decorative floor, ceiling, building or wall panel, comprising:
- at least one core layer;
- and
- at least one decorative top layer;
- wherein the at least one core layer comprises at least one structural core component and at least one balancing core component, wherein the at least one structural core component comprises at least one mineral filler and at least one first polymeric composition and wherein the at least one balancing core component comprises at least one second polymeric composition, wherein the at least one first polymeric composition and/or the at least one second polymeric composition comprises at least one semi-crystalline thermoplastic polymer, and wherein the at least one balancing core component has a Shore D hardness which is in the range of 3-35% higher than the Shore D hardness of the at least one structural core component.
A decorative floor, ceiling building or wall panel, comprising:
- at least one core laver;
- and
- at least one decorative top layer;
- wherein the at least one core layer comprises at least one structural core component and at least one balancing core component,
- wherein the at least one structural core component comprises at least one mineral filler and at least one first polymeric composition and wherein the at least one balancing core component comprises at least one second polymeric composition, wherein the at least one balancing core component has a Shore D hardness which is in the range of 3-35% higher than the Shore D hardness of the at least one structural core component,
- wherein the at least one first polymeric composition comprises at least one plastomeric additive, and
- wherein the at least one plastomeric additive is a copolymer of ethylene and at least one a semi-crystalline thermoplastic polymer.
A decorative floor, ceiling, building or wall panel, comprising:
- at least one core layer;
- and
- at least one decorative top layer;
- wherein the at least one core layer comprises at least one structural core component and at least one balancing core component,
- wherein the at least one structural core component comprises at least one mineral filler and at least one first polymeric composition and wherein the at least one balancing core component comprises at least one second polymeric composition, wherein the at least one balancing core component has a crystallinity which is in the range of 3-35% higher than the crystallinity of the at least one structural core component.
