Abstract

An extruded matt foil has at least one layer in which glass beads are uniformly distributed in a polymer matrix with at least one fluoropolymer and at least one further layer. The matt foil has a particularly high UV-resistance, a high weathering resistance and excellent mechanical properties. Therefore, the foil is highly suitable for surface-protection of materials such as polyvinyl chloride (PVC) and for use in high-pressure laminates (HPLs).
