  • Patent number: 9713915
    Abstract: The invention relates to at least partly transparent or translucent molded plastic parts for producing noise protection walls, facade components, and glazings which ensure effective bird protection. In particular, the invention relates to molded plastic parts comprising g) at least one substrate layer (matrix/base layer) containing at least one thermoplastic polymer, wherein the substrate layer comprises a base layer and a coextrusion layer adjoining said base layer, said coextrusion layer comprising at least one IR absorber; a) optionally at least one cover layer on at least one face of the substrate layer; and b) optionally a primer or an intermediate layer between the layers a) and b). The invention is characterized in that the molded plastic part has markings in the substrate layer, said markings reducing the transparency of the molded part in the wavelength range of 380 to 780 nm in the marked regions.
