Beschreibung
Zusammenfassung:	The invention relates to a plastic layered composite, in particular for vehicle glazing. The composite consists of at least three layers, the two outer layers consisting of a transparent poly(methyl methacrylate) (PMMA) and the inner layer consisting of a thermoplastic polyurethane (TPU). The plastic layered composite passes the ECE R43 ball impact test and has improved acoustic properties compared to prior art plastic composites of the same dimensions.
