    摘要: The invention relates to a plastics laminate in particular for vehicle glazing. The composite is composed of at least three layers, where the two exterior layers are composed of a transparent polymethyl (meth)acrylate (PMMA) and the internal layer is composed of a thermoplastic polyurethane (TPU). The plastics laminate passes the ECE R43 falling-ball test and has better acoustic properties than prior-art plastics composites of the same size.
