Abstract: The invention relates to a multilayer body comprising at least one substrate layer, a metal layer bonded directly thereto and optionally at least one protective layer atop the metal layer, wherein the substrate layer comprises a composition which is obtained by mixing polycarbonate, talc and a specific wax. It was shown that the multilayer bodies obtained are particularly suitable for use as reflectors and (housing) components for light sources and heat sources and displays.

Abstract: The invention relates to a filler-containing multi-layer structure on the basis of a polycarbonate composition, having a metal layer as a reflective layer and having a balanced property profile of CLTE, CLTE ratio, heat conductivity and lustre. This multi-layer structure can be used, inter alia, for reflectors or as a mirror element in head-up displays. Expanded graphite and burned silicon dioxide are contained as fillers. In the composition provided according to the invention, there is no need for an additional heat sink when implementing the component.

Abstract: The invention relates to a process for producing plastic components, in particular optical lenses or optical light-guides, wherein plastic melt is injected via a sprue (3, 4, 6, 8) into a cavity (1) of a moulding tool shaping the component and additional plastic melt is after-pressed into the cavity (1) for the purpose of compensating a volume contraction of the injected plastic melt due to cooling. The process is characterised in that the plastic melt located in the sprue (3, 4, 6, 8) is kept flowable by means of energy introduced in the region of the sprue until such time as the molten core of the plastic component has solidified in the course of the after-pressing of plastic melt for the purpose of compensating the volume contraction due to cooling (holding-pressure). The invention further relates to an apparatus for implementing the process.
