The invention describes a transparent plastics composite composed of PMMA and TPU with excellent mechanical properties.

Transparent plastic composite

The present invention relates to a rear-end element () for a motor vehicle encompassing an illumination unit () for the illumination of a number plate, where the illumination unit () illuminates the rear side of the number plate and the illumination unit () has a translucent body () and an illuminant (), where the translucent body of the illumination unit () has been introduced by way of the side area () into the rear-end element (). The present invention moreover describes a motor vehicle which encompasses a rear-end element described above.

Rear element for a motor vehicle comprising a lighting unit

The invention relates to a moulding composition and to the mouldings which can be produced therefrom. Due to their good resistance in the hot water cycle test and in the hot-water/isopropanol test, the plastics mouldings have particularly good suitability for the production of sanitary components.

The invention relates to a shaping tool for the injection molding or injection compression of information carrier disc blanks ( ) made of polymethacrylate plastic which is suited as a component of an injection molding or injection compression machine. The shaping tool is comprised of two mold parts ( ), whereby one mold part ( ) contains a bottom part ( ) of a mold with the information data and, together with the second mold part ( ), forms a cavity for the one information carrier blank and one sprue bush ( ) for a sprue piece ( ) in the tool having a concentrically positioned feed orifice ( ). In addition, the tool comprises a impact cylinder ( ) for shearing the sprue piece ( ) and has an ejector pin ( ). The invention is characterized in that the injection gap (SP) between the feed orifice ( ) of the sprue piece ( ) and the information carrier disc blank ( ) is less than 0.3 mm. In addition, the cutting gap (SN) between the edge of the impact cylinder ( ) and the information carrier disc blank ( ) is less than 0.2 mm.

The invention relates to polymer blends, which can be processed like a thermoplastic, whose bulk A) (50 to 90 wt. %) is polymethylmethacrylate or a polymethacrylate resin; and which also contain 5 to 40 wt. % of, as component B), a tough polymer, in particular an ABS polymerizate; and contain 5 to 40 wt. % of, as component C), a polycarbonate or a polyester carbonate. By adding component C), the heat resistance, impact strength and notched impact strength are improved in the known polymethacrylate/ABS blends. With the addition of an impact modifying component D), contained in quantities of 0 to 20 wt. % in the polymer blend, the impact strength and notched impact strength can be further raised. Preferably, recycled polymers can be added as the polymeric mix components.
