摘要:
The invention relates to an illumination device comprising at least one light source (1) and at least one scattering element (2), said device having a simple construction and being cost-effective to produce. According to the invention, the scattering element (2) consists of at least one scattering plastic element (2), in which transparent scattering bodies (3) are embedded in a transparent plastic mass (2) and the scattering element (2) extends over at least one or more light sources (1) and is configured as an external housing part (2) of the illumination device.

The aim of said invention is to produce an information unit for technical devices and machines, in particular for vehicle accessories which is readable day and night independently of the angle of view. For this purpose, the visible display elements (6) of said information unit comprises at least one light-diffusing plastic element (4) in which transparent and/or coloured transparent diffusers are inserted into a transparent and/or coloured transparent plastic compound (4).

The present invention relates to an olefinic thermoplastic elastomer composition comprising a rubber component and a polyolefin, characterized in that it further comprises an adhesion promoter system, which in turn has one or a plurality of first adhesion promoters from the group of the wetting adhesion promoters and one or more second adhesion promoters from the group of chemically reactive adhesion connectors.

The invention relates to a metallic-colored thermoplastic molding compound that contains metal tinsel in different admixtures. The invention further relates to a method for producing said molding compound and to its use for shaped bodies that have openings. When the inventive molding compound is used, visible flow marks do not occur so that the quality of the articles so produced is improved. According to the invention, the percentage by weight of metal tinsel in the thermoplastic molding compound ranges between 6 and 15 %, and the size of the tinsel is not normally distributed but the molding compound contains only tinsel particles of substantially the same size even when tinsel mixtures are used.
摘要:
The invention relates to a method for producing a material composite composed of metal and plastic to form a plastic-metal hybrid component, in which method, to improve the adhesion of the metal surface and at least one plastic component, stochastically random macroscopic and/or microscopic undercuts are made by means of short-pulse laser radiation in the metal surface in order to roughen it, these undercuts each being filled at least partially with the at least one plastic component in an injection moulding process such that said plastic component engages into the macroscopic and/or microscopic undercuts, wherein, following the roughening of the metal surface and before and/or during the injection moulding process for the at least one plastic component, at least the roughened surface of the metal is heated to a temperature which, during processing, lies in the range of room temperature up to 100°C above the processing temperature of the plastic.
