Abstract

The invention relates to a metallic-colored thermoplastic molding material, which contains metal glitter in various admixtures. In addition, the invention relates to a method to manufacture this molding material and its use in molded bodies with openings. No visible formation of flow lines occurs with the use of this molding material, so that the quality of the goods manufactured is improved. For this purpose, it is planned that the percentage by weight of the metal glitter in the thermoplastic molding material lies between six and 15%, wherein the size of the glitter is not in a Gaussian distribution, but the molding material to a large extent contains only equally sized glitter particles in glitter mixtures.
