KUNSTSTOFFORMTEILE MIT EINER MIT ANORGANISCHEN FÜLLSTOFFEN GEFÜLLTEN KUNSTSTOFFMATRIX |
| 摘要 |
To improve the resistance to scratching of plastic molded articles comprising a polymer matrix filled with inorganic fillers, the filler content being 50 to 90% by weight in relation to the filled matrix, it is suggested that the filler comprise two filler fractions (a) and (b), wherein the filler fraction (a) has a particle size distribution with 98% by weight of the particles having a particle size </=150 mu m and is distributed essentially uniformly in the polymer matrix, and wherein the filler fraction (b) comprises particles having a particle size of approximately 300 mu m to approximately 3000 mu m, wherein the proportion of the filler fraction (b) is approximately 1 to 35% by weight of the total filler content, and wherein the proportion of the filler fraction (b) in an outer surface layer of the molded article is enriched to at least 30% by weight in relation to the total mass of the filled matrix. |
