Abstract:
The present paper discusses about a glossy polypropylene composition which can replace ABS and PC-ABS in the aesthetic interior and exterior bezels of a car with good stiffness and high flow. High Melt flow index of this composition minimizes the number of gate locations thereby drastically improving the aesthetics. Usage of Special Additives, and High Aspect ratio talc reduced the density of this composition as compared to a conventional PP compound. The combined benefits of lower weight, adequate stiffness, good gloss, scratch resistance and weathering resistance in the unpainted form makes this composition attractive for Interior and exterior aesthetic bezels. Again, this composition is cost-effective thereby reducing the part costs of interior and exterior bezels significantly.
