Abrasive wear behavior of different fillers in PP measured by means of a novel injection molding wear apparatus

The aim of this work was to investigate the abrasive wear of test platelets inserted in a novel injection molding wear apparatus with a capillary slit die in regard to the filler amount, type and geometry in the polymer melt processed through the slit. Furthermore the arrangement of the filler material along the slit was considered. We found, that the geometry of the filler has a high influence on the abrasive wear. From all tested filler materials, the long glass fibers induce the highest damage to the surface.
