What makes PA66 filament superior for aggressive deburring and edge-blending applications?

PA66 (Nylon 66) possesses higher tensile strength and superior heat resistance compared to PA6. This robust foundation allows the filaments to be effectively loaded with abrasive grains (such as silicon carbide or aluminum oxide). The combination of the durable PA66 filament and the embedded abrasive creates an aggressive cutting action that quickly removes burrs, flashes, and sharp edges from metal parts after machining or casting.
