Analyzing Torque Fluctuation in High-Fill Flame Retardant Extrusion: Enhancing Gearbox Stability

In the polymer compounding sector, producing high-fill flame retardant (FR) materials—such as reinforced FR-PA6/66 or PBT—places immense stress on the extruder's drive train. Flame retardants, often added as high-volume powders, drastically alter melt rheology and frequently cause torque fluctuation...
