During PVC processing (such as extrusion, calendering, and injection molding), the molten PVC material becomes highly viscous due to heat and mechanical shear forces, readily adhering to the metal surfaces of processing equipment (such as screws, barrels, and molds). This leads to increased energy consumption, reduced production efficiency, rough product surfaces, and even decomposition.
As an external lubricant, Fischer-Tropsch wax functions through the following mechanisms:
Migration and spreading: During PVC plasticization, Fischer-Tropsch wax migrates from the PVC mixture interior to the melt surface.
