In the processing of rigid PVC pipes, Fischer-Tropsch wax is primarily used as an external lubricant. It works by forming an extremely thin lubricating film between the molten PVC and the metal surfaces of the processing equipment, thereby significantly reducing friction and adhesion.

In masterbatch production, Fischer-Tropsch wax primarily serves as a dispersant and processing aid. Its core function is to help evenly disperse additives such as pigments and fillers within the polymer matrix.

Enhanced Dispersion: Fischer-Tropsch wax wets pigment particles, breaks up agglomerates, and ensures uniform and consistent color, delivering excellent performance even under high-viscosity conditions or when using high-impact pigments.
