External Lubrication: Micronized wax has low compatibility with polymers and easily migrates to the interface between the melt and the metal mold, forming a barrier layer that reduces frictional heat, prevents mold sticking, and improves the smoothness of demolding.
Internal Lubrication: Some modified micronized wax exhibit a certain degree of compatibility with resins. They can insert themselves between polymer chains to weaken intermolecular forces, thereby reducing melt viscosity and improving plasticization.
Dispersion Aid: Their ultrafine particle size allows them to uniformly coat pigments or fillers, preventing agglomeration and improving the dispersion uniformity of color masterbatches or filled systems.
