Oxidized polyethylene wax for masterbatch dispersion

Oxidized polyethylene wax primarily functions as a dispersant in masterbatch
production. By enhancing the uniform distribution of pigment particles within
the carrier resin, it improves the gloss, processability, and dispersion
stability of the final product. ‌
‌Enhancing Dispersion Uniformity：
Oxidized polyethylene wax reduces van der Waals forces and electrostatic
attraction between pigment particles, disrupting agglomerate structures to
facilitate dispersion in the molten state. For instance, inorganic pigments
like carbon black, which tend to aggregate due to high surface energy,
achieve nano-level uniform distribution when oxidized polyethylene wax is
added. ‌
‌Improved Processing Performance：‌
Wax dispersants enhance melt flowability, reduce viscosity, decrease extruder
energy consumption, and boost production efficiency. Simultaneously, their
lubricating effect prevents heat buildup from friction between pigment
particles during processing, avoiding equipment overheating or malfunctions. ‌
‌Improved Product Performance：‌
Uniformly dispersed pigment particles reduce surface defects like color spots
and streaks while enhancing gloss and mechanical properties. For applications
demanding high dispersion quality—such as automotive components and
appliance housings—polyethylene oxide wax prevents stress concentration
issues caused by agglomeration.
