The core advantage of oxidized polyethylene wax in PVC processing lies in its excellent compatibility brought by its molecular polar groups. It can balance internal and external lubrication, significantly promote plasticization, and enhance filler dispersion and product surface quality.
Rigid PVC pipes/profiles: Leverage its plasticizing and balanced lubricating properties to enhance extrusion efficiency and dimensional stability.
Highly filled PVC products: The higher the acid value, the stronger the internal lubrication, which accelerates plasticization and improves filler dispersion.
Transparent/thin-walled products: Avoid precipitation haze to ensure transparency and mold release integrity.
Foamed PVC: Regulate melt strength to enhance cell uniformity and surface flatness.
