How to Choose PE WAX

Introduction

Polyethylene wax (PE WAX) is a high-molecular-weight processing aid widely used in hot-melt adhesives, PVC, masterbatches, rubber, inks, paints, and fillers. Different grades of PE WAX possess distinct dropping points, viscosities, and physical forms, which directly affect processing behavior, lubricity, and thermal stability in formulations. Therefore, selecting the right PE WAX is not merely about “adding a lubricant”—it is key to determining whether a formulation will be smooth and stable.

What is Dropping Point?

PE WAX dropping point is usually represented by “Dropping Point”, indicating the temperature at which it melts into a liquid state. It affects:

  • Whether the processing temperature is sufficient to fully melt/plasticize the wax

  • The timing and release of the lubricating effect

What is Softening Point?

Softening point indicates the temperature at which the wax begins to soften or deform. It affects:

  • Whether processing temperatures are adequate

  • Whether the material will deform or degrade under high temperatures

  • Whether it is suitable for high- or low-temperature processing environments

What is Viscosity?

Viscosity represents fluid resistance at a specified temperature, tested via ASTM D3236. It affects:

  • Dispersion effectiveness and compatibility with resins

  • Fluidity requirements during processing

  • Suitability for high-shear or low-shear processing

HDPE

High-density polyethylene wax (HDPE) is polymerized to deliver high stability, low oil absorption, and high hardness, making it suitable for most thermoplastic formulations.
