Why Color Masterbatch Quality Depends on the Right Wax Additive

In the masterbatch industry, vibrant color and processing stability are non-negotiable. Yet challenges like pigment re-agglomeration, poor flowability, and wax blooming frequently compromise product quality—especially in high-loading systems.

That’s where specialty wax additives come in. These micronized or functionalized waxes significantly improve pigment wetting, flow characteristics, and surface aesthetics in thermoplastic color masterbatches.

Key Benefits of Wax in Masterbatch Formulations

🔹 Superior Pigment Dispersion
Wax acts as a dispersing assistant, coating pigment particles and preventing re-agglomeration during extrusion.

🔹 Slip Modifier
Reduces friction, improves surface feel and processability.

🔹 Anti-Blooming Control
Stabilizes formulation and prevents wax/filler migration to the surface.

Typical Polymer Systems

• PE, PP, PS, EVA
• PA6, ABS, PC, TPU
