Flush Pigments: The Game Changer in Plastic Masterbatch Manufacturing

Flush pigments are prepared by transferring pigment press cake directly into a carrier (often polyethylene wax), without converting the pigment into dry powder.

Key Advantages of Flush Pigments in Masterbatch Manufacturing:

Superior Dispersion: Flush pigments deliver pigments in a fully dispersed, agglomerate-free form. The result is exceptional color consistency and strength, even when using low-shear mixers or in applications where uniform color is critical (such as films and fibers)
High Color Strength: Because particle aggregation is avoided, the full coloring potential of the pigment is available, providing richer colors at lower pigment dosages—which enhances product quality and reduces raw material costs.
Improved Productivity: Flush pigment concentrates are easier to handle than powders, reducing dust and improving workplace cleanliness. Production cycles are faster, with shorter color changeover times and higher output per hour.
Cleaner Production Environment: Flush forms create less dust than dry pigment powders, ensuring a safer and cleaner processing environment.
Compatibility: The polyethylene wax carrier is compatible with common plastics such as polyolefins and PVC, supporting broad application flexibility in masterbatch production
Energy Efficiency: Since pigments are pre-dispersed, less energy is required during compounding, resulting in lower power consumption.

How Flush Pigments Work
Unlike traditional pigment processing—which requires breaking down hard agglomerates—flush pigments embed disaggregated primary pigment particles within a polymer-compatible wax. This flush is then directly incorporated into the plastic masterbatch, ensuring even dispersion and eliminating common defects like streaks, color inconsistency, or undispersed spots. 

Application & Performance
Flush pigments excel in applications demanding high color intensity and uniformity, such as thin films, colored fibers, and injection molded parts. 
Flush pigments are a pivotal innovation for plastic masterbatch makers, delivering brighter colors, better dispersion, faster production and cleaner workplaces—helping manufacturers meet modern demands for quality, cost-efficiency, and environmental responsibility.
