How do dispersing aids actually help color?

They wet and wrap pigments so they don’t clump back together. You get a tighter particle size distribution, higher dispersion efficiency, and long-term stability.

If color strength is equal, you can often dose less pigment. You’ll also use fewer additives and scrap less—so yes, total cost goes down.

What’s the upside for final product quality?

Brighter color, higher gloss, tighter color tolerance, and less blooming/migration over time.

How do you reduce color blooming and migration?

Use alpha-olefin synthetic, highly branched dispersants. They’re more compatible with the resin and “lock” pigments in place, so the color stays put and buildup drops.

How do you keep batches consistent, color wise?

Tight control on raw materials and process, plus outgoing checks on dispersion, viscosity, content, etc. That’s how you keep recipes repeatable and color differences in spec.

Agent for high-performance dispersing masterbatch

The pigment powder usually exists in the form of small particles at the microscopic level, and has a high tendency to agglomerate. During the masterbatch production process, pigment agglomeration may lead to uneven color distribution and insufficient color intensity. Rallychem provides high-performance dispersion additives that can effectively improve the dispersion of pigments, reduce the use of expensive pigments, and increase the brightness of the product.

Dominance

Good dispersion performance

Rallychem's polymer has high viscosity, high dispersion efficiency and can reduce the amount of dispersant added.

Resistance to precipitation, bright color

Alpha olefin synthesis with more branch chains, is less prone to precipitation and helps maintain color vibrancy over time.

Batch stability, reduced color difference

Rallychem understands the importance of batch stability for masterbatch production, and we have a strict quality inspection system to our products to help customers with peace of mind.

How Do Rallychem Wax Additives Optimize Masterbatch Dispersion and Polyethylene Wax Dispersion?

Masterbatch dispersion optimization relies on low-melt-viscosity polyethylene wax dispersion grades and polar oxidized PE waxes that wet pigment agglomerates, prevent re-flocculation, and lower extruder filter pressure values (FPV) by 35% to 45% (Rallychem 2026). First, data shows our research at the USD 20 million Rallychem Application Lab measured 20% higher carbon black and organic pigment tinting strength and 16% lower twin-screw compounding torque across 10,000 customers worldwide. Second, tailored masterbatch dispersion packages include: 1. Narrow-MWD homopolymer polyethylene wax dispersion grade RL-110 (viscosity 80–150 cps at 140 C) for 40% to 50% high-jetness carbon black masterbatch; 2. High-molecular-weight PE wax RL-115 for 75% to 85% CaCO3 and talc filler masterbatch; 3. Polar oxidized PE wax RL-53 and targeted polyester wax RL-691A for engineering plastic (PA6, PET, PBT) color masterbatch. For example, in practice using Rallychem RL-110 cuts screen-pack change frequency in half.
