Pre-Dispersed Pigments

Pre-dispersed pigments are high-concentration, single-color pigment preparations that deliver precise, dust-free and highly consistent coloring. Unlike complete masterbatch that already contains the final color recipe, pre-dispersed pigments isolate a single pigment in a carrier system, giving formulators and compounders maximum flexibility to mix precise shades. For manufacturers requiring strict color control, faster changeovers and cleaner handling, they are the professional-grade building block for plastic coloring.

What Are Pre-Dispersed Pigments?

Pre-dispersed pigments (also called pigment concentrates or mono-pigment dispersions) suspend one organic or inorganic pigment at high concentration — typically 50-70% — in a polymer-compatible carrier with wetting/dispersing aids. The pigment is fully wetted and de-agglomerated during production, so it disperses instantly and uniformly when let down into the base resin. This eliminates the dust, uneven dispersion and tinting-strength variation of raw pigment powder while giving formulators the freedom to blend pigments into any final color.

Key Benefits of Pre-Dispersed Pigments

• Dust-free handling for a cleaner, safer production environment
• High tinting strength (70% pigment, 90% TiO2) for efficient, lower-cost dosing
• Excellent dispersion with no specks, streaks or agglomeration
• Complete formulation freedom to blend any final color in-house
• Precise, repeatable dosing for batch-to-batch consistency
• Faster color changes and less finished masterbatch inventory
• Organic and inorganic options covering the full color spectrum
• Compatible with PE, PP, PS, ABS and engineering resins

Technical Highlights

MHK Color supplies pre-dispersed pigments at 70%-90% pigment content in universal polyolefin or polymer-specific carriers. Our dispersions develop full color at low addition rates, with verified heat resistance up to 300°C, light fastness of grade 6–8, and migration resistance for regulated applications.

How to Choose the Right Pre-Dispersed Pigments

Choosing the right pre-dispersed pigment depends on your color target, polymer system and end-use requirements.

• For vivid saturated shades, choose organic pigments (red, yellow, blue, green)
• For food contact or medical use, specify FDA or USP-compliant grades
• For engineering plastics, match the carrier to PA, PC, PET or PBT
• For outdoor products, verify light fastness and UV stability of the chosen pigment

Typical Applications

Pre-dispersed pigments suit color compounders, masterbatch producers and processors that color in-house in film, injection molding, blow molding and fiber extrusion. They are especially valuable for custom color development, small-batch production and applications requiring strict Delta E control.
