Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Masterbatch Iron Oxide Powders
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Foundation of High-Quality Concentrates
Deqing Demi Pigment Technology Co., Ltd. is the core supplier for world-class masterbatch producers. We recognize that a masterbatch is only as good as the powder inside it. Our series is developed to maximize the efficiency of twin-screw extruders. We provide the high-tinting strength and exceptional dispersion characteristics that allow masterbatch manufacturers to reduce their usage rates while maintaining superior color depth and opacity for their global clients.
Masterbatch Usage Areas
- Color Concentrates: Base pigments for universal and resin-specific masterbatches.
- Additive Masterbatch: Combined color and UV-stabilizer packages.
- Fiber Grade: Fine-milled oxides for spin-dyed synthetic fibers and textiles.
- Packaging: Opaque colorants for cosmetic and pharmaceutical containers.
Masterbatch Grade Technical Specs
| Metric | Value | Standard |
| Residue on 325 Mesh | Max 0.01% | ISO 787-7 |
| Particle Size (D100) | < 10 μm | Laser Diffraction |
| Tinting Strength | 100% ± 2% | ISO 787-24 |
| Total Iron Content | Min 95% | Chemical Analysis |
| Specific Surface Area | 8 - 12 m²/g | BET Method |
Performance Characteristics
- Maximum Loading: Low oil absorption allows for higher pigment concentrations.
- Zero Agglomeration: Advanced milling ensures easy breakup during melt-mixing.
- Consistency: Tight color tolerances mean no adjustment is needed for every batch.
- Carrier Compatibility: Works across PE, PP, EVA, and biodegradable resins.
Q: Can your powders be used for Fiber Grade masterbatch?
A: Yes, we provide specialized grades with ultra-low residue to prevent filament breakage during spinning.
Q: Do you offer pre-mixed colors for masterbatch?
A: We can provide customized "Dry Blends" of Red, Yellow, and Black to meet your specific target shade exactly.
Extrusion Efficiency Consulting
We offer "Torque Analysis" data to show how our pigments behave in your extruder, helping you optimize throughput and energy consumption.
Custom De-dusting: For cleaner factory environments, we can provide our powders in a "low-dust" micro-granule form that is still easy to disperse.
The Science of Dispersive Mixing
In masterbatch production, we focus on the "Break-down energy." Our pigments are engineered with specific surface treatments that lower the cohesive forces between particles. During the high-shear environment of a twin-screw extruder, these "clusters" shatter into primary particles instantly. This ensures that the let-down in the final application is seamless, providing a "mirror-finish" color without any visible specks or surface imperfections.
