Pigments Powder for Masterbatch
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Strategic Partner for Masterbatch Producers
Deqing Demi Pigment Technology Co., Ltd. is a primary supplier to the global masterbatch industry. We provide the "building block" inorganic pigments that enable the production of high-quality color concentrates. Our manufacturing process ensures that our powders are free of impurities that could cause "specks" in thin films or fibers. We understand that the profitability of a masterbatch producer depends on pigment consistency and throughput, and we deliver materials that optimize both.
Masterbatch Production Fields
- Color Masterbatch: Base pigments for universal and resin-specific concentrates.
- Functional Masterbatch: Combined color and additive (UV/Antistat) systems.
- Mono-color Concentrates: High-purity single pigment batches for professional compounding.
- Fiber Masterbatch: Ultra-fine pigments for spin-dyeing of synthetic textiles.
Masterbatch Pigment Specifications
| Metric | Standard Value | Unit |
| Oil Absorption | 12 - 18 | g/100g |
| Filter Pressure Value | < 1.0 | bar/g (at 14$\mu\text{m}$) |
| Specific Surface Area | 8 - 12 | m2/g |
| Hegman Fineness | 7.5+ | Hegman Units |
| Heat Stability | Up to 300 | Degrees Celsius |
Attributes for High-Speed Compounding
- Low Viscosity Impact: Optimized surface chemistry allows for higher pigment-to-resin ratios.
- Rapid Wetting: Reduces "residence time" in the extruder, preventing resin degradation.
- Consistency: Tight control over tinting strength ensures the "let-down" ratio remains constant.
- Dust Control: Densified powder options available to minimize environmental dust in the plant.
Q: How does the pigment affect the masterbatch shelf life?
A: Our inorganic pigments are completely stable and do not react with the carrier resin, ensuring a shelf life of several years if stored correctly.
Q: Can these be used in biodegradable masterbatches?
A: Yes, our inorganic powders are compatible with PLA and PBAT carriers, provided the carrier processing temperatures are within the pigment's stability range.
High-Efficiency Dispersion Services
We provide "easy-disperse" grades that have been pre-treated with specific waxes or wetting agents tailored to the client's target carrier resin (PE, PP, PS, etc.).
Batch Reporting: Every shipment for masterbatch production includes a detailed particle size distribution report, ensuring that the FPV (Filter Pressure Value) remains within the strict limits required for high-speed fiber or film production.
Quantifying Dispersion Quality
In masterbatch science, the "Dispersion Index" is the critical metric. We use microscopic analysis to ensure that 99.9% of pigment particles are below the 1-micron threshold. By achieving a perfect Gaussian distribution of particle sizes, we maximize the "light-scattering efficiency," which translates to higher opacity and better color value for the end user. We provide spectral reflectance data for the "Pure Pigment" versus "Let-down State," helping masterbatch formulators calculate the exact pigment concentration needed to achieve a target Delta E.
