Black Iron Oxide for Industrial Coloring
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
The Reliable Engine of Industrial Black
Deqing Demi Pigment Technology Co., Ltd. is the strategic choice for global industrial coloring needs. We recognize that in large-scale manufacturing, "Supply Reliability" is as important as "Pigment Quality." Our industrial black series is produced in high-capacity facilities with rigorous quality controls. We provide the "Mineral Core" that ensures every batch of your industrial product—from tires to roofing—maintains its professional, dark aesthetic.
Industrial Black Usage Areas
- Rubber Industry: Durable black for tires, conveyor belts, and flooring.
- Asphalt Modification: UV-stable black for roads, paths, and driveways.
- Packaging Materials: Opaque black for heavy-duty industrial containers.
- Textile Backings: Permanent black coloring for carpet backings and felts.
Industrial Black Technical Specs
| Metric | Value | Standard |
| Fe3O4 Content | 88% - 93% | ISO 1248 |
| Oil Absorption | 15 - 25 g/100g | ISO 787-5 |
| PH Level | 5.0 - 8.0 | ISO 787-9 |
| Sieve Residue (325 Mesh) | Max 0.3% | ISO 787-7 |
| Tinting Strength | 100% ± 5% | ISO 787-24 |
Core Advantages
- Extreme Durability: Resists fading under intense sunlight and harsh weather.
- Economical Loading: High tinting power reduces the cost-per-unit.
- Non-Abrasive: Synthetic purity protects mixing and extrusion equipment.
- Universal Stability: Safe for use in both acidic and alkaline environments.
Q: Is this suitable for coloring concrete?
A: Yes, it is fully alkali-resistant and a standard choice for darkening masonry and pavers.
Q: How does it compare to carbon black?
A: Iron oxide is more weather-resistant and doesn't "float" or "rub off" as easily in mineral-based products like cement or rubber.
Industrial Logistics Services
We offer "Bulk Container Liners," providing the pigment in large-format packaging to reduce handling time in high-volume factories.
Custom Grind Profiles: We can adjust the particle size to ensure optimal dispersion in your specific industrial mixer.
The Science of Particle Homogenization
In industrial black, the science lies in "Particle Size Equilibrium." We use "Air-Jet Milling" to ensure that the distribution curve is balanced. If particles are too fine, they dust; if too coarse, they settle. Our scientific calibration ensures a "Mid-Range" distribution that allows the pigment to stay in suspension during liquid processing while providing maximum surface area for color development during solid mixing. This results in the "Homogeneous Depth" required for high-quality industrial goods.
