Iron Oxide Orange is an inorganic synthetic pigment based on hydrated iron oxide (FeOOH), produced through controlled precipitation and calcination processes. It delivers stable orange hues ranging from bright yellow-orange to deep red-orange, with consistent color performance across a wide range of applications.
As an Orange Iron Oxide Pigment, it offers strong lightfastness, alkali resistance, and thermal stability—properties that distinguish it from organic orange pigments in demanding industrial and construction environments. The product meets international pigment standards (CI Pigment Orange 78) and complies with REACH regulations, free from restricted heavy metals including lead, cadmium, and hexavalent chromium.
We use high-quality packaging materials and professional packaging, palletizing, and film wrapping equipment.

> View MoreIn architectural finishes, the opacity (hiding power) of orange iron oxide pigment is primarily determined by its ability to scatter visible light. This phenomenon is highly dependent on the particle size distribution (PSD). When the particle size of the iron oxide orange—which is typically a precise composite of hematite (red) and goethite (yellow)—approaches approximately half the wavelength of visible light (roughly 0.2 to 0.4 microns), scattering efficiency reaches its peak. Deqing Demi Pigment Technology Co., Ltd. utilizes advanced precipitation and blending technologies to narrow the PSD of our orange series. By ensuring a high concentration of particles within this optimal range, our pigments provide maximum coverage, allowing paint manufacturers to achieve full opacity with thinner coating films.

| Average Particle Size (μm) | 0.4 - 0.8 | 0.2 - 0.3 |
| Particle Size Distribution | Broad (Irregular) | Narrow (High Uniformity) |
| Contrast Ratio (Opacity) | 92% - 95% | 98% or greater |

Deqing Demi Pigment Technology Co., Ltd. focuses on the research, development, and production of inorganic iron oxide pigments. Our comprehensive portfolio includes iron oxide red, yellow, black, brown, green, orange, and blue. We produce high-performance and high-stability composite pigments across three series: standard, micronized, and low heavy metal content levels. Beyond operational excellence, Demei faithfully fulfills its social responsibilities by protecting the ecological environment and strengthening safe production. We prioritize the health of employees, ensuring that every batch of our orange pigment meets the highest safety and performance standards for the global architectural market.
Since orange is a composite pigment, Deqing Demi Pigment Technology Co., Ltd. uses high-precision computerized color-matching and blending systems to integrate iron oxide red and yellow. By strictly controlling the particle size distribution of each component, we ensure that the final orange pigment maintains high stability and batch-to-batch color accuracy, which is vital for large-scale architectural projects.
Yes. Deqing Demi Pigment Technology Co., Ltd. offers a specialized series with low heavy metal content levels. Our company contributes to sustainable production by protecting the ecological environment and ensuring all products comply with international environmental safety standards, making them the preferred choice for green building certifications.
The micronized series from Deqing Demi Pigment Technology Co., Ltd. features an ultra-fine particle size distribution that significantly improves dispersion efficiency. This results in higher tinting strength, better gloss, and reduced energy consumption during the paint manufacturing process, providing a high-performance solution for premium architectural finishes.
In high-temperature plastic masterbatch manufacturing, the thermal stability of orange iron oxide pigment is primarily determined by its chemical structure. Orange iron oxide is typically a high-stability composite formed by the mechanical or chemical blending of iron oxide red (hematite, alpha-Fe2O3) and iron oxide yellow (goethite, alpha-FeOOH). The critical factor is the dehydration temperature of the yellow component; standard goethite begins to lose its chemically bound water at approximately 180°C to 200°C, shifting towards a redder hue. Deqing Demi Pigment Technology Co., Ltd. utilizes advanced R&D to optimize the blending ratio and surface treatment of these components, extending the stable temperature range to meet the rigorous demands of plastic extrusion and injection molding processes.
| Technical Metric | Standard Orange Iron Oxide | Heat-Stabilized Orange Iron Oxide (Demei) |
| Dehydration Temperature | Approx. 180°C - 200°C | Up to 240°C - 260°C |
| Fe2O3 Content (%) | 88% - 90% | 90% or greater |
| Color Change (Delta E) | High (Visible darkening) | Low (Color retention at 220°C) |
| Oil Absorption (g/100g) | 25 - 35 | 20 - 28 |
| Volatile Matter (105°C) | 1.0% or less | 0.5% or less |
