> Ver másIron Oxide Yellow 313 is chemically characterized as Goethite (FeOOH). In plastic extrusion processes, the primary challenge is the dehydration of the pigment, where the chemically bound water in the hydroxide structure is released, causing a color shift toward red. The 313 grade is specifically engineered with a robust crystalline lattice that raises the threshold for this dehydration reaction. Deqing Demi Pigment Technology Co., Ltd. utilizes advanced calcination and surface treatment technologies to stabilize the needle-like particle morphology of our iron oxide yellow. This structural integrity allows the pigment to maintain its vibrant yellow hue even when subjected to the high temperatures and shear forces typical of thermoplastic processing.
| Technical Property | Standard Iron Oxide Yellow | Iron Oxide Yellow 313 (Heat Stable) |
| Chemical Structure | FeOOH (Standard) | FeOOH (Stabilized Lattice) |
| Heat Resistance Threshold | Approximately 180°C - 200°C | Up to 240°C - 260°C |
| Particle Shape | Acicular | Reinforced Acicular |
| Oil Absorption (g/100g) | 30 - 45 | 25 - 35 |
| Color Change (Delta E) | Significant shift above 200°C | Stable under 240°C |
As a leading developer of inorganic pigments, Deqing Demi Pigment Technology Co., Ltd. offers Iron Oxide Yellow 313 in three specialized series: standard, micronized, and low heavy metal content. Our micronized series is particularly effective for plastics, ensuring rapid dispersion and a smooth surface finish. Beyond technical excellence, Demei faithfully fulfills its social responsibilities by maintaining eco-friendly production cycles and strictly monitoring safe production environments to protect both the health of employees and the local ecosystem.
The 313 grade is preferred due to its enhanced thermal ceiling. Deqing Demi Pigment Technology Co., Ltd. produces high-performance composite iron oxide pigments that do not degrade during the double-heat cycle of masterbatch creation and subsequent final product extrusion. This stability ensures color consistency across large-scale manufacturing runs.
Deqing Demi Pigment Technology Co., Ltd. prioritizes protecting the ecological environment through closed-loop water systems and emission controls. Our low heavy metal content series is specifically designed for international markets with strict safety regulations, ensuring that our iron oxide yellow products are as sustainable as they are high-performing.
Yes. The micronized series from Deqing Demi Pigment Technology Co., Ltd. undergoes a high-energy milling process that reduces particle clusters. This allows for faster wetting and dispersion in the polymer melt, which reduces energy consumption and mechanical wear on extrusion equipment, supporting mutual success for our global furniture and industrial partners.
Iron oxide yellow pigments are chemically defined as ferric oxide hydroxide (FeOOH). The primary technical difference between standard grades and the 313 grade lies in the crystal growth control during the precipitation process. Standard iron oxide yellow typically features a broader particle size distribution, whereas the 313 grade is engineered for high tinting strength through a more uniform, needle-like (acicular) crystal structure. Deqing Demi Pigment Technology Co., Ltd. utilizes specialized research and development to optimize these particle shapes, ensuring that our 313 series provides more vibrant yellow undertones and superior opacity in architectural coatings. This refined morphology allows for better light scattering, resulting in a significantly higher color yield compared to conventional yellow pigments.
| Technical Property | Standard Iron Oxide Yellow | Iron Oxide Yellow 313 |
| Chemical Formula | FeOOH | FeOOH |
| Fe2O3 Content (%) | 86% or greater | 86% - 88% |
| Tinting Strength (%) | 95% - 105% (Standard) | 115% - 125% (High-Tinting) |
| Particle Shape | Irregular Acicular | Uniform Needle-like |
| Sieve Residue (45μm) | 0.5% or less | 0.3% or less |
