Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Plastic Grade Iron Oxide Pigments
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Precision Color for the Plastics Industry
Deqing Demi Pigment Technology Co., Ltd. provides the global plastics market with high-performance mineral colorants. We understand that in plastics manufacturing, color consistency is a non-negotiable requirement. Our plastic-grade series is designed to withstand the rigors of injection molding and extrusion. We ensure that our pigments are free from moisture and abrasive impurities, allowing for smooth production runs and vibrant, long-lasting finished products that meet international food-contact and safety standards.
Plastic Grade Usage Areas
- Injection Molding: Consistent color for household goods and toys.
- Blown Film: Thin-gauge coloring for agricultural and packaging films.
- Plastic Pipe: UV-stable coloring for HDPE and PVC water pipes.
- Outdoor Furniture: Weather-resistant pigments for wood-plastic composites (WPC).
Plastic Grade Technical Specs
| Metric | Value | Standard |
| Heat Stability | 200∘C−260∘C | DIN 53772 |
| Filter Pressure Value | < 1.5 bar/g | EN 13900-5 |
| Moisture Content | Max 0.3% | ISO 787-2 |
| Oil Absorption | 15 - 25 g/100g | ISO 787-5 |
| PH Value | 6.0 - 8.0 | ISO 787-9 |
Core Advantages
- Non-Warping: Does not induce crystalline nucleating effects in polymers.
- High Dispersibility: Ensures no "color specks" or streaks in thin-walled parts.
- Chemical Resistance: Unaffected by common plasticizers and processing aids.
- Food Contact Safe: Available in grades compliant with FDA and AP89(1) regulations.
Q: Why do iron oxide yellows change color in plastic?
A: Standard Yellow Oxide loses chemically bound water at high heat. Our plastic-grade yellows are specifically stabilized to prevent this shift.
Q: Will it affect the strength of my plastic part?
A: No, our high-purity pigments are chemically inert and do not degrade the polymer chains.
Thermoplastic Solution Support
We provide "Filter Pressure Value (FPV) Testing" to guarantee that our pigments will not clog your extruder screens during high-speed production.
Custom Hydrophobic Coating: For moisture-sensitive resins like PET or PA, we can provide surface-treated pigments that repel water and improve compatibility.
The Science of Thermal Protection
In plastic coloring, we focus on "Lattice Stabilization." By modifying the crystal surface of iron oxide yellow (FeOOH), we create a thermal barrier that delays the conversion to red (Fe2O3). This allows the pigment to maintain its bright yellow hue even at 240∘C for up to 5 minutes, providing a wider processing window for manufacturers using high-temperature engineering plastics.
