Product Details
Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Paper Grade Iron Oxide Pigments
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Sustainable Color for the Paper Industry
Deqing Demi Pigment Technology Co., Ltd. provides the global paper industry with eco-friendly mineral colorants. We understand that paper manufacturing requires pigments that are both high-performing and environmentally responsible. Our paper-grade series is designed for maximum retention within the fiber matrix. We provide the "Natural Palette" that allows paper mills to produce beautiful, light-stable products that are safe for recycling and meet the strictest environmental standards.
Paper Grade Usage Areas
- Decorative Laminates: Base colors for wood-grain and stone-pattern furniture foils.
- Construction Paper: Fade-resistant coloring for school and craft supplies.
- Luxury Packaging: Deep, earthy tones for premium bags and boxes.
- Mulch & Seed Mats: Biodegradable coloring for agricultural paper products.
Paper Grade Technical Specs
| Metric | Value | Standard |
| Water Solubles | Max 0.1% | ISO 787-3 |
| Residue on 325 Mesh | Max 0.05% | ISO 787-7 |
| PH Value | 6.5 - 7.5 | ISO 787-9 |
| Lightfastness | 8 (Blue Wool) | ISO 105-B02 |
| Specific Resistance | Min 3000 Ω⋅cm | ISO 787-14 |
Core Advantages
- High Retention: Optimized surface charge for maximum adherence to paper fibers.
- Bleed Resistance: 100% insoluble in water, preventing color transfer when wet.
- Chemical Neutrality: Does not affect the sizing or wet-strength additives in the pulp.
- Recyclability: Inorganic mineral nature is compatible with standard recycling streams.
Q: Will these pigments cause "Two-Sidedness" in the paper?
A: Our pigments are micronized to ensure even distribution, minimizing the color difference between the wire and felt sides of the sheet.
Q: Are they safe for food-contact paper?
A: Yes, we offer high-purity grades that comply with FDA and BfR regulations for food packaging.
Pulp Integration Support
We provide "Retention Aid Compatibility" reports, helping you choose the right polymers to keep the pigment in the sheet and out of your wastewater.
Liquid Dispersion Services: For large mills, we offer pre-dispersed pigment slurries to eliminate dust and simplify automated dosing.
The Science of Fiber Bonding
In paper science, we focus on "Electrokinetic Potential." Since cellulose fibers are negatively charged, we treat our pigments to ensure a balanced surface charge that facilitates "Bridge Bonding." This ensures that the pigment particles are physically trapped within the fiber network. We optimize the particle size to ensure it is large enough to be retained by the wire mesh but fine enough to provide high opacity and a smooth surface finish.
