Brown Pigments for Synthetic Materials
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Specialist in Synthetic Aesthetic Solutions
Deqing Demi Pigment Technology Co., Ltd. is a global partner for the synthetic materials industry. We provide the "Warm Earth" tones required for modern interiors and fashion-grade synthetics. Our pigments are chosen for their refined particle size and absolute lightfastness, ensuring that synthetic products—from faux leather to vinyl flooring—maintain their high-end appearance for years without the risk of fading or color shift.
Synthetic Material Usage Areas
- Synthetic Leather (PU/PVC): Natural-look browns for upholstery and fashion.
- Vinyl Flooring (LVT/SPC): Realistic wood-grain colors for flooring layers.
- TPE/TPV Compounds: Heat-stable browns for automotive soft-touch parts.
- Synthetic Fibers: Solution-dyed browns for outdoor carpets and ropes.
Synthetic Grade Brown Specs
| Metric | Standard Value | Standard |
| Heat Stability | 240∘C−280∘C | DIN 53772 |
| Migration Resistance | Grade 5 | ISO 105-X12 |
| Oil Absorption | 18 - 25 g/100g | ISO 787-5 |
| Specific Gravity | 4.5 - 5.1 g/cm³ | ISO 787-10 |
| pH Value | 6.0 - 8.5 | ISO 787-9 |
Attributes for Synthetic Integration
- Zero Bleeding: Will not migrate between different plastic layers (e.g., in multi-ply vinyl).
- Natural Texture: Fine particles ensure a matte, sophisticated finish rather than a "plastic" look.
- Excellent Dispersion: Wets out quickly in both solvent-based PU and plasticized PVC.
- Weather Permanence: Ideal for "Synthetic Wood" used in outdoor decking.
Q: Can these be used in medical-grade TPE?
A: Yes, we provide high-purity grades that meet USP Class VI and FDA compliance for medical and food-contact synthetics.
Q: Are they compatible with phthalate-free PVC?
A: Absolutely. Our pigments are chemically inert and work perfectly with the latest bio-based and non-phthalate plasticizers.
Bespoke Blending for "Natural" Finishes
We provide custom "Nature-Match" blends to replicate specific wood types (Teak, Walnut, Mahogany) for the global flooring industry.
Migration Testing: Our lab can perform "Sandwich" migration tests against your specific substrate to guarantee zero color transfer in multi-material assemblies.
The Science of Warmth & Chroma
In synthetics, color science is about the balance of a∗ and b∗ coordinates. We use spectrophotometry to ensure that "Warm Browns" maintain a specific red-to-yellow ratio. By controlling the "Particle Shape Index," we can influence how the pigment reflects light, allowing us to mimic the "sub-surface scattering" found in natural leather and wood. This creates a "Depth of Color" that is far more realistic than standard industrial pigments.
