Comprehensive information about our iron oxide pigments including specifications, applications, advantages, and more
Rubber Grade Iron Oxide Pigments
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Coloring the World's Toughest Materials
Deqing Demi Pigment Technology Co., Ltd. is a trusted supplier to the global rubber and tire industries. We recognize that rubber compounding is an exact science. Our rubber-grade series is produced with a focus on "Purity Above All." We ensure that our pigments do not interfere with the cross-linking of the rubber chains, providing a color solution that is as durable as the material itself. From heavy-duty tires to intricate industrial gaskets, our colors are built to last.
Rubber Grade Usage Areas
- Automotive Tires: Branding and identification colors for tire sidewalls.
- Industrial Belting: Durable coloring for conveyor belts and transmission drives.
- Rubber Flooring: UV-stable pigments for playground and gym surfaces.
- Footwear Soles: Abrasion-resistant colors for high-performance athletic shoes.
Rubber Grade Technical Specs
| Metric | Value | Standard |
| Manganese (Mn) Content | Max 0.01% | Chemical Analysis |
| Copper (Cu) Content | Max 0.005% | Chemical Analysis |
| Heat Stability | Up to 280∘C (Yellow) / 800∘C (Red) | Internal Method |
| Moisture Content | Max 0.5% | ISO 787-2 |
| Oil Absorption | 15 - 25 g/100g | ISO 787-5 |
Performance Characteristics
- Zero Degradation: Prevents the "softening" or "brittleness" associated with metal impurities.
- High Heat Resistance: Withstands the 150∘C−200∘C vulcanization cycles.
- Intense Dispersion: Mixes evenly into high-viscosity rubber compounds without clumping.
- Flexibility: Color remains uniform even when the rubber is under high elongation.
Q: What is "Rubber Poisoning" in pigments?
A: Certain metals like copper and manganese catalyze the oxidation of rubber. Our pigments are certified "Low-Mn/Cu" to prevent this.
Q: Can these be used in Silicone rubber?
A: Yes, our high-purity reds and blacks are excellent for high-temperature silicone applications.
Compounding Technical Support
We offer "Rheology Testing," providing data on how our pigments affect the Mooney Viscosity of your rubber compounds.
Custom Masterbatching: We can provide pre-dispersed pigment pastes in various carrier oils to simplify your rubber mixing process and reduce dust.
The Science of Polymer Interaction
In rubber science, we focus on "Cross-link Interference." Because pigments are physical particles, they can get in the way of the sulfur bridges that hold rubber together. We optimize the "Particle Geometry" of our rubber-grade oxides to ensure they sit harmoniously within the polymer matrix. By controlling the "Surface Moisture," we prevent the formation of steam pockets during vulcanization, ensuring a solid, void-free finished product with uniform color and strength.
