Synthetic Red Oxide 101

High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.

Precision Synthesis for Global Performance

Deqing Demi Pigment Technology Co., Ltd. is a specialist in the 101 synthetic series. We recognize that for high-spec engineering, purity is everything. Our 101 grade is manufactured in state-of-the-art calcination kilns, ensuring that the crystal structure is perfectly formed. We provide the "High-Purity" red that serves as a critical component in everything from heat-resistant polymers to high-performance industrial primers, backed by our commitment to zero-defect manufacturing.

Grade 101 Usage Areas

  • Engineering Plastics: Stable color for high-processing-temp resins (PA, ABS).
  • Coil Coatings: High-durability red for metal roofing and siding.
  • Brake Linings: Critical friction material component with high thermal stability.
  • Ceramic Glazes: Consistent red coloring for tiles and sanitary ware.

Core Advantages

  • Supreme Heat Stability: Resists color shift at temperatures where other reds fail.
  • Excellent Weathering: 100% lightfast and resistant to environmental acids.
  • High Purity: Low levels of trace metals and salts ensure chemical neutrality.
  • Deep Undertone: Provides a sophisticated blue-shade red for high-end aesthetics.
  • Q: What makes 101 different from 130?

    A: 101 is a calcined grade with higher purity (98%+) and much higher heat stability compared to the precipitated 130 grade.

  • Q: Can it be used in glass manufacturing?

    A: Yes, its high Fe2​O3​ content and low impurity levels make it suitable for glass coloration and polishing.

Technical Customization Services

We offer "Surface De-Gassing," providing an ultra-dry 101 grade to prevent moisture-related defects in plastic molding.

Custom Micronization: We can provide jet-milled 101 with an average particle size (D50) of less than 0.5 microns for high-gloss coatings.

The Science of Calcination Morphologies

The performance of Red 101 is rooted in its "Thermodynamic History." By calcining the iron at temperatures above 700∘C, we force the hematite into a "Spherical-to-Rhombohedral" crystal habit. This scientific shape is the most stable configuration for iron oxide, resulting in a lower surface area than needle-shaped pigments. This reduces oil absorption and significantly increases the "Packing Density" of the pigment in a coating, leading to a harder, more durable, and more heat-resistant film than standard red oxides.
