Product Overview
HENGRUI Chromium-Containing Ceramic Fiber Blanket is a premium refractory insulation material designed for extreme high-temperature applications. With a maximum service temperature of 1500℃ and a continuous working temperature of 1350℃, this blanket offers superior performance compared with standard ceramic fiber blankets.
The product is light green in color, flexible, and formed as an interwoven blanket with uniform fiber diameter, long fiber length, and low shot content. It is supplied in woven bag packaging, 2 rolls per bag, and can be easily rolled, transported, and installed.
Key Features & Properties
- 🔥 Ultra-High Temperature Resistance – Maximum 1500℃, continuous service at 1350℃.
- 🛡️ Low Thermal Conductivity – <0.186 W/m·K at 1000℃, ensuring effective insulation.
- ⚖️ Lightweight – Bulk density ~128kg/m³, reducing structural load.
- 💪 High Stability – Linear shrinkage < -3% at 1350℃, excellent dimensional stability.
- 🔄 Excellent Thermal Shock Resistance – Withstands rapid temperature changes without cracking.
- 🎯 High Tensile Strength & Durability – Strong fiber interweaving prevents delamination and wind erosion.
- 🔇 Multifunctional – Insulation, fireproofing, sound absorption, and noise reduction.
Manufacturing Process
- The chromium ceramic fiber blanket is manufactured through:
- High-temperature melting and fiberization – Fibers are produced by high-speed spinning.
- Double-sided needling process – Enhances fiber interweaving and mechanical strength.
- No additives – Ensures chemical stability and purity.
- Compared with standard ceramic fiber blankets, the chromium-containing type demonstrates improved anti-delamination, wind erosion resistance, flexibility, and tensile strength, resulting in better performance and reduced material loss during use.
Typical Applications
- The 1500℃ chromium ceramic fiber blanket is suitable for a wide range of high-temperature insulation and fireproofing applications:
- Industrial kilns & furnace linings
- High-temperature heating equipment and pipelines
- Boiler insulation and turbine heat shields
- Nuclear and power plant insulation systems
- Chemical industry reactors & thermal processing units
- Fireproof and thermal insulation for high-rise buildings
- Furnace doors, kiln covers, and expansion joints
- High-temperature filtration media
Chromium vs. Zirconium Ceramic Fiber Blanket
| Property | Chromium-Containing Blanket | Zirconium-Containing Blanket |
| Maximum Temperature | 1500℃ | 1430 |
| Continuous Working Temp. | 1350℃ | 1200 |
| Key Composition | Cr₂O₃ (Chromium Oxide) | ZrO₂ (Zirconium Oxide) |
| Performance | Better thermal stability & strength | Standard high-temp performance |
👉 Advantage: Chromium ceramic fiber blanket offers +100℃ higher temperature resistance compared with zirconium type, making it more reliable in demanding applications.
