Ceramic Fiber Inorganic Board

1. Product Description

This product features excellent thermal resistance, insulation performance, and high mechanical strength. It has a smooth surface and dense structure. It is widely used as internal insulation, fire protection, and high-temperature support structures in various types of high-temperature equipment.

Ceramic fiber inorganic board addresses common issues of traditional fiber boards, such as dust generation, low strength, and poor resistance to wind erosion. It is an ideal material for backing insulation systems in industrial furnaces and can also serve as a refractory component in complex thermal applications.

Depending on application requirements, several product series are available: standard, reinforced, corrosion-resistant, and others.

2. Product Structure & Manufacturing Process

Ceramic fiber inorganic board is made from high-purity ceramic fibers and high-temperature inorganic binders in a specified ratio, using fully automated vacuum forming, drying, and cutting processes. The internal structure features uniform fiber distribution and high strength, providing not only excellent insulation properties but also a certain load-bearing capacity and resistance to mechanical impact.

✅ Fiber Base Material: High-temperature ceramic fiber based on aluminum oxide and silicon oxide

✅ Binder System: High-temperature inorganic binder system (e.g., silicates, aluminates)

✅ Forming Method: Vacuum forming followed by drying and surface densification

3. Key Features

（1）Excellent High-Temperature Resistance
Continuous service temperature reaches 1260 °C, and certain high-purity types can exceed 1350 °C, making the material suitable for extreme high-temperature applications.

（2）Low Thermal Conductivity & High Insulation
The porous internal structure creates a “layer of stationary air,” effectively blocking heat transfer and significantly reducing heat loss.

（3）High Strength & Wind Erosion Resistance
The material has rigidity and high compressive, flexural, and impact strength, far surpassing flexible fiber materials, allowing use in areas with strong mechanical impact, such as burner window zones.

（4）Dimensional Stability & Low Deformation
Excellent dimensional stability under repeated thermal cycles, outstanding resistance to thermal shock, and minimal cracking or delamination.

（5）Non-Toxic & Environmentally Safe
Completely inorganic composition, asbestos-free, no harmful gases, no dust contamination during production or use, compliant with environmental regulations.

（6）Easy Installation & Machining
The material can be easily cut, milled, drilled, and otherwise mechanically processed, facilitating installation and structural fabrication.

9. FAQ

Q1: Does the ceramic fiber inorganic board generate dust or crack?
A1: The product is manufactured using vacuum forming, resulting in a dense internal structure. It does not generate dust or crack during operation. For enhanced wind erosion resistance, a coated version can be selected.

Q2: Can on-site mechanical processing be performed?
A2: Yes, cutting, drilling, milling, and fabrication of complex-shaped components according to drawings are supported for quick installation.

Q3: What is the difference from ceramic fiber blanket?
A3: The inorganic board is a rigid structure with high load-bearing capacity and impact resistance, suitable for applications requiring dimensional stability and high strength. Ceramic fiber blanket is a flexible material used for wrapping or joint insulation applications.

Ceramic fiber inorganic board, with its outstanding high-temperature resistance, thermal insulation, and mechanical strength, has become an indispensable key material in energy-efficient insulation systems for high-temperature processes. Whether used in the steel, metallurgical, glass, power, or chemical industries, as well as emerging fields such as renewable energy and environmental applications, it plays a vital role.
