Key Features of High Temperature Ceramic Fiber Board

High-temperature Resistance

The melting point of high-temperature resistant ceramic fiber board insulation can reach up to 1700 degrees Celsius. It has a strong ability to withstand high temperatures, exhibiting thermal stability and resistance to thermal shock. With a linear expansion coefficient ranging from 4% below 1350℃, it maintains a good structure even during rapid temperature changes.

Low Thermal Conductivity

The thermal conductivity coefficient of the fireproof fiber board ranges from 0.09 to 0.22 W/(m·K) between 400-1000ºC. It is lower than dense refractory bricks. This feature effectively reduces heat transfer and achieves thermal insulation. Additionally, with a density between 260-320 kg/m³, it can effectively reduce building weight loads and improve insulation performance.

Strong Processability

The aluminum silicate fiber board is highly processable due to its strong flexibility. It can be altered in size and shape through cutting, shaping, bonding, sewing, and other processing methods to meet the dimensional requirements of different application scenarios. To enhance tensile strength, reinforcing materials such as metal wires can be added to the ceramic fiber board.

Strong Corrosion Resistance

Kerui ceramic fiber insulation board exhibits strong chemical corrosion resistance, with its composition having good chemical stability. Its porous structure and high-temperature stability enable it to withstand corrosion in acidic, alkaline, and neutral chemical environments, maintaining stability in high-temperature chemical reactions.

Environmental Friendly

Environmentally friendly, the high temperature fiber board is a tasteless, non-toxic, eco-friendly material composed of natural ingredients without harmful substances. It does not emit harmful gases at high temperatures during use and can be recycled for reuse after consumption, helping to reduce pollution and waste.

Absorb Sound Waves

The various characteristics of the ceramic fiber insulation board, such as its porous structure, low density, lightweight, and fiber wrapping structure, allow it to absorb, reflect, and reduce the intensity of sound waves, making it widely used in industrial sound insulation applications.

Applications of Kerui Ceramic Fibre Board
