Product description

The Refractory Ceramic Fiber Board use high-quality ceramic fiber as the base material, and through a specific processing technology, it forms a high-density plate structure. And our products are widely used in industrial furnaces, metallurgy, electric power, chemical industry and other fields.

Features

Excellent thermal insulation performance
The core advantage of our products lies in their excellent thermal insulation performance. Its thermal conductivity is as low as 0.05 W/m·K, which is much lower than traditional refractory bricks and other thermal insulation materials.

Excellent high temperature resistance
The Refractory Ceramic Fiber Board has excellent high temperature resistance, and its fire resistance limit can reach 1260℃ to 1600℃, which is suitable for most high-temperature environments.

Excellent compressive strength
Our products not only have excellent thermal insulation but also have high compressive strength, usually reaching more than 1.2 MPa. This property enables it to withstand mechanical pressure and impact in high temperature environments and is suitable for high-temperature furnaces and other high-pressure process environments.

Excellent processing performance
Our products have good processing performance and can be cut and formed according to different application requirements. Whether it is used for thermal insulation of complex structures or as a lining material inside the furnace body, refractory ceramic fiberboard can be customized according to actual needs to meet the needs of different sizes and shapes.

Applications

Industrial furnaces
Refractory Ceramic Fiber Board is used as furnace linings and insulation materials to effectively improve the thermal efficiency of furnaces and reduce energy consumption.

Metallurgical industry
During the smelting process of steel, aluminum alloys, etc., our fiberboards are used for thermal insulation and protection of high-temperature components to ensure long-term stable operation of equipment.

Power industry
Used for thermal isolation of boilers, pipelines and other equipment to reduce heat loss and improve power generation efficiency.

Chemical industry
The high temperature resistance of our products makes them an ideal choice for high-temperature chemical reaction vessels, capable of withstanding complex chemical environments.
