Ceramic Fiber Board

Ceramic fiber board with high compressive strength, flat surface, and low thermal conductivity, designed for furnace lin.....


Ceramic Fiber Board is manufactured from high-quality, non-brittle ceramic fiber materials, giving it excellent toughness, high compressive strength, and stable structural performance. The board features a smooth, flat surface with uniform density and thickness, making it easy to cut, drill, and machine for precise installation. Designed for high-temperature environments, ceramic fiber boards are available for service temperatures of 1050°C, 1260°C, and 1430°C, making them ideal for wall lining and backup insulation in various heating systems and industrial furnaces.

With low thermal conductivity and minimal thermal shrinkage, ceramic fiber boards provide efficient heat insulation while maintaining dimensional stability under continuous high-temperature operation.
