Ceramic Fiber Board
SDTECH Ceramic Fiber Board is a high-performance refractory insulation material manufactured through a wet forming process using both organic and inorganic binders.
With an operating temperature range of 950°C (1,700°F) to 1,450°C (2,600°F), it is well suited for applications requiring high insulating performance and structural stability, such as melting and electric furnaces, doors, and ducts. Its excellent insulating properties and low thermal mass maximize energy efficiency, while its light weight and ease of fabrication make for straightforward installation.
