Ceramic Fiber Board

 Category Ceramic Fiber

General Information
Ceramic Fiber Boards are manufactured in a wet vacuum forming process by blending the chopped ceramic fiber with inorganic or organic binders for excellent abrasive resistance at high temperature. Ceramic fiber boards feature low thermal conductivity, high thermal stability and excellent thermal shock resistance. The products are classified as STD, HP, HA and HZ respectively corresponding to different maximum service temperature 1000°C, 1100°C, 1200°C, and 1350°C.

Advantages
Low heat storage, Low thermal conductivity, Excellenl abrasive resistance,Excellent thermal shock, resistance, Excellent chemical stability, Even density and thickness, Non standard sizes are available upon request.

Applications
Hot air duct lining, Shuttle kiln with high gas velocity, Laboratory furnace, Kiln car insulation, Die-cut high temperature seal
