Ceramic Fiber Board

Product Description

Alumina ceramic fiber board for kiln and furnace

Refractory ceramic fibre board is a vacuum formed product that resists higher gas velocities than ceramic fibre blanket. Ceramic fiber board is ideal for furnace, boiler duct and stack lining due to its low thermal conductivity and low heat storage allowing shorter cycle times and quicker access for maintenance.

 

Features

1. Low thermal conductivity and low heat storage

2. High temperature stability and resistant to thermal shock

3. High crushing strength and good toughness

4. Allow machining and cutting, easy application

5. Resistant to airflow erosion

 

Typical Application

1. Hot face lining of ceramic fiber kiln   

2. Insulation for kiln car

3. Furnace door insulation

4. Duct insulation

5. General thermal barrier

6. High temperature insulation
