BAOWOOL Ceramic Fiber Board
BAOWOOL Ceramic Fiber Board is made from refractory fibers and binders which have a low organic content, the mixture is vacuum processed into boards that keep good mechanical strength after heating.

Characteristic:
- Low thermal conductivity
- Resistance to thermal shock
- Greater mechanical strength
- Even density, thickness
- Can withstand gas flow velocity of 30 m/sec
- Easy to cut or install
- Good erosion resistance
- Shorter heat up and cool down time
- Asbestos free

Application:
- Hot face lining of ceramic kilns
- Insulation for kiln car and furnace door
- Ducts insulation
- General thermal barriers
- High temperature insulation
