Ceramic Fiber Board

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

Characteristics
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

Applications
Hot face lining of ceramic kilns
Insulation for kiln car
Furnace door insulation
Ducts insulation
General thermal barriers
High temperature insulation
