Firller ceramic fiber board is made of refractory fiber by the process of vacuum forming or dry process refining.
it is a practical and efficient material for kilns and furnaces, pipes, and other thermal insulation equipment.
1. Excellent heat stability and thermal shock resistance.
2. Low thermal conductivity and low shrinkage.
3. High compression strength
4. Flexible and convenient to install
5. Non-fragile and non-combustible
1. The wall liner and back lining materials of high-temperature reaction, reheating equipment, and various industrial furnaces such as used glass tempering furnaces, pottery kilns, ceramic kilns, and tunnel
2. The insulating and fireproof plate of the furnace door and roof or house chimney and fireplace
3. Lows fireproof and insulation for chimney cake ovens, pizza, boilers, and heater combustion chamber
4. Aluminum factories-reduction cell firebricks back linings
5. Ladle furnace backing
6. Shipping, aviation, precision industrial equipment
7. Refractory and thermal insulation material in the kiln or furnace of the construction industry for heating and wall liner of high-heat
