Firller ceramic fiber blanket is made from a blend of alumina, and silicate by a unique spinning technology.
It is widely used in power generation, iron, steel, aluminum, non-ferrous metals, glass, ceramics, aerospace, super alloys, petrochemical, semiconductors, cement, automotive, etc.
The temperature level is 1100-1430℃ (2012℉–2600℉).
1. Excellent heat stability and thermal shock resistance
2. Low thermal conductivity and low shrinkage
3. Good tensile strength and thermal insulation
4. Noise reduction
5. Fireproof
1. Linings and backup insulation for all types of furnaces, heaters, and kilns
2. External insulation, such as boiler, turbine, duct and piping, precision casting shell
3. Vehicle and domestic appliance insulation
4. High-temperature sealing material, such as ladle lid, duct connecting part
5. Noncombustible materials for building
6. High-temperature gas filtration material, high-temperature part sound absorbing material
7. Pressure and cryogenic vessel fire protection
8. Furnace repairs
