Ceramic Fiber Blanket
General Information
Ceramic fiber blanket is made from high quality Gao-Ling clay, high purity alumina and silica oxides by spun or blown process. It is asbestos free. No chemical binder is added. Double-side needling provides blanket with great tensile or handling strength for easy installation. Blankets are available in various classified temperatures from 1260C to 1430C.
Ceramic fiber blanket is resistant to most chemicals attack except hydrofluoric, phosphoric acid and high pH alkali (Na2O or K2O). Its thermal and physical properties cannot be affected by oil, steam and water.
Advantages
- Heat resistance
- Light weight
- Low thermal conductivity
- Flexible
- Resilient to thermal shock
- High tensile strength
- Corrosion resistance
- Easy to install Asbestos free
Applications
- Petrochemical process heater refractory fiber lining
- Heat treating furnace or Intermittent (shuttle) kiln hot face lining
- General furnace backup insulation
- Heat seals for kiln car or furnace door
- Electrical insulator
- High temperature acoustic
- Fire protection
