CERAMIC BLANKET

The Ceramic Blanket has the same excellent chemical stability compared with its raw materials. It has excellent strength before and after heating. It has superior acoustic as well as thermal insulation characteristics. The wide range of available densities allow for the most effective deployment of the superior thermal characteristics in a wide variety of applications.

 

 

Technical Data

  • Furnace and kiln linings.
  • Boiler insulations.
  • Heat treatment temperature control.
  • Glass furnace crown insulation.
  • Furnace door seals.
  • Duct linings.
  • Pipe insulations.
  • Thermal barriers for automotive industry.
  • Fire protection.
  • Die cut shapes for domestic applications.
  • Insulation for field stress relieving of welds.
  • High temperature filter media.
  • Nuclear insulation applications.
  • Steam and gas turbines insulation.
  • For some applications, it is possible to use Ceramic Blanket above its classification temperature (shrinkage is 5% at 1500°C).
  • Low heat storage.
  • The combination of long spun fibres and the needing operation produce tough, resilient and strong blankets which resist tearing both before and after heating.
PerformanceExcellent insulating performance
Unaected by Most ChemicalsUnaffected by most chemicals except hydrofluoric and phosphoric acids and strong alkalines.

  • Fiber Diameter: 3 – 4.5 microns
  • Fiber Shrinkage (1800°F, 3h): < 3.5%
  • Working Temperature: 1,800 °F. for Continuous Use, 2300 °F Maximum
  • Specific Heat (@2000°F): 0.27 Btu/lb °F
  • pH Range: 2-12
  • Density: 4, 6, 8 lbs./cu. ft. (64, 96, 128 kg/m3)
  • Thickness: 1/4", 1/2", 1", 1-1/2",2" Width: 25mm and 50mm
  • It is highly unlikely that the products will cease significant amounts of dust during normal handling.
  • Dust control measures will rarely required in circumstances involving the fabrication of products from the material.
  • However according to good working practices the production of debris should be minimized. Use suction where possible to collect dust.
  • Clean waste with HEPA filter vacuum cleaner.
  • Observe emission limits. (See Section 8) store in a dry place.
