CERAMIC BLANKET 2017-09-15T14:06:02+00:00

Ceramic Blanket

All three grades of blanket have the same excellent chemical stability compared with their raw materials. They have excellent strength before and after heating. They have superior acoustic as well as thermal insulation characteristics. The wide range of available densities and thicknesses 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.

Performance: Excellent insulating performance.
Unaffected by Most Chemicals: Unaffected by most chemicals except hydrofluoric and phosphoric acids and strong alkalises.
Thermal Stability: Excellent thermal stability: fibers have good resistance to diversification.
Resistance: Resistance to thermal shock.
Sound Absorption: Good sound absorption.
Product Range: Available thickess is 13, 25 and 50mm.

Lightweight, low thermal conductivity, high temperature stability, excellent handling strength, low heat storage, thermal shock resistant, fire and flame proof, chemical resistant, compatible with most corrosive chemicals, commonly used acid and alkali (exceptions are hydrofluoric, phosphoric acids and concentrated alkalis).

Chemical Composition: Al2O3 + SiO2 >97% ( Al2O3 47%);
Fe2O3< 1%

Fibre Diameter: 3 – 4.5 microns.
Fibre Shrinkage: 5% at 1500°C.
Working Temperature : 1100 °C  for continuous Use, 1260 °C maximum.
pH Range: 2-12.

  • Density:  64, 96, 128 kg/m3.
  • Thickness: 1/4″, 1/2″, 1″, 1-1/2″,2″ Width: 24″ and 48″.
  • 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.
