Supercera Ceramic Fibre Blankets

Supercera Blankets
Supercera Blanket is a refractory fibre needled mat made without binder from Supercera fibres the only super-spun double needled fibre in the country today. Supercera RTZ and HTZ Blankets are zirconoca stabilized and are suitable or use upto 1260°c and 1425°c respectively.

Both blankets have excellent resistance to most chemicals. If wet by oil or water, thermal and physical properties are fully restored upon drying.

Out Standing Advantage

  • Excellent Thermal Stability.
  • Low Shrinkage at elevated temperature - due to their excellent Thermal Stability.
  • Low Heat Storage Both blanket store approximately 95% less heat than dense firebrick and approximately 75% less heat than insulating firebrick a property of significant importance in the operation of periodic kilns / furnaces.
  • Good Cold strength.
  • Excellent Hot strength.
  • Thermal stock Resistance due to the flexible matrix of Supercera, extreme temperature change do not alter its ability to physically stay in place and perform at higher levels.
  • The products are not wetted by molten non-ferrous metals. If wet by oil, water or steam, Thermal and physical properties will be fully resorted after burn out or drying.



  • Normalising Annealing furnaces and glass lehrs.
  • Reformers & Ducts in petrochemical, fertiliser and Boiler Linings Industry
  • Fexible high temperature pipe insulation.
  • Low velocity HRSG and stack linings
  • Glass Furnace crown insulations
  • Trundish cover, Transfer cars in steel plants
  • Soaking pit seals and expansion joint
  • Kilns, klin cars for ceramic industry
  • Annealing cover bottom seals
  • Reusable insulation blankets for field stress relieving of welds
  • Removable Insulation blankets for steam and gas turbines and fire protection.
  • Insulation wrap on investment casting moulds
  • Furnace door seals, linings and gaskets
  • Temporary repair of refractory furnace linings and roofs
  • High temperature filter media / gaskets
  • High temperature sound absorption and Nuclear Insulation applications.

Supercera Boards & Blocks

Supercera Boards and Blocks are made from superspun Supercera fibres by multi component organic / inorganic bonding process.

Supercera Blocks and shapes are obtained by vacuum suction of a mixture of Supercera Ceramica fibres with organic and mineral binders. These vacuum formed products can be moulded and cured into a wide variety of shape to have a smooth inside surface and a rougher outside, as demanded by the application.

Supercera fibre boards, blocks and shapes are self supporting with excellent stability at high temperatures, having high resistance to thermal shock and chemical attack. Supercera fibre boards, blocks and shapes can be rendered machinable to be sawed, drilled or machined, where required.

Density 260 - 320, 720 kg/m3
Size 915 x 600 mm & 1000 x 500mm
Thickness 10-50 mm

Applications (Vacuum formed shapes)

  • Combustion chambers
  • Domestic boiler doors
  • Peep holes, pipe seals
  • Special furnace lining parts
  • Radiant element supports in vitroceramic hotplates (either electric resistance or halogen)


Applications (Boards and Blocks)

  • Linning of : Furance including electric furnaces: Flue and chimney of furnaces and Hot gas ducts: combusting chamber in heating boilers: Glass tank side, end walls, and port neck; Low and high temperature driers
  • Trough and distribution linings for conveying molten metal
  • Refractory backup for bricks and castables.
  • Pouring forms for non ferrous castings
  • High temperature baffles and muffles
  • Heat shield for personnel protection
  • Rigid high temperature gasket and seals
  • Expansions joints.


Supercera Anchored Modules and Veneering Modules
Supercera anchored modules are made from folds of Supercera ceramic fibre the - only superspun doubled-needed fibre in the country. The module is held in compression by removable strapping. Each module has an integral anchoring system - the result of continuous R & D and advanced designing. Fixing of the module to metals shell is achieved by welding specially designed studs, supplied integral with the module, resulting in efficient, fast, and error-free installation. Supercera Modules are ideal for full thickness lining for new furnaces as well as conversion into fibre lining incase of old furnaces. They enhance the furnace life and performance.

Density: 128, 160kg/m3
Thickness: 100- 300mm for anchored and 50- 75mm for veneering.

Supercera veneering Modules improve the thermal efficiency of old brick linings with minimum downtimes for repairs.


  • Reheating Furnaces
  • Bell Anneling Furnaces
  • Soaking pit seals and covers
  • Ladle preheaters
  • Chemical process heaters
  • Incinerators
  • Reformers, etc.


Specially Products
