SILICA BLANKET TYPE SB-2000

GENERAL INFORMATION

ZIRCAR Silica Blanket Type SB-2000 is a high temperature insulation blanket made of mechanically interlocked continuous filament amorphous silica fibers with useful properties to temperatures of 1100°C (2012°F).

SB-2000 is a strong needled blanket with very good handling properties. It is virtually shot free and has high resistance to attack by most chemicals. Exceptions include strong bases and hydrofluoric acid. This blanket exhibits thermal shock immunity, thermal conductivity and heat storage in the range of refractory ceramic fiber (RCF) blanket and is useful in many applications where RCF is not desired.

SUGGESTED APPLICATIONS

  • Annealing Cover Seals.
  • Flexible High Temperature Pipe Insulation.
  • Furnace, Kiln, Reformer and Boiler lining.
  • Furnace Door Linings and Seals.
  • Investment Casting Mold Wrap.
  • Expansion Joint Seals.
  • High Temperature Filtration.
  • Nuclear Insulation Applications.
  • Glass Furnace Crown Insulation.
  • Useful When Refractory Ceramic Fiber Are Not Desired.
  • Thermal Reactor Insulation.
  • Soaking Pit Seals.
  • Reusable Insulation For Field Stress Relieving Welds.
  • Insulation For Primary Reformer Header.
  • High Temperature Gasketing.
  • High Temperature Kiln and Furnace Insulation.
  • Fire Protection For Pressure and Cryogenic Vessels.
  • Lining For Incineration Equipment and Stack.
