BuraGlas HT-SI 9486


BuraGlas HT-SI 9486 is made from high quality silicic acid yarn capable of withstanding extremely high temperatures. The silicid acid fibers are diagonally braided and impregnated. This is augmented by a special impregnation which gives optimal density resulting in excellent sealing characteristics. This compound is excellent for static applications in boilers, furnaces or heat exchangers. Also for thermal insulation.


  • Extremely high temperature resistance
  • Excellent physical properties
  • High mechanical strength
  • Good chemical resistance
  • Optimal density
  • Excellent sealing characteristics (tightness)

Operating range

Pressure: p = 0 ... 10 bar (0 ... 145 PSI)
t = -50 ... +1,100 °C (-58 °F ... 2,012 °F)
Chemical resistance: pH = 5 … 9


BuraGlas HT SI is made from non ceramic, high temperature resistant fibers ≥ 9 microns which eliminates the risk to health and it is harmless to the respiratory system and therefore is not classified as harmful according to WHO and EU regulations 97/96/EC, 67/548/EEC and TRGS 905.
