Microtherm Group Board Filament Reinforced Pyrogenic Silica Thermal Insulation
Categories: Ceramic; Oxide; Silicon Oxide; Other Engineering Material
Material Notes: Microtherm® Board is a high performance thermal insulation made at a lower density than normal Microtherm products. The insulation is an opacified blend of filament reinforced pyrogenic silica, specifically blended for toughness and optimized manipulation.
    Properties
  • Low density high temperature thermal insulation
  • Stable thermal performance for continuous exposure to 1000°C (1832°F)
  • Excellent machineability
  • Non combustible
  • Environmentally safe
  • Free of harmful respirable fibers
    Applications
  • Thermal batteries - rapid heat up
  • Space and Aerospace - lower weight
  • Portable fuel cells - easier to carry
  • Furnaces - easy installation
