Unifrax Fiberfrax® Fibermat® Blanket Ceramic Fiber Insulator
Categories: Ceramic; Oxide; Aluminum Oxide; Silicon Oxide

Material Notes: Fiberfrax Fibermat is a lightweight, high-strength needled insulating blanket. The blanket fibers are spun from a ceramic composition having a normal use limit of 760°C (1400°F). Fibermat is completely inorganic and derives its exceptional strength from the needling of long ceramic fibers. It has excellent thermal and acoustical insulating properties.

    Typical Applications
  • Acoustical insulation
  • Thermal insulation for external applications
  • Insulating pads
