Thermal Ceramics Kaowool 822 Millboard
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: Thermal Ceramics Kaowool Millboard products are processed from a slurry consisting of Kaowool ceramic fibers, fillers and binders. The fiber raw material is Kaolin, a naturally occurring high-purity alumina-silica fireclay. Kaowool Millboard products are strong, thin, durable ceramic fiber based boards having a variety of high-temperature applications. Although these products were formulated and designed to replace asbestos millboard, their potential use extends into more conventional refractory fiber applications. Their use should be considered whenever there is a need for a thin, durable board with excellent insulating characteristics.


  • Asbestos replacement millboard
  • Thin durable insulation and gasketing
  • Easy to install
  • Thickness tolerance of ± 0.0315" (0.7875 mm)
  • Suitable for saw or die cutting
  • Excellent backup insulation
  • Grade 830 excellent for molten metal contact applications
  • 2000°F to 2700°F (1482°C) use limits
  • Applications:

  • High-temperature gaskets
  • High-temperature roll covering
  • Fire protection
  • Thermal barrier
  • Backup insulation in rotary kilns
