Thermal Ceramics Kaowool 830 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.

Kaowool Millboard Grade 830 was specifically designed for use in the iron and steel industry as a molten contact product. Kaowool Millboard Grade 830 has proven to be excellent for use as a one shot casting mold liner for both stools and ingot molds because of the unique combination of organic and inorganic binders. This 40 pcf (641 kg/m3), 0.16" (4 mm) product produces an exceptionally smooth surface finish of cast metal pieces when compared to those surfaces produced by sand casting and other board products. Millboard products can be easily die cut into various shapes by the end user or can be supplied die cut to suit a specific application.

Features:

  • 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:

  • One-shot casting mold liner for stools and ingot molds
  • Molten metal contact applications in the iron and steel industries
  • Molten metal contact applications in the non-ferrous industries
  • High-temperature gaskets
