Thermal Ceramics Kaowool 1401 Millboard
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: Kaowool 1401 Millboard is a strong, thin, dense board product with excellent compression resistance and insulating characteristics. It is produced from Kaowool ceramic fibers, clay, inert fillers, and a small amount of both organic and inorganic binders for increased handling strength. It maintains its integrity throughout a wide temperature range and is easily fabricated and die cut. Kaowool Grade 1401 Millboard is an excellent product for backup insulation and many types of gasketing applications.

Features:

  • Asbestos replacement millboard
  • Thin durable insulation and gasketing
  • Easy to die cut
  • Good compression resistance
  • Excellent dimensional stability
  • Excellent backup insulation
  • Applications:

  • High-temperature gaskets
  • Heat and flame shields
  • Parting media
  • Thermal barrier
  • Refractory backup insulation
  • Information provided by Thermal Ceramics
