Thermal Ceramics Kaowool Wet Felt
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: Thermal Ceramics Kaowool Wet Felt is manufactured by combining Kaowool ceramic fiber with an inorganic bonding agent. It is very pliable with good green strength. Wet Felt may be cut into any size or shape, or it may be formed or molded. It will conform to any surface or contour. When dried or fired, it becomes a lightweight resilient insulator which can be sawed, cut, or sanded. It will not crack or spall or be wet by molten aluminum.

Kaowool Wet Felt is a highly efficient insulator. Its longer fibers give it the high tensile strength and resiliency to withstand vibration and physical abuse. Kaowool Wet Felt has low thermal conductivity, low heat storage, and is extremely resistant to thermal shock.

Features:

  • Highly efficient insulator
  • Good green strength and may be formed or molded
  • Completely inorganic
  • Applications:

  • Line trough and areas contacted with molten aluminum
  • Interior of dryers
  • Curved areas in ovens
  • Insulation for pipe wrap
  • Information provided by Thermal Ceramics
