■Protection Tube, Insulating Tube, Thin Tube

Our lineup includes alumina, which can be used up to a maximum operating temperature of 1,850℃, as well as mullite, zirconia, and magnesia materials, all boasting excellent corrosion resistance.
They are suitable for use in all types of heat treatment furnaces.

■Features

  1. Superior heat resistance, allowing them to withstand the required high temperatures and maintain excellent gas-tightness.
  2. Excellent high-temperature strength and thermal shock resistance.
  3. Superior creep resistance, resulting in minimal change at high temperatures.
  4. Chemically stable and highly corrosion resistant.
  5. Low dielectric constant and excellent electrical insulation properties.
  6. Good temperature responsiveness.
