Ceramic band heater steatite insulation parts Alumina strips

Ceramic band heater steatite insulation parts Alumina strips

1 hole – 12 holes ceramic strips for ceramic band heaters

Material:

  1.  white steatite
  2.  pink alumina

Description:

Ceramic band heaters are structured with high-quality resistance wires(such as nichrome wires or Fe-Al-Cr alloys) embeded within ceramic strips. The ceramic strips are installed within the outer cover selection of stainless steel.

The middle of the selection of high-temperature ceramic fiber insulation, which effectively avoids the temperature leakage.

Ceramic band heater is a high-frequency ceramics, which has the advantages of fast heat transfer efficiency, hard and not easily broken, high-temperature deformation, not easy to aging.
