Insulmicanite® products are placed between the coil and the refractories in induction furnaces:

• They protect the coil from mechanical stresses resulting from the expansion and movement of the crucible
• They improve electrical insulation during sintering
• They can be used to adjust the sintering depth and to reduce heat losses from the furnace
• They reduce the risk of perforation when the crucible wears or cracks
• They can be used in the electronic detection of defects in the crucible 
•  They facilitate the removal of a worn crucible.

Insulmicanite® products are available in sheets or on a roll, without a backing or with glass fiber backing on one or both sides, with body soluble fiber to improve thermal insulation and absorb expansion, etc.
