ALERT ceramic fiber blanket is a kind of heat insulation blanket and needle-punching processing can further enhance the tensile strength and flat surface. The fiber blanket does not contain any bonding agent. Ceramic fiber blanket has excellent chemical corrosion-resistant performance. Ceramic fiber blanket is produced with spun and blown technology.It has excellent anti-high temperature performance which can meet demands for the application of heat insulation on various hot faces and cold faces in different furnaces.
Product Characteristics:
* Excellent chemical and thermal stability
* Low Thermal shrinkage
* Excellent tensile strength
* Low thermal conductivity
* Low heat storage
Applications include:
*Boiler and Water heater linings for combustion areas
*Ceramic kiln linings
*Industrial furnace linings
*Backup insulation for castables, brick, etc.
*Usable anywhere high temperature insulation is required
*Materials of module and pucker steatite
* High temperature gasket
