Giving the Gift of Warmth and Insulation with a Ceramic Blanket
Giving the Gift of Warmth and Insulation with a Ceramic Blanket
December 07, 2017

Commonly used as furnace or kiln lining, the ceramic blanket is an insulation tool constructed of spun ceramic fibres intricately needled together for outstanding durability. It is preferred for quick repairs as unlike many insulation materials, it requires no curing or drying cycle.


With its ability to resist thermal shock, a ceramic blanket is used in a variety of high temperature processes including, but not limited to:


  1. Furnace lining and sealing
  2. Pipe, duct and turbine insulation
  3. Boiler insulation
  4. Sealing and covering
  5. Fire protection


It can withstand environments with temperatures ranging from 1260°C to 1650°C with an insulation value five times better than hard insulation materials.


At FibreCast we offer a ceramic blanket in a variety of chemistries, densities and thicknesses. With four types of ceramic blankets to choose from, we guarantee you will find a material to fit your operation.


Bio Soluble

Soluble in body fluid, a bio soluble ceramic blanket reduces damage to workers handling the module. However, despite being made of alkaline earth silicate fibre derived from a chemistry of calcium, magnesium and silicate, this type of material can be used in high-temperature environments up to 1260°C.


FibreCast’s selection includes two kinds of bio soluble blankets, isofrax and insulfrax. The former exhibits low thermal conductivity while retaining excellent thermal stability. It has superior corrosion resistance as well as flexibility. It can be used in applications that involve temperatures up to 1260°C.


Meanwhile, insulfrax blankets are made of needled fibres. The module is harder than its isofrax counterpart but is still lightweight and flexible. With this material, workers have no need to use binders, resulting in exceptional tensile strength. Isofrax modules do not generate smoke when exposed to heat as they are completely inorganic. They can withstand temperatures up to 1260°C.


High Purity Ceramic Fibre

If corrosion is your main concern, a high purity ceramic fibre blanket is recommended because of its superior resistance to chemical reactions. Composed of fibre developed from alumina-silica materials, this module offers stable insulation in heated environments of up to 1260°C.


Zirconia Fibre

Ideal for ceramic and iron processing, zirconia fibre blankets provide outstanding backup insulation in high-temperature application involving heat up to 1430°C. The module, created using alumina-silica-zirconia fibres, has low shrinkage while remaining stretchable and durable.


Maftec/Polycrystalline Mullite

Among the four modules, the maftec or polycrystalline mullite exhibits the most superior chemical stability ensuring low shrinkage and excellent resiliency in environments with temperature up to 1650°C. Over time, this insulation material stays intact which translates to cost savings on fuel and maintenance, as well as minimized gaps between modular linings.


This type of ceramic blanket can be used to form stack-bonded and composite modules for factory-grade kilns, furnaces and heaters.
