Refractory Ceramic Fibre

Ceramic Fiber Blown Bulk


  • Filling sealing and insulation at high temperatures(kiln car, pipeline, kiln door, etc.)
  • Composite material in fiber industry( friction plate, etc.)
  • Expansion joint filler material for firebricks and castable.
  • Filler for short time insulation.
  • Thermal insulation filing material for small corner.
  • Raw materials for ceramic fiber further processing products.


    Ceramic fiber blown cotton is made by melting high-purity raw materials at high temperature and using blowing method. The product has uniform diameter and white color.The physical property like refractory and insulation keep same when meet with oil,water or steam.

    Ceramic fiber blanket/ felt/ board/ paper/ cloth/ rope and other ceramic fiber products can be produced by bulk through further processing. Hengrui ceramic fiber bulk is a kind of insulating materials which has these characteristics, such as light-weight, anti-oxidation, low thermal conductivity, softness, anti-corrosion, low heat capacity, sound insulation and so on.
