Light Weight Mullite Castable

 

1.Product properties and features

  This serie of castable are made from mullite hollow spheres, alumina hollow ball, ultrafine powder, etc. as main raw materials and aluminate cement as main bond. It has the advantages of good thermal insulation properties, high operating temperature and strength, low shrinkage at high temperature, which is suitable for working linings of various industrial furnaces and other high-temperature, energy-conservation parts.
