Description
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.
