Alumina filler has a high strength, high temperature, high pressure, strong acid-base corrosion-resistant, good thermal shock resistance and so on.

Mainly used in chemical industry, high temperature, high pressure, corrosion of the working environment.

As the reactor catalyst support material covering and packing, it can withstand acids, alkalis and other organic solvents in the production process of corrosion and temperature changes occur.

Its main role is to increase the gas or liquid distribution points, support and protect the strength is not high activity catalyst.
