Since 1985, Hanchag has contributed on environment protection and energy saving by producing

Molecular sieve for O2-VPSA
Absorbent for absorption chiller


Together with Humans

Hanchang’s molecular sieve is the key component of O2-VPSA which is essential to steel, smelting and glass industry. Our LiBr absorbent is the key material for absorption chillers which significantly save electricity for cooling and heating.



Pigments for anti-corrosion paints
protecting steel structures


Protecting the World

What if an expensive oil platform that has to withstand ocean wind and wave corrodes? It will soon
disintegrate and the environment will be contaminated. Hanchang’s anti-corrosion pigments play essential role in protecting the world.



Electrolytes for flow batteries that
store electricity economically


Contribution to Future Energy

Hanchang’s high purity electrolytes are the key materials for flow batteries which contribute efficient and clean production of electricity by storing electricity from renewable sources or from grid during the night and releasing it during the peak time
