Poly aluminium chloride is a high‑molecular‑weight inorganic polymer featuring excellent cementitious bonding performance. It works as a reliable binder widely applied in refractory coatings, ultra‑pure alumina products and refractory concrete materials. Classified as a multivalent polyhydroxy electrolyte, it represents the intermediate substance formed during the hydrolysis process from aluminium chloride to aluminium hydroxide. Its colloidal nucleus carries positive charges, and its hydrolysis derivatives exhibit acidic properties.

Polyaluminium Chloride (PAC) functions as a high‑efficiency flocculant for the purification of drinking water, industrial process water and various wastewater streams. It delivers reliable performance for sludge dewatering treatment. Beyond water‑treatment scenarios, it covers multiple industrial sectors: it serves as a sizing agent within the papermaking industry, and is also applied in pharmaceutical manufacturing, sugar refining, and acts as a functional catalyst carrier.
