While Polyaluminium Chloride (PAC) is predominantly recognized for its efficacy in water and wastewater treatment, its versatile chemical properties lend themselves to a surprising array of industrial applications. Beyond its role as a coagulant, PAC serves crucial functions in sectors ranging from paper manufacturing to personal care products. Understanding these diverse uses can highlight the broad utility and value of this inorganic polymer.

In the paper and pulp industry, PAC acts as a sizing agent and a retention aid. It helps improve the paper's resistance to water penetration and retains fine particles and fillers within the paper matrix, leading to better quality paper products. Its effectiveness in wastewater treatment within this industry also aids in managing effluent streams.

The oil and gas industry utilizes PAC for its properties as an oil-water emulsion destabilizer. In oil refining processes, crude oil often contains water, which reduces its commercial value and complicates refining. PAC helps break these emulsions, facilitating better separation of oil and water, thereby improving operational efficiency and product yield.

Furthermore, PAC finds its way into the cosmetics and personal care industry, particularly in antiperspirants and deodorants. Its astringent properties help to reduce sweat production by forming temporary plugs in the sweat ducts. This application leverages PAC's ability to interact with proteins and form a gel-like barrier on the skin.

Other notable industrial applications include its use as a hardener in concrete and casting materials, and in the textile industry as a mordant or fixing agent for dyes. The adaptability of PAC, stemming from its unique chemical structure and high charge density, allows it to perform critical functions across various manufacturing processes. When seeking reliable industrial chemicals, consider purchasing PAC for its multifaceted benefits. Exploring these varied applications underscores the importance of PAC as a key industrial chemical, extending its value far beyond traditional water treatment.
