2025 Top 10 Aluminum Sulfate Flake Manufacturers in the world

Introduction to Aluminum Sulfate Flake

Aluminum sulfate flake is a white crystalline solid with a wide range of applications. Chemically, its formula is Al₂(SO₄)₃. It is soluble in water and has acidic properties in aqueous solutions.

In the water treatment industry, it is a commonly used coagulant. When added to water, it can neutralize the charges of suspended particles, causing them to aggregate and settle, thus effectively removing impurities and turbidity from water. This makes it an essential chemical in both municipal water treatment plants and industrial wastewater treatment facilities.

In the paper - making industry, aluminum sulfate flake is used as a sizing agent. It helps to improve the water resistance, strength, and printing properties of paper. It also plays a role in adjusting the pH of the papermaking process, which is crucial for the quality of the final paper product.

In the textile industry, it is used as a mordant. A mordant helps to fix dyes to fabric fibers, enhancing the color fastness of dyed textiles. Additionally, it has applications in the production of fire - retardant materials, tanning, and as a pH regulator in various chemical processes.

Now, let's take a look at the top 10 aluminum sulfate flake manufacturers in the world in 2025.
