Cation Resin, an Ion-exchange Resin for Softener, is primarily used in softener systems to remove calcium (Ca²⁺) and magnesium (Mg²⁺), the main culprits of temporary hardness in water. By exchanging these ions with sodium, this resin ensures softened water, which is crucial for preventing scaling and improving water quality in industrial processes.

Main Use: Softens water by removing calcium and magnesium ions, preventing scaling in water systems.
