Anionic Resin

Pure Ion AX-7000

is a high-capacity premium grade bead form conventional gel polystyrene sulfonate. This resin is ideal for use in industrial or household water conditioning equipment. It possesses similar acidity levels to inorganic acids like sulfuric acid (H2SO4) and hydrochloric acid (HCl). The resin can function as an ion exchanger in alkaline, neutral, and acidic environments, showcasing rapid exchange capability and strong physical durability.
