Strong Acid Cation (SAC) Exchangers

Strong Acid Cation resins are used for domestic and industrial softening (in Na⁺ form) and demineralization (in H⁺ form). All of them are based on a polystyrenic matrix which bears sulfonic functional groups.

Gel type resins have a homogeneous structure, with only micropores inside the beads: they have fast kinetics and a high operating capacity and they are the products of choice for most conventional applications.

Macroporous resins have pore structures significantly more robust than gel resins that allow macroporous resins to be used in more challenging applications and in harsher operating conditions. Macroporous resins are in fact more osmotically and oxidatively stable and less prone to mechanical breakdown.

Like most Purolite products, our strong acid cation ion exchange resins are available in several ionic forms and in many size gradings including uniform particle size. They are available with many types of regulatory approvals such as NSF Certified, Kosher and Halal.
