Cation exchange resin SR1L
SR1L Na is a gel-type strongly acidic cation exchange resin used for water softening. SR1L Na resin has excellent physical and chemical stability, good exchange kinetics, and high exchange capacity and can be used at elevated temperatures.
During production, the resin undergoes thorough control for compliance with high purity requirements, in particular: physical and chemical properties; release of substances into treated water; total organic matter excretion (TOC), and total microbial content.
SR1L Na is specially designed for softening drinking water and food products and is produced using a special technology that excludes the use of chlorinated solvents. SR1L Na resin is supplied in a free-flowing form which makes filling filters and cartridges very easy and quick.
SR1L Na is insoluble in dilute solutions of acids or alkalis and common organic solvents.
