Lanxess LEWATIT® MonoPlus SM 900 KR Ion Exchange Resin
Categories: Polymer; Thermoset

Material Notes: Lewatit® MonoPlus SM 900 KR is a ready-to-use non-separable mixed bed resin comprising strongly acidic gel-type cation and strongly basic (type I) gel-type anion exchange resin in highly regenerated form (min. 99% H/ min 95% OH) Lewatit MonoPlus SM 900 KR is a 1:1 stoichiometric mixture (other mix ratio available on request), premium grade and purified (extremely low content of desorbable chloride ions and no organically bound chlorine) to meet nuclear industry specifications. Lewatit nuclear resins (Lewatit KR) are noted for their outstanding mechanical and chemical stability as well as their high osmotic stability. This non-regenerable mixed bed resin is used in radioactive water circuits, providing a number of special tasks like drastically reduced separability (no reclassification, reduced sulfate leakage) and smaller cation resin bead diameter (330 microns) with uniform bead size distribution (uniformity coefficient: max 1.1). Lewatit MonoPlus SM 900 KR is particularly suitable for the:
  • polishing in the primary sections of RBMK reactors
  • polishing in the secondary sections of boiler water reactors (BWR)
  • decontamination of circuits in nuclear reactor plants
  • one way cartridges
