Lewatit® MonoPlus S 108 H is a strongly acidic, gelular cation exchange resin with beads of uniform size (monodisperse) based an a styrene-divinylbenzene copolymer, in fully regenerated form (min. 99% H). Due to a special manufacturing process this resin type is extremely resistant to chemical, osmotic and mechanical stress. That leads to very low leachables even under critical conditions like higher temperatures, presence of oxidants (02, Fe-oxides) and external regeneration processes. Even at very short cycle times (one cycle = service + regeneration) the special ion exchange resin matrix leads to long life cycles in demineralization processes.
