Lanxess LEWATIT® UltraPure 1213 MD Cation Exchange Resin
Categories:	Polymer; Thermoset
Material Notes:	Lewatit® UltraPure 1213 MD is a gel type, strongly acidic cation exchange resin (SAC) with a monodispersed bead (uniform particle) size distribution based on a styrene-divinylbenzene copolymer for the use in WS/VWS system for the production of ultra pure water. The monodisperse beads (uniformity coefficient: max 1.1) are chemically and osmotically highly stable. The optimized kinetics lead to an increased operating capacity and the very low content of fines also results in a low pressure drop compared to ion exchange resins with heterodisperse bead size distribution. Lewatit UltraPure 1213 MD is highly regenerated and specially cleaned to meet the specifications for the semiconductor industry. Leaching of organics from Lewatit UltraPure 1213 MD into the treated water is reduced to a level less than 10 ppb, and its resistivity achieves a level higher than 12 MOhm*cm if being used as a single component. An optimized combination of Lewatit UltraPure 1213 MD and Lewatit UltraPure 1243 MD excellently performs in polishing mixed bed systems for a further on low release of Toc and a high resistivity.
