Q1: What is the primary functional group and matrix type of LEWATIT MDS TP 260?
A: LEWATIT MDS TP 260 is a macroporous, strongly acidic cation exchange resin based on a styrene-divinylbenzene copolymer matrix, functionalized with sulfonic acid groups. Its macroporous structure provides enhanced kinetic performance and stability in non-aqueous or low-ionic-strength environments.
Q2: In which types of industrial processes is this resin most commonly applied?
A: It is widely used for selective removal of multivalent cations (e.g., Ca²⁺, Mg²⁺, Fe³⁺, Cu²⁺) in demanding applications such as pharmaceutical water polishing, fine chemical synthesis, catalyst recovery, and purification of organic process streams where gel-type resins may exhibit limited capacity or fouling resistance.
Q3: How does LEWATIT MDS TP 260 differ from conventional gel-type cation exchangers?
A: Unlike gel-type resins, MDS TP 260 features a rigid, permanently porous structure that maintains high exchange capacity and mechanical stability across varying pH, temperature, and solvent compositions—including mixed aqueous-organic media. This makes it especially suitable for applications involving intermittent flow, high solids content, or aggressive regeneration conditions.
Q4: What are key handling and storage recommendations?
A: Store in original sealed packaging at temperatures between 5 °C and 40 °C, away from direct sunlight and oxidizing agents. Avoid freezing. Prior to use, rinse thoroughly with deionized water or appropriate pre-treatment solution to remove fines and residual manufacturing agents. Always follow site-specific safety protocols when handling dry or spent resin.
