Q1: What is the primary functional group and ionic form of LEWATIT MonoPlus MP 64?
A: LEWATIT MonoPlus MP 64 is a strongly acidic cation exchange resin based on a styrene-divinylbenzene matrix, functionalized with sulfonic acid groups. It is supplied in the sodium (Na⁺) form, making it suitable for softening and selective cation removal applications.
Q2: Is this resin suitable for food-grade or pharmaceutical water treatment?
A: Yes — LEWATIT MonoPlus MP 64 is manufactured and tested to meet requirements for use in the production of potable water and process water in food and pharmaceutical applications, subject to proper regeneration and system validation per end-user regulatory expectations.
Q3: How does MP 64 differ from standard gel-type cation resins in terms of selectivity and kinetics?
A: MP 64 features a uniform particle size distribution and optimized crosslinking, which enhances kinetic performance and improves selectivity for divalent cations (e.g., Ca²⁺, Mg²⁺) over monovalent ions. This results in more efficient softening and reduced regenerant consumption compared to conventional heterogeneous resins.
Q4: What are the recommended storage conditions for long-term stability?
A: Store in original sealed packaging at temperatures between 5 °C and 40 °C, away from direct sunlight and strong oxidizing agents. Avoid freezing, as ice formation may damage the bead structure. Once opened, keep the resin moist and protect from contamination.
