Q1: What is the primary functional group and ionic form of LEWATIT MonoPlus TP 214?
A: LEWATIT MonoPlus TP 214 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 use in pharmaceutical or food-grade water treatment systems?
A: Yes — LEWATIT MonoPlus TP 214 is designed for high-purity applications and complies with global regulatory expectations for ion exchange resins used in pharmaceutical water systems (e.g., WFI and PW) and food-contact water processing, subject to proper validation and regeneration protocols.
Q3: How does TP 214 differ from conventional gel-type strong acid cation resins?
A: TP 214 features a uniform particle size distribution and highly spherical beads, which improve hydraulic performance, reduce pressure drop, and enhance regeneration efficiency compared to standard gel-type resins. Its optimized crosslinking also supports consistent kinetics and mechanical stability under repeated cycling.
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 oxidizing agents. Avoid freezing, as ice formation may damage bead integrity. Once opened, keep moist and use within a reasonable timeframe to prevent microbial growth or dehydration.
