Q: What grade of Trimesoyl Chloride (TMC) is required for seawater desalination RO membrane synthesis?

A: For thin-film composite (TFC) RO membranes, a high-purity TMC with purity ≥ 99.5% and free acid/trimesic acid impurities below 0.1% is critical to ensure high water flux and salt rejection. We provide polymer-grade TMC specifically optimized for interfacial polymerization
