Lanlang ® TA207MB Is a premium grade gel type I strong base anion exchange resin with standard crosslinked polystyrene matrix, quaternary amine (Trimethylamine) function group and selected particle size. Its clear gel structure make it has excellent regeneration efficiency (both in co-current and counter-current systems) and rinse performance. Its higher crosslinkage makes TA207MB has higher capacity and better physical & chemical stability. Combining with strong acid cation exchange resin (in hydrogen form), TA207MB in hydroxide form can be used in all types of demineralization system including condensate polishing. The selected size offers high efficiency during back wash process in regenerable mixed bed applications.
