Felite™ FA127-U is a high capacity, uniform mesh, shock resistant, gel, Type I, strong base anion exchange resin supplied in chloride form, with both high operating capacity and the ability to achieve low residual silica levels.

Felite™ FA127-U is intended for use in all types of deionization systems and chemical processing applications. It is similar to Felite™ FA124 but has a higher volumetric capacity and exhibits lower TOC leach rates. This makes it the better performer in single-use applications such as in cartridge deionization and when high levels of regeneration are used such as in polishing mixed beds.

On the other hand, Felite™ FA127-U is more resistant to organic fouling and gives higher operating capacities at low regeneration levels such as those used in make-up demineralizers.
