Felite™ FA201 is a highly efficient and durable, Type I macroporous strong base anion exchange resin with quaternary ammonium as the functional group. Its macroporous structure provides high operating capacity and excellent regeneration efficiency and allows complete removal of all anions, including weakly dissociated ions such as silica. This structure with strong basicity also permits the removal of large size soluble organic molecules and imparts superior resistance to mechanical and osmotic shock.

Felite™ FA201 is especially well suited for high flow rate and high-temperature polishing applications. It can also be used for uranium complexes extraction and gold sorption while is supplied in specially coarse mesh bead size(Felite™ FA201-C).

Felite™ FA201 is available in the chloride form or in the hydroxide form.

Principal Application:
Silica Removal;
Mixed Bed Anion Component;
Acid Retardation;
Condensate Polishing;
