201x4 is a high capacity, shock resistant, gelular,Type I ,strongly basic anion exchange resin.
| For Efficient Demineralibation Including Silica Removal201x4 is a high capacity, shock resistant, gelular,Type I ,strongly basic anion exchange resin supplied in the chloride or hydroxide form as moist, tough, uniform, spherical beads. 201x4 is intended for use in all type of deionization systems and chemical processing applications and is especially suited for use in regenerable mixed beds. it also shows good kinetics of exchange, enabling very low concentration levels of both strong and weak acid anions to be achieved at practical flowrates. |
