201×4（711）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. 201×4（711）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.

201×7（717）is a clear gel Type 1 strong-base anion exchanger with both high operating capacity and the ability to achieve low residual silica levels. It has a clear gel structure, showing excellent regeneration efficiency and rinse characteristics. 201×7（717）has exceptional physical stability for a conventional gel-type resin which permits a long life without the development of excessive pressure drop; it also shows good kinetics of exchange, enabling very low concentration levels of both strong and weak anions to be achieved at practical flowrates.

This product is similar to 201×7 Strong-Base Type I (Gel) Anion Exchange Resin, but provided with better physical and chemical stability. It has strong capabilities of permeation resistance, abrasion resistance and contamination resistance. For it has macroporous structure, and can exchange big-sized ions and molecules, so it can be used in non-aqueous medium.

D213 is a sort of anion exchange resin which has quaternary ammonium group [-N(CH₃)₃OH] in the cross linking crylic acid framework with macroporous structure. It is used mainly as the organic substance removing matter as well as absorb resin in decolorization .

P213 is a high capacity, organic fouling resistant, gelular, acrylic Type I. Strongly basic anion resin. Supplied in the chloride or hydroxide form as moist, tough, uniform spherical beads. P213 is intended for use in all types of deionization systems and chemical process applications. Where water temperature do not exceed 40^oC

P200 is a high capacity, gelular, Type II strongly basic anion exchange resin supplied in the chloride form as moist, tough, uniform spherical beads. It provides superior regeneration efficiency and greater resistance to organic fouling than Type I strongly basic anion exchange resins. P200 is intended for use in all types of dealkalization, deionization and chemical processing applications.
