Dimethylamine Type DIAION™ WA30

WA30 resin is a weak base anion exchange resin based on a high porous, styrene/ DVB polymer matrix. WA30 has tertiary amine functionality with high regeneration efficiency. The high porous styrenic matrix imparts excellent chemical stability, excellent mechanical and osmotic strength (to minimize attrition), high thermal stability, and excellent durability against organic fouling. The high porous matrix of WA30 provides a high reaction rate.

WA30 is the benchmark in which all macroporous weak base anion exchange resins are compared. WA30 is used for a very wide variety of applications, such as removal of organic substances of high molecular weight, pretreatment of raw waters containing organic foulants, deionization, and decolorization of starch hydrolysates (such as corn syrup, dextrose, HFC’s and sugar solutions) and purification of glycerine and enzymes.
