Polyamine Type DIAION™ WA20, WA21J
WA20 and WA21J do not have any neutral salt splitting capacity. They have a high total exchange capacity and high regeneration efficiency. The porous styrene polymer imports high chemical stability, high mechanical strength against attrition loss, high thermal stability, and high durability against organic fouling.
These resins are used for the removal of strong mineral acids in standard water treatment applications. They can also be applied in special process separations such as the treatment of organic solvents.
It should be noted that WA21J has a highly porous structure and provides excellent mechanical strength for more rigorous industrial applications.
