202 Type II styrene series strongly basic anion exchange resin
1. Description
202 is a sort of anion exchange resin that has quaternary ammonium group [N-(CH3)2C2H4OH] in the styrene-diethylene benzene copolymer. It is used mainly to produce pure water with the characteristics such as high regenerated efficient and large exchange capacity and so on, especially suitable for the water resource with high content of salt.
