201*7 Strong-base Stryrene Serial Anion Exchange Resin
1.Brief Introduction:
this product is the cation exchange resin that is sulfonated styrened 7% styrene copolymer. It is mainly used for softening hard water and pure-water preparation and also used for hydrometallurgy, sugar making, pharmacy, and monosodium glutamate. It can be used as catalyst and dehydrating agent too.
