The Strong Acid Cation Exchange Resin is the type of ion exchange resin with functional group of sulfonic acid.

The strong acid cation resin is styrene and divinylbenzene polymer, A polymer prepared by sulfonation of sulfuric acid.When the cation exchange resin is in contact with water, it can exchange one of its own active ions and one of the electric ions in the water, that is, a displacement reaction occurs, to remove the dissolved ions in the water.

The strong acid cation exchange have two types, Gel type and Macroporous type.both of then have excellent chemical and physical and chemical stability.which can operated at PH 0-14. it has good performance even at 100-120 °C.
