Cation Exchange Resin



Description of cation exchange resin :

Strong acid styrene cation exchange resin is Styrene divinylbenzene copolymer with a sulfo radical. Strong acid styrene cation exchange resin has the feature of high exchange capacity, fast exchanging speed, and good mechanical strength.
Strong acid styrene cation exchange resin is equivalent to America Amberlite IR-120, Dowex-50, Germany Lewatit-100, and Japan DisionSK-1.

Structural Formula of cation exchange resin :


Application of cation exchange resin :

Strong acid styrene cation exchange resin is mainly used for water softening, desalted water, pure water and high purity water preparation, the cation exchange resin  also  used for catalyst and dehydrating agent and wet metallurgy, purification of rare element, pharmaceutical, sugar industry, etc.
