201x2 is a kind of anion exchange resin with quaternary ammonium group [- n (CH3) 3OH] on the 2% styrene divinylbenzene copolymer. Its basicity is equal to that of ordinary quaternary amine base, and it shows ion exchange function in acid, neutral or even basic medium. The product has good mechanical strength and high heat resistance. It is mainly used in pure water and high purity water manufacturing, sugar solution decolorization, wastewater treatment, extraction of biochemical products and radio elements, etc.
