D301 Macroporous Weak Alkaline Styrene Series Anion Exchange Resin
This product is a type of weak alkaline ion exchange resin which is consisted by styrene- divinylbenzene copolymers with tertiary amine group [-N(CH3)2]of macroporous structure.Due to the relative weak alkaline,the product can eliminate organic pigment,inorganic acid or silicate and adsorb impurities constituted by molecules of large size in acidic and near neutral medium effectively as well as be applied in non-aqueous solution.This resin has properties including high regeneration efficiency,large exchange capacity,strong stain resistance and excellent mechanical strength.Original designation of this product refers to D370 and D354,which are equivalent to Amberlite IRA-93 in the US.
