330 Epoxy Series And Phenolic Aldehyde Series Ion Exchange Resin
1. Description
This product is a weakly alkaline anion exchange resin with primary amine, secondary amine, tertiary amine and quaternary amine (-NH2, =NH, =N, =N-) made by polycondensation of chlorinated propylene oxide and polyethylene polyamine at high temperature. It shows ion exchange function in acidic, neutral and even alkaline. It is characterized by high total exchange capacity and fast exchange rate.
The original grade of this product, 701 and 331, is equivalent to DUolite A-30B from France.
2. Executing standard:GB/T 13659-2008DL/T519-2004
