201×7(717)Styrene series strongly alkaline anion exchange resin
1. Description
This is a kind of anion exchange resin which has quaternary ammonium group [-N(CH3)3OH] in the styrene-divinylbenzene copolymer with the crosslinkage of 7%.Its alkalinity is similar to the general quaternary ammonium base.It can be used as ion exchanger in acidic,neutral and alkaline mediums. This product has good physical strength, high heat resisting property etc.
This product is analogous to: Amberlite IRA-400; SA-10A; Dowex SBR; Purolite A600
