Product Description

201×7MB styrene series strongly basic anion exchange resin

1.Description:

201×7MB is a sort of anion exchange resin that has quaternary ammonium group [-N(CH₃)₃OH] in the styrene-diethylene benzene copolymer with 7% cross linking degree. It is used mainly to produce pure water and ultra pure water in the mixed bed system, with the characteristics such as excellent hydraulics trait and physical stability
