LH-202 Macroporous Strongly Basic 11 Type Styrene Anion Exchange Resin

1. Brief Introduction:
The product is a type of anion exchange resin with the quaternary amidocyanogen [-N(CH₃)₂, C₂H₄OH] on macroporous styrene-divinyl benzene copolymer which is used in preparation for purity water with characteristics of high reproducibility, big exchange capacity , better pollution resistance ,especially for seriously polluted water.
LH-202 resin series include three types: LH-202 for fixed bed system, LH-202FC for double room and fluidized bed system, LH-202SC for bunk bed system.
