1. Brief Introduction：
this product is the cation exchange resin that is sulfonated styrened 7％ styrene copolymer．It is mainly used for softening hard water and pure-water preparation and also used for hydrometal-lurgy，sugar making，pharmacy，and monosodium glutamate．It can be used as catalyst and dehydrating agent too．
This resin series include three types，among which LH-007 is a general one：LH-007 FC is for strata bed，double bed，fluidized bed system；LH-007 MB for mixed bed system．
