LH-007 strongly acidic styrene type cation exchange resin

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．
