Product Details

Lanlang ® TC007B Is a premium grade gel type strong acid cation exchange resin produced by sulfonated styrene-divinylbenzene (DVB) copolymers in standard Gaussian size distribution. Its dark color makes it it convenient to be separated from anion resin in mixed bed. It has excellent chemical, physical and thermal stability. TC007B in sodium form is widely used for water softening to reduce total hardness. In hydrogen form, it also can be used for water demineralization.
