Lanlang ® TC008FG Is a premium food grade gel type strong acid cation exchange resin produced by sulfonated styrene-divinylbenzene (DVB) copolymers in standard Gaussian size distribution. TC008FG is in compliance with US FDA 21 CFR 173.25 and NSF/ANSI 61 qualified with WQA Gold Seal Certificate. It has excellent chemical, physical and thermal stability, and high exchange capacity. Its good ion exchange kinetics gives high efficiency for uses in both regenerable softeners and non-regenerable cartridges.
