Felite™ FC108-F is a sodium form 8% crosslinked gel strong acid cation resin with a special particle size range, fine mesh. Felite™ FC108-F performs excellently for water softeners treating water with iron or for treating extremely hard water. It shortens the diffusion path from the surface to the center of the bead and permits greater exposed surface area exchange sites resulting in higher kinetics than conventional resin yielding greater ferrous iron removal while providing the same softening capability.

Felite™ FC108-F is also used in combination with activated carbon to tremendously improve the smell, taste, and feel of water.
