Felite™ FC108-B is an dark colored 8% crosslinked gel strong acid cation resin with standard mesh range, supplied in sodium form and it is primarily used in coflow regenerated industrial and residential softening applications that require good regeneration efficiency and oxidative stability. Its standard beads size distribution gives optimum operating capacity with minimum leakages of ions and also minimum pressure drop across the resin bed.

Felite™ FC108-B can be used for demineralization in industrial water treatment when regenerated with mineral acids (hydrochloric or sulphuric acids) as the hydrogen form cation resin.

Principal Application:
Softening – Industrial;
Softening – Potable Water(When ordered as Felite™ FC108-BP);
Demineralization(When ordered as Felite™ FC108-BH);
