Chemical-resistant membranes for electrolysis

By Mary Page Bailey and Gerald Ondrey |

Forblue S-Series ion-exchange membranes (photo) are designed for electrolysis and electrodialysis applications that require robust chemical-resistance performance. Because they are made from fluorinated resins, all S-Series wet and dry grades ensure chemical resistance and mechanical strength, while providing outstanding current-carrying capability. Forblue S-Series grades are cation-exchange membranes with a sulfonic acid group. They provide high cation-selective permeability for electrolysis or electrodialysis and offer ion-exchange capacities from 1.0 to 1.25 meq/g. The high ion-exchange capacity enables very low resistance with high ion selectivity. S-Series wet and dry membranes are available in a wide array of thicknesses. If processing requirements demand reinforcement, S-Series membranes are available with special polytetrafluoroethylene (PTFE) fabric. — AGC Chemicals Americas Inc., Exton, Pa.
