Features
  • FORBLUE ™ S-series is a cation exchange membrane with a sulfonic acid group.
  • High cation selective permeability for effective electrolysis or electro-dialysis.
  • All materials that make up the membrane (including the reinforcing fabric) are made from fluorinated resins - as a result robust chemical resistance is ensured.
  • The membrane is reinforced by special PTFE fabric and has high strength and is easy to handle.
  • We have several types (dry/wet) and grades of membrane.


Properties
  • We have three types of membrane with different ion exchange capacities.
  • Dry and wet types are both available for Sx-2301.
  • WN grade, a wet type membrane, is recommended if it is always in contact with any liquid.
  • A counter ion can be replaced by a pretreatment.
