FORBLUETM is our brand of separation solutions for various chemicals. New addition to this family is FORBLUETM S series - fluorinated sulfonic acid ion exchange membranes for a wide variety of electrolysis and electrodialysis processes.
FORBLUE™ S series Functions and Features
Fluorinated cation exchange membrane
FORBLUETM S-series is a fluorinated cation exchange membrane based on sulfonic acid polymer.
Wide range of products
FORBLUETM S-series offers a variety of functions depending on grade. We supply membranes with a much higher ion exchange functional group (depending on the grade up to 37% more than conventional membranes) realizing high ion permeability during use. We can also offer membranes with very high cation selectivity.
High mechanical strength and chemical resistance
FORBLUETM S-Series achieves high mechanical strength and is easy to handle by incorporating special PTFE fiber reinforcement into sulfonic acid polymer film. It maintains high cation permeability and also has high chemical resistance based on the fluorinated base polymer. It can be used in various circumstances including severe conditions.
Alkaline water electrolysis and PEM water electrolysis
Hydrogen is expected to be the next generation energy resource. Alkaline water electrolysis and PEM water electrolysis are considered to be high efficient production methods of hydrogen.
Redox flow battery
Redox flow battery is considered a safe, long life and large capacity rechargeable battery. It requires a membrane with high ion selectivity and low resistance properties.
Production and recovery of chemicals by electrolysis processes
A cation exchange membrane is used for production or recovery of chemicals by electrolysis processes. This type of membrane needs to be durable against acid or alkaline solution.
