Details Introduction

The Cm series perfluorinated ion exchange membrane adopts a new process to prepare ion exchange membranes, which not only have advantages such as high tensile strength, isotropy, high conductivity, and good chemical properties, but also have a self humidifying effect.

After testing, the mechanical strength of the same thickness and size exceeds 80% of that of traditional imported films, while the swelling rate is low and the moisture content is high. The CME series perfluorinated ion exchange membranes are particularly suitable as solid electrolyte separators in fuel cells, vanadium batteries, electrolytic cells, electrodialysis, and electrochemical sensors.

Core technology: Wet process technology for producing perfluorinated ion membranes

Traditional foreign melt extrusion methodCM melt casting process
Imported equipment exceeding 10 million US dollarsLow equipment cost
Can only be used after film formation transformationAfter film formation, it can be directly used
High resin requirementsLow resin requirements
Easy to produce fish eye bubblesNo fish eye bubbles

Independently developed - achieved the regeneration and recycling of perfluorinated ion membranes.

Breaking monopoly - low membrane cost, high crystallinity, high tensile modulus, isotropy, long lifespan, breaking the monopoly of the market by foreign countries.
