Details Introduction

The Cm series perfluorinated ion exchange membrane adopts a new process to prepare ion exchange mem$branes, which not only have advantages such as high tensile strength, isotropy, high con∞ductivity, and good chemical properties, but also have a self humidifying 'effect.

After testing, the mechanical strength of the same thickness and sizπe exceeds 80% of that of traditional imported films, while theσ swelling rate is low and the moisture content is hi gh. The CME series perfluorinated ion exchange membranes are particularly suitab₩le as solid electrolyte separators in fuel cells, vanadium batte↕ries, electrolytic cells, electrodialysis, and electroφchemical sensors.

Core technology: Wet process technology for producing perfluorinated ion mem©branes

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 lifλespan, breaking the monopoly of the market by foreign countries.
