  • Product Description of Polyphenyl Ester FC-101

    DF2808 is the latest generation of high-performance perfluorinated ion exchange membrane launched by Dongyue Group in 2022.It has  low energy, high mechanical strength, high selectivity,high chemical/oxidation  stability  and  other characteristics.Especially in the production process of 30%-50%NAOH, the application of this product can significantly reduce the voltage.

    This product is a white thin film containing reinforcing materials,suitable for high electrical density and zero polar distance electrolytic cells, and applicable to all mainstream electrolytic cell types in the current market.

    The product has been equipped with cation exchange capacity  when leaving the factory. In order to ensure the best  membrane condition, please use  suitable solution for pretreatment before use.The side labeled ANODE must be aligned with the anode. Otherwise,irreversible damage will caused to the product.
