N -31X (SiO2) is hybrided by SiO2 and Perfluorinated ion exchange Resin . Thus our film has many outstanding features. It not only has the high tensile strength ,high selection,isotropy,high conductance;but also has the effect of self-umidifying and with low Linear Expansion.It can beused

in high temperature fuel cells and self-humidifying fuel Cells.

Package:

N -31X (SiO2) is packaged by Plastic bucket. Special Package please indicate.
