Glass Fiber Separator with High Porosity

Fiberglass diaphragm comprised primarily of glass microfibers and are produced with a wet laid process similar to that used for production of paper. With strong oxidation (acidic and alkaline) resistance and high temperature resistance, these separators are popular in Na and Zn battery research. Standard rolls are 60 and 120mm wide x 5m in length.
