BATTERY SEPARATOR APPLICATIONS The high purity and acid resisting nature of Evanite's glass microfibers make them the obvious choice in lead acid battery applications.  Found in both flooded and sealed battery types, the glass fiber plays a key role insulating the positive and negative electrodes, holding electrolyte where its most needed next to the electrodes, and providing channels for the escape of gasses evolved during charging. AIR FILTRATION APPLICATIONS The extremely fine diameter of Evanite's microfibers makes possible the fabrication of filters for the most demanding air and gas filtration needs, such as HVAC, ASHRAE, HEPA, and ULPA filters.  The purity and chemical resistance of the glass discourages mold or bacterial growth and contributes to long operating life for the filter.  Filter media containing glass microfiber can be rolled, pleated, wrapped, molded, sewn, or laminated to other substrates.  Filters using Evanite's glass microfibers can be found in hospitals, clean rooms, pharmaceutical plants, and other industrial and commercial installations around the world. LIQUID FILTRATION APPLICATION Evanite makes a broad range of microfiber  diameters, ensuring that we can meet the needs of liquid filtration applications as well.  Our fibers are found in filters for auto fuel and oil, hydraulic fluid, food and beverages, diagnostic test kits, pharmaceuticals, and chemical analysis. Evanite's glass microfibers form sheets that are flexible and compressible, making them easily processible into a filter element.  Being glass, they can be used at high temperatures where organic fibers would melt or burn.
