Glass Mat is a non-woven fabric made with glass microfiber. It has been available for more than 30-years and has been used in batteries worldwide.
Glass Mat is highly porous (90-95%) that can absorb more acid. Additionally, it has small pore sizes to maintain electrolyte levels in the battery. It is highly resistant to battery acid, oxidation, and heat, and can maintain its shape and strength after prolonged exposure to severe environmental conditions.
