Johns Manville’s engineers have developed highly specialized substrates for use in various battery applications.

Our chemically-resistant glass nonwoven is specifically designed for automated lead pasting systems.  Durability, resistance to wear and chemical breakdown make these carriers the choice for tough applications like lead acid batteries.

JM separator veils come in a multitude of thicknesses and widths to meet your separator application needs.  These glass mats are chemically resistant and repel chemical breakdown when exposed to conditions such as those found in lead acid battery applications.  Our polyester spunbond grades for gauntlets in stationary and traction batteries provide high stiffness and a superior uniform porosity as well as high durability and outstanding corrosion resistance.  Whatever your energy storage application is, look to JM for leadership powered by innovation.
