Ahlstrom advances energy storage performance with new FortiCell™ glass fiber tissue solutions
AHLSTROM OYJ, PRESS RELEASE, JULY 6, 2026 at 17 EEST
Ahlstrom, a global leader in fiber-based specialty materials, is advancing the capabilities of its FortiCell® energy storage portfolio with a new range of glass fiber tissue solutions. The high-performance glass fiber tissue (GFT) solutions are designed to help battery manufacturers enhance efficiency, reliability and performance across demanding energy storage applications.
As electrification accelerates across industries, including automotive starting systems, forklifts and data center backup, manufacturers require materials that combine performance, process efficiency and reliability. With its comprehensive FortiCell® portfolio, Ahlstrom offers battery manufacturers a one-stop-shop approach for differentiated nonwoven solutions, including pasting papers, AGM separators and glass fiber tissue.
Designed for seamless integration into existing production environments, the new glass fiber tissue range includes both; thin grades for pasting processes, targeting battery manufacturers, as well as heavier grades for reinforcement of polyethylene (PE) separators. This dual positioning enables Ahlstrom to support multiple applications with a single material platform.
Glass fiber tissues are designed to ensure consistent performance in demanding applications. High dimensional stability supports reliable behavior during high-speed assembly, while a controlled fibrous structure contributes to low electrical resistivity and efficient battery operation. Fast acid absorption and wicking enable efficient and uniform battery filling, and good processability allows smooth integration without process changes.
Produced at Ahlstrom’s established operations in Europe and North America, the solution supports consistent quality, dependable supply and seamless integration for battery manufacturers.
“With our new glass fiber tissue solutions and the existing FortiCell® portfolio, we are strengthening our ability to support customers worldwide with reliable materials, process compatibility and deep application expertise,” said Stéphanie Pigeot-Rémy, Head of Global R&D and Product Development, Filtration at Ahlstrom.
