Adaptable sizes – including large-scale needs
The sizes we provide are even enough to cover the needs of large-scale redox flow systems. We supply battery felts in standard sizes up to 1350 mm (53") in width in 25 m (82 ft) rolls. Beyond that, we produce carbon and graphite felts in customer- specific dimensions.
