Resistance to chemicals meets high conductivity
The main features that distinguish expanded natural graphite are exceptional resistance to chemicals and good electrical conductivity.
Together with high-grade fluoropolymers, our thin, high-density SIGRACELL bipolar plates can be used for a broad spectrum of applications.
Thanks to their great resistance to corrosion, they are ideally suited for the demanding cell chemistry in battery systems.
