Overview
Thin die-cut mica sheet for EV busbar wrap, module wall lining and high-voltage creepage barriers. Combines dielectric strength with flame and arc resistance in a part thin and light enough for pack-level weight budgets — the electrical side of the EV mica opportunity, alongside thermal runaway barrier plates.
