Overview
Die-cut phlogopite micanite barrier plates for EV battery packs — the passive fire barrier between cells, over modules and under pack lids that contains thermal runaway. Mica is displacing polymer barriers because it is inorganic, arc-resistant and holds integrity beyond 800°C; EV fire-protection demand is the single biggest growth driver in the mica insulation market’s 5.56% CAGR trajectory. Pairs with Wedge’s WedGel aerogel pad range for combined thermal + fire barriers.
Supplied by Wedge Industries Limited with manufacturing and processing bases in India, UK, Spain and China, exporting to 45+ countries.
