Overview
Silicone-bonded phlogopite micanite — the high-temperature end of rigid mica plate, holding its dielectric and mechanical properties towards ~800°C continuous where epoxy-muscovite grades stop near 500°C. Silicone-bonded plate sits at the top of the US$ 4–15/kg micanite band and is the material behind furnace insulation, industrial heating elements and the EV battery fire barriers now driving worked-mica demand at 5.6% CAGR.
Supplied by Wedge Industries Limited with manufacturing and processing bases in India, UK, Spain and China, exporting to 45+ countries.
