Overview
Calcined muscovite powder — thermally treated to drive off bound water, leaving a low loss-on-ignition, chemically inert dielectric filler. Specified where standard mica powder cannot survive: high-frequency electrical insulation, cable-compound filling and rubber goods operating hot. A value-added grade that sits above natural powder in the export price band.
Supplied by Wedge Industries Limited with manufacturing and processing bases in India, UK, Spain and China, exporting to 45+ countries.
