DUMICO supplies all kinds of mica for various applications including optical applications heaters, glass protection and electrical insulation. Mica belongs to an important and fairly large group of minerals (alumina). This mineral is suitable for numerous applications. Muscovite mica is a clear transparent material (the brightness is depending on the quality). Most people know mica of the “glass” in old coal stoves and kerosene burners. Crude mica is split (in film layers up to 100th mm) and then customized and sorted by quality before further processing for the specific application. Typical thicknesses are 0.05 mm (electrical insulation) to 0.15 to 0.2 mm (sight and level gauge mica). Mica is found in sizes up to 650 cm², larger dimensions and bright qualities are less common, making their price rises rapidly.
