Mica is a mineral which combines in itself so many desirable properties for the
qualifications imposed by the electrical industry. The most important property of Mica is
its micaceous structure, that is, they have highly perfect basal cleavage which permits it
to be split into sheets & films. Micas commonly occur as flakes, scales, or shreds.
Sheet muscovite (white) mica is used in electronic insulators (mainly in vacuum tubes).
Ground mica is used in paint, as joint cement, as a dusting agent, in well-drilling mud,
and in plastics, roofing, rubber, and welding rods.
The platelet particle shape of Mica offers excellent flexural
modulus properties, improved heat resistance, electrical properties and mechanical
properties. General reinforcing property and dimensional stability also adds to Mica's
advantage. It's major use are in Polyolefins.
