Fine particle size mica is used as a flux coating for metal welding rods. Micron size mica, preferably calcimined, is also used in cosmetic applications, i.e. nail vanishes, lipsticks, eyeshadows and barrier cream. Some of these micas are coated with oxides or iron and titanium. Many new applications are recognized in the automobile industry such as fan blades, dashboard panels, floor and grill panels, plastic seats, ignition system parts, air conditioning and heater housing, etc. Mica is replacing asbestos in acoustic compounds that eliminate road and engine noise.
Mica is also an environmentally accepted replacement for asbestos in brake linings.
High heat resistance, excellent mechanical and thermal strength, low moisture absorption, high surface leakage resistance, unusual chemical resistance and non-hydroscopic properties are some of the distinctive mica qualities. Mica particles are stronger than iron and are not brittle like other inert material. These contents can be adjusted depending on application.
