Muscovite

Muscovite
1. Characteristics and uses of mica powder
Mica has muscovite, biotite, phlogopite, lepidolite and other types. Muscovite
is the most common mica.
Mica has high insulation performance, heat resistance, acid resistance, alkali
corrosion resistance, and small thermal expansion coefficient. No matter how
broken it is, it is in the form of flakes, with good elasticity and toughness.
The mica powder has a large diameter-to-thickness ratio, good sliding
properties, strong covering performance and strong adhesion.
Wancheng Mica powder is widely used in the fields of insulation, heat
insulation, paints, coatings, pigments, fire protection, plastics, rubber,
ceramics, oil drilling, welding electrodes, cosmetics, aerospace, etc.
