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.
