Mica

Products

Mica has muscovite, biotite, phlgopite, lithium mica etc variations, muscovite is the most common mica.
Mica characterizes higher insulation, heat insulation, acid resistance, alkali resistance, low thermal expansion. No matter how fine it's crushed, the particle is of flake shape, and has good flexibility and toughness. Mica powder has good flowability, spreadability and adhesion.
Mica Powder is widely used in dielectric, insulation, paint, fire extinguish, plastic, rubber, ceramic, oil drilling, welding rod, cosmetic, astronavigation. etc
