Mica are sheet silicates historically significant for their ability to be split into large, thin sheets that are uniquely useful for their electrical, thermal, and mechanical properties. They have high electrical and thermal insulating properties; they are resistant to chemical attack; they can be split into
transparent or optically flat films; and they can be cut or stamped to shape.
Uses of mica:
1- Joint cements: muscovite is used in drywall joint compounds, where it contributes to consistency and workability, smooth surface finish, and resistance to shrinkage and cracking.
2- Coatings Fine-ground, -325 mesh and micronized mica grades are used in paint as a pigment extender and for dry film reinforcement. The inert, platy mica improves suspensi
on stability, controls film checking, chalking, shrinkage, and blistering, improves resistance to weathering, chemicals, and water penetration, and improves adhesion to most surfaces. Coarser grinds are used in textured paints, and wet-ground mica is used in high quality exterior house paints. High aspect ratio grades are preferred for porous surface sealers
to seal pores, control penetration, and reduce sagging and film cracking.
3- Plastics Finely ground, -325 mesh and micronized micas are used in plastics to improve electrical, thermal, and insulating properties. Mica is considered the most effective mineral for reducing warpage and increasing stiffness and heat deflection temperature in plastics. In general, mica reinforces crystalline better than amorphous polymers. Best results are obtained with nonpolar polymers when mica is pretreated with a coupling agent to improve wetting. Mica is used in both thermoplastics and thermosets. Its largest single use is in
polyolefins, even though it requires stabilizers to prevent degradation of polypropylene.
4- Drilling fluids Coarse, hammermilled (+10 mesh) mica is used in waterbased oilwell drilling fluids to prevent fluid loss into porous rock formations.

Mica is a group of naturally occurring minerals known for their ability to split into thin, flexible layers. It is commonly used in various industries due to its insulating properties, heat resistance, and electrical conductivity. Mica is often found in shades of silver, gold, and brown and is used in products like cosmetics, paints, electronics, and construction materials. It also serves as a dielectric material in electrical applications and as a filler in plastic and rubber manufacturing.

Mica

We produce all kinds of nonmetallic minerals, such as vermiculite, mica, quartz, feldspar, perlite and so on.What we produce is comply with internation standard.
