Mica
Mica is a non-metallic mineral widely used in various industries. The most commonly utilized forms in industrial applications are Muscovite Mica and Phlogopite Mica.
Phlogopite Mica
Phlogopite mica is a unique mineral with a powerful combination of thermal stability, electrical insulation, and layered flexibility, making it an essential material across multiple industrial sectors. As a member of the mica group, phlogopite is distinguished by its magnesium-rich composition and golden-brown,coppery red, greenish tint appearance. Its chemical formula is: K(Mg₃AlSi₃O₁₀)(F,OH)₂.
Exceptional Properties of Phlogopite Mica
Mica boasts outstanding dielectric characteristics, including:
- High insulation strength and excellent resistivity
- Low dielectric loss, arc resistance, and corona resistance
- High-temperature resistance and stability under rapid thermal changes
- Chemical resistance to acids and alkalis
- Perfect cleavage, allowing it to be split into ultra-thin sheets
- Elasticity and flexibility, making it easy to punch, cut, bond, and roll
Phlogopite Mica Sheets
Phlogopite Mica Sheet is a rigid or flexible insulating material formed by bonding mica paper with high-performance organic silicone resin under heat and pressure. It contains approximately 90% mica and about 10% resin. It has excellent insulating performance at high temperatures. Operates reliably in working environments ranging from -200°C to 1000°C, with dielectric strength up to 15KV/mm.
Specifications of Phlogopite Mica Sheets
- Thickness: 0.15~6mm
- Dimensions: 1000*600mm, 1000*1200mm, 1000*2400mm
- Available in custom sizes
- Available with PSA application
Wide-Ranging Industrial Applications
Thanks to these exceptional properties, mica is indispensable in multiple industries, including:
- Electric Vehicles, Battery System
- Household appliances
- Electronics & Electrical Engineering
- Capacitors, vacuum tubes, carrier wave equipment, oscillators
- Insulation for high-voltage and high-power generators, motors, DC machines, and electrical devices
- Marine & Transportation
