In industrial manufacturing and daily life, mica products stand out with natural merits and stable performance, safeguarding equipment safety and underpinning industrial development. Used for insulation protection in high-voltage electrical equipment, safety assurance in new energy sectors and heat-resistant linings in household appliances, they have become indispensable functional materials thanks to diverse forms and superior properties.
Mica is a kind of layered silicate mineral that can be split into ultra-thin flakes along cleavage planes. Its unique crystal structure endows it with multiple superior properties：
Thermal Stability
Various mica types feature outstanding temperature resistance. Muscovite withstands long-term 500℃, phlogopite up to 850℃, and synthetic mica performs better with instant peak temperature over 1200℃. It resists softening and cracking under high heat, and is non-flammable and distortion-free in open fire.
Reliable Insulation
It boasts excellent electrical insulation and high dielectric strength, effectively blocking high voltage current to avoid electric leakage and short circuits, ideal for high-voltage electrical systems and high-frequency equipment.
Stable Overall Performance
It has stable chemical properties with acid and alkali resistance and anti-aging capability, barely reacting with most chemicals. Combining flexibility and mechanical strength, it is bendable and crack-resistant, suitable for complex working conditions and various processing.
Eco-friendly & Safe
Free of toxic and harmful substances, it emits no poisonous gas, little smoke and peculiar smell at high temperatures, complying with green production and safe application standards.
Processed from natural mica with inherent properties, it can be made into products in various forms to meet diverse application demands：
Mica Plate
Hot-pressed from mica paper bonded with silicone resin, available in rigid and flexible types. Rigid mica plate features high strength for thermal insulation liners and insulating partitions; flexible one is bendable, ideal for slot and turn-to-turn insulation of motors.
Mica Tape
Band-shaped products made of mica base and reinforcing materials. It is flexible and fits closely when wrapped, widely used for insulation wrapping of motors and cables, especially for high-voltage motor coils.
Mica Tube
Rolled and pressed from high-grade mica materials, featuring insulation, flame retardancy, heat and pressure resistance. It serves as insulating protective sleeves for electrical appliances, high-temperature equipment and wiring circuits.
Custom Mica Components
Precision tailor-made mica parts with superior heat resistance and insulation, applicable for special-shaped insulating structures, thermal insulation fittings and customized electrical insulation assemblies.
Full-range Application: Penetrating Core Industries
With superior performances, mica products are widely applied in industry, new energy, home appliances, building materials and other fields to satisfy diverse working conditions：
Electrical & Electronic Industry
As core insulating materials, they are made into insulating parts for motors, transformers and capacitors, as well as insulating brackets and partitions for high-voltage electrical appliances and electron tubes, ensuring stable operation of electrical equipment.
New Energy Sector
In new energy vehicles, they provide high-voltage insulation, heat insulation and fire protection for battery packs, busbars and other key components. In energy storage systems, they deliver insulation and flame-retardant protection to ensure long-term safe operation.
Home Appliance & Daily Necessities Industry
Used in microwave ovens, electric irons, hair dryers, heaters and other household appliances as brackets, gaskets and partitions for heating elements, resisting high temperature and ensuring safe use.
Metallurgical & High-temperature Industry
Applied as thermal insulation linings and furnace door seals for industrial furnaces, and thermal insulating layers for high-temperature pipelines to resist high-temperature corrosion.
Building Materials & Chemical Industry
Mica powder serves as filler to improve weather resistance, impermeability and insulating property of coatings, plastics and rubber. Mica ceramic parts are used as electrical insulators for communication and radio fields.
