What is mica paper?
Cloud Mica paper is a thin, sheet-like material made from natural mica crystals. After high-temperature steaming and exfoliation into thin flakes, it is processed into sheets using papermaking techniques. It retains mica's insulating and heat-resistant properties (withstanding temperatures above 600℃), and is flexible and easy to process. It is often used as an insulating base material in motor windings, new energy battery packs, high-temperature cables, and other applications, making it a key material in industrial insulation.Main Types of Mica Paper
1. Muscovite Mica Paper
Source ：Derived from natural muscovite (rich in aluminum).
Core Characteristics

Continuous Operating Temperature: 400-500°C (Short-term: 600°C).
Offers high cost-effectiveness and high availability.
Best Suited For ：Low to medium voltage electrical equipment (motors, transformers), household appliances, and building wires.
2. Phlogopite Mica Paper
Source ：Made from natural phlogopite (rich in magnesium).
Core Characteristics
Dielectric Strength: 12-25 kV/mm.
Continuous Operating Temperature: 600-700°C (Short-term: 800°C).
Possesses excellent high-temperature resistance and resistance to weak alkalis.
Best Suited For ：High-temperature industrial furnaces, metallurgical equipment, and aerospace engine insulation.
3. Synthetic Mica Paper
Source ：Artificial fluorophlogopite (laboratory synthesized).
Core Characteristics
Dielectric Strength: 25-40 kV/mm.
Continuous Operating Temperature: Up to 1000°C.
Ultra-pure (more than 99% mica content) with minimal impurities.
Best Suited For ：High-precision applications (nuclear reactors, advanced electronic products, and aerospace components) requiring extremely high reliability.
4. Calcined Mica Paper
Source ：Made by high-temperature calcination (800-1000°C) of natural or synthetic mica.
Core Characteristics
Dielectric Strength: 20-35 kV/mm.
Continuous Operating Temperature: 600-900°C.
Enhanced thermal stability (no moisture or volatiles).
Best Suited For ：Industrial kilns, exhaust systems, and solar thermal equipment exposed to high temperatures for extended periods.
Why Choose Mica Paper?
All types of mica paper possess unparalleled dual characteristics of "insulation + heat resistance," surpassing materials like fiberglass or plastic films in harsh environments. Its flexibility allows for use in confined spaces (such as coil windings, furnace linings), while its compatibility with adhesives and resins enables integration into composite insulation systems. The appropriate type is selected based on temperature requirements, voltage rating, and cost—mica paper provides tailored solutions whether for everyday appliances or extreme aerospace conditions.
